My name is Ken Presner. I am an independent researcher, inventor, author and health consultant with over 35 years of experience in electronics design, computer programming and the health supplement industry.

In 1989 I was paralyzed with Multiple Sclerosis. In 1994 I nearly died from Crohn's disease. My books My Recovery Protocol and Against All Odds show that I did not beat 2 incurable diseases and return to perfect health by accident. I invented The Ultimate Zapper and launched this website in 1996. The Ultimate Zapper's healing power was vital to my recovery.


The Medical System says my recovery is merely an anecdote and The Ultimate Zapper is just a gadget. What else is new?

Those who have read my books know that my recovery is the real deal. And thousands of people in over 70 countries who use The Ultimate Zapper know that it is also the real deal ... backed by a mountain of compelling proof that you will not find on any other zapper site.

This includes the Testimonial Archive with more than 1100 unsolicited stories. This also includes the unsolicited testing of dozens of zapper brands by Dr. Martin C. with his patients. Dr. Martin is one of many practitioners worldwide who use The Ultimate Zapper and who unequivocally endorse it.


For the past 25 years, using every important metric, The Ultimate Zapper has ranked as the #1 parasite and virus zapper worldwide. It is #1 in technology, #1 in power, #1 in effectiveness, #1 in testimonials, #1 in professional endorsements and #1 in popularity. In Japan, the word zapper = The Ultimate Zapper.

The Ultimate Zapper is also #1 in another very important department. It creates a revolutionary and extremely powerful Electroporation Effect that is unique in the world of zappers. The Electroporation Effect is created by only two other companies in the world -- Inovio Pharmaceuticals, Inc. and Eppendorf AG -- both FDA approved.


Since 1996, thousands of people all over the world have benefitted from The Ultimate Zapper's healing power. It has proved effective for over 100 conditions including influenza and serious lung ailments. It is the most powerful Parasite Zapper & Virus Zapper available.

The Testimonial Archive bears witness to The Ultimate Zapper's effectiveness with over 1100 unsolicited testimonials and thousands of private messages adding to this testament.

The Ultimate Zapper's healing power derives from the powerful synergy created by its unique formula of 12 True Features that is light years ahead of feature-poor Hulda Clark zappers.


Synergy -- the interaction of multiple features -- determines how powerful and effective a zapper is. There is simply no contest when the feature-poor competition faces the powerful synergy created by The Ultimate Zapper's 12 True Features -- with extra features added to the 2 Ultimate Models and 3 Premium Models.

Why doesn't the competition create synergy? Because they are wedded to the basic 2-feature Hulda Clark A6 battery zapper formula. They can therefore claim to be "Hulda Clark zappers". But that's all they can claim.

Because there's no synergy with feature-poor zappers -- only a basic therapeutic response at best. Which is why the competition has so few testimonials, and why the name Hulda Clark -- adopted without Dr. Clark's consent -- is their only claim to fame.

The Ultimate Zapper left Hulda Clark behind in 1996. It is the undisputed leader in the zapper industry, on the cutting edge of zapper technology via ongoing research and innovation. This is exemplified in the 2 Ultimate Models and 3 Premium Models that optimize The Ultimate Zapper's amazing synergy.


The competition offers up a long list of Bells & Whistles to try to disguise their feature-poor zappers. They put icing on the cake with a long list of unbacked claims.

But not a single competitor talks about the 12 True Features and synergy. Their feature-poor zappers cannot go head-to-head with The Ultimate Zapper. So, they simply avoid the subject -- including The Ultimate Zapper's superior 99.7% Duty Cycle that is backed by scientific studies and patents.

The makers of feature-poor zappers focus on more important matters. We find AutoZap "borrowing" The Ultimate Zapper's name to redirect traffic to their site ... and ParaZapper taking The Ultimate Zapper's name for his weak UZ battery zapper ...

... and Supreme Zapper's "Dr. Thomspon" not daring to introduce himself as "Dr. Thomspon" in his video but instead offering a simple "hello there" -- with no first name, no last name, no credentials, no location, no contact information. Why the secrecy?

Because he is WANTED for impersonating a medical doctor. So, a simple "hello there" is all we get as he poses in a white medical coat in front of an anonymous green screen, talking about how supreme his 5-volt battery zapper is. You can't make this stuff up, folks. There's a lot more in the Zapper Review.


Well ... after all the shenanigans, how do the competition's zappers stack up? These comprehensive Zapper Comparison Charts and this Compelling 16-metric Analysis  show that it's simply no contest. The competition can't get to first base. But this does not prevent them from claiming ...

... to be The Best Zapper. Well, it's hard to make the claim stick ... with so few features, a long list of unbacked claims -- and a list of Bells & Whistles as long as your arm. All supported by a mere handful of testimonials ... in contrast with The Ultimate Zapper's 12 True Features -- 1100 testimonials -- no unbacked claims -- no Bells or Whistles -- and a mountain of proof.

That proof includes 2 years of comparative field testing showing how The Ultimate Zapper kills parasites, viruses, worms, bacteria, yeast, mold, fungus and other pathogens faster, more effectively and completely than any competitor.

The Ultimate Zapper also kills dangerous pathogens that no other zapper can touch, confirmed by Dr. Martin C. (unsolicited).

The Ultimate Zapper's superior effectiveness is proved graphically with 3-D Scanning -- unique to The Ultimate Zapper. It is no surprise that not a single competitor provides any graphic proof in favor of their zapper.

1100 Testimonials on this site -- with 80 Cancer Testimonials and Lyme Testimonials and dozens of amazing Miracles -- are a stunning testament to The Ultimate Zapper's effectiveness. All are guaranteed unsolicited vs. a mere handful from the competition, with none designated unsolicited.



Relative Strength Charts show what happened after two years of field testing The Ultimate Zapper vs. 6 well-known competitors, based on a comprehensive cumulative point system. No contest.

Comparison Charts show The Ultimate Zapper's 12 True Features head-to-head with 28 competitors. Once again -- simply no contest. Here are two amazing unsolicited comparison testimonials.

Howard G. I am a therapist with cutting edge equipment. The Ultimate Zapper is the most effective device I have used, ever. Strong statement? Yes, especially as I have £20,000 [over $25,000] worth of healing equipment. I congratulate you on a simple device that will probably work on everyone.

Aug. 21, 2017


Besides the endorsement (below) by actress Karen Allen who destroyed Lyme disease in 24 hours with The Ultimate Zapper and the unequivocal endorsement by Dr. Martin C. ...

... professionals and experts worldwide have resoundingly confirmed the #1 rank of The Ultimate Zapper, including medical doctors, alternative health practitioners including naturopathic doctors, chiropractors and homeopaths, therapists from a variety of disciplines, electrical engineers, electronics experts, scanning specialists, various healers and dowsers.

Read the Professional Endorsements page.

A European electronics expert submitted (unsolicited) a scientific analysis with his professional oscilloscope views (below) of The Ultimate Zapper's harmonics. They are superior to all competitors. Harmonics are a key element contributing to The Ultimate Zapper's powerful synergy. They are essential to its effectiveness.

The Ultimate Zapper                   All Other Zappers

Some well-known competitors have even endorsed The Ultimate Zapper. Terminator's Don Croft pubicly endorsed The Ultimate Zapper declaring "it's a good zapper". He did not dare say more, understandably. And Thundervolt's Body Tester surprisingly endorsed The Ultimate Zapper during a zapper test. It was not supposed to do that, of course.

Dr. Hulda Clark who invented the first zapper defined zappers as pulse generators that use a positive offset square wave and a single frequency to kill all pathogens that resonate at all frequencies. This is the precise definition of The Ultimate Zapper.

But ParaZapper must have forgotten this when he unwittingly stated on the CureZone health forum that The Ultimate Zapper "may be the best single frequency zapper" -- which means the best zapper according to Dr. Clark. ParaZapper has been trying to take it back ever since.

ParaZapper has also been trying to clone The Ultimate Zapper ever since -- without success -- because The Ultimate Zapper takes zapper technology far beyond Dr. Clark's conception and far beyond any competitor. The Ultimate Zapper simply has no rival.


Karen Allen talks about
The Ultimate Zapper

on YouTube

The famous American actress Karen Allen starred with Harrison Ford in Steven Spielberg's Indiana Jones movie Raider's of the Lost Ark. Karen endorses The Ultimate Zapper in a special way. It changed her life forever.

Karen killed Lyme disease in one day with The Ultimate Zapper model SE. Karen now uses XE. Her testimonial is cited here with her permission.

In Karen's interview and on her Lyme Page she talks about her miraculous recovery and that of "15 or 16 people" who borrowed her Ultimate Zapper for Lyme. I encourage you to read all 40 of the stunning Lyme Testimonials including Karen's.

I was completely cured ...

Karen Allen. Ken, I never get sick at all anymore since I began using The Ultimate Zapper. Thank you so much for the part you play in getting it out into the world. It has had an incredible impact on me. After zapping for 4 hours ...

karen2I fell asleep ... I got up and I began to realize I felt dramatically different ... within about the next 48 hours all my Lyme symptoms had gone. I was completely cured by this wonderful little machine.

I am a true believer in the wonders of [The Ultimate Zapper] ... it was one of those eureka moments in my life. I know from my own experience that this works. I have even administered it to 15 or 16 people. It has helped all of them ...

All the best,
Karen Allen

Mike D. I decided to get [QE1] to help a man out who has had shingles for five years ... The doctors told him there's nothing more they can do. He's been in horrendous pain ... Nothing else has worked for this man except your zapper. Thank you for such an excellent and effective product.

JoAnn P. I have been zapping [with The Ultimate Zapper] for lupus and Lyme which at this point has been by far the BEST I have ever been!! I am ecstatic that the zapper makes me feel so much better.
Jul. 28, 2016


Dr. Martin C.

Dr. Martin C. No zapper (except yours) kills bone infections. No other zapper penetrates the GI tract, compromised cells or egg sacks (cysts) except yours ... it does 2 other things that no device can.

It destroys or deactivates GMOs and altered proteins and kills parasites in the GI tract, and that is unique to your zapper. It also kills parasites contained with cell nuclei and larva buried within cysts, again, unique to your zapper ...

You clearly have designed a fabulous product and your knowledge on this subject is extensive and impressive. I am absolutely dumbfounded that you have been able to produce such an effective product ...
Jan. 8, 2019

The ER

Robin S. I am not sure what to say but thank you. I had started on an antibiotic for a kidney infection and wham ... I woke up to swollen lips, tongue, throat, belly. I hooked up your [QE3]and started.

I can't believe my eyes. After the first 10 second session my lips began to shrink, tongue didn't hurt, throat didn't hurt, belly pain was going away.

I am in total shock. I was going to go to the ER. I am so glad I bought [QE3] ... amazing. After the 3rd session my lips are normal ... unbelievable ... I am thrilled with your zapper.

No contest

The Ultimate Zapper is the only zapper in the world with 12 True Features. Viewed opposite the competition's feature-poor lineup ... there is simply no contest. It is no surprise you will not see the 12 True Features even mentioned on any other zapper site. They offer up Bells & Whistles & unbacked claims in place of the real thing.

Unique technology
& Synergy

The Ultimate Zapper's superior performance is based on cutting-edge technology embodied in its unique formula of 12 True Features that create a powerful synergy -- a multifplifier effect via their well-designed interaction.

The 4 Premium models incorporate extra features that optimize this synergy thereby optimizing results. See the Premium Models and the Classic Models.

Moving from SE to XEplus to QE1plus to QE2plus to QE3plus to QE4 to QE5, you can expect much faster results with progressively deeper penetration.

The Ultimate Zapper provides indisputable proof of effectiveness and preeminence. It is the only zapper brand whose name is coveted by other zapper makers. In fact, AutoZap, ParaZapper and others have even tried (unsuccessfully) to adopt the Ultimate Zapper's name -- for the following reasons.

1. Innovative technology unique to The Ultimate Zapper is the secret to its #1 rank. The competition is a no-show opposite the powerful synergy created by The Ultimate Zapper's 12 True Features.

2. There is no better example of The Ultimate Zapper's superior technology than its 99.7% Duty Cycle that reaches deeply into the body -- backed by scientific studies and patents vs. a 50% Duty Cycle for Hulda Clark zappers.

This patent shows a minimum 88% Duty Cycle produces superior results. This study shows a 90% Duty Cycle reduces treatment time by 64%. Even Cold Lasers are now using an 88% Duty Cycle to improve results.

3. The Ultimate Zapper ranks #1 for effectiveness with 1100 testimonials in The Archive -- the only zapper site that guarantees unsolicited testimonials. This is 20 times the nearest competitor.

4. The Ultimate Zapper's #1 rank in the Testimonial Department is backed by countless testimonials lauding The Ultimate Zapper that have been posted on such respected health sites as CureZone, CancerTutor, Soul Guidance and many others worldwide.

5. Since 1996 thousands have overcome serious conditions with The Ultimate Zapper -- even terminal conditions. Many miracles have happened and many lives have been saved.

6. Professional Endorsements worldwide have confirmed that The Ultimate Zapper ranks #1 for superior technology & effectiveness.

7. Dr. Martin C. and this practitioner and this therapist and also this customer are among dozens who attest to the superiority of The Ultimate Zapper after doing head-to-head tests of The Ultimate Zapper with zappers from other makers.

8. The Ultimate Zapper is the #1 ranked zapper for networking. It is the only zapper with a worldwide network of distributors.

9. The Ultimate Zapper ranks #1 for site links. Far more sites link to The Ultimate Zapper than to any other zapper site.

10. Relative Strength Charts and Comparison Charts confirm that The Ultimate Zapper ranks #1. The Charts clearly show its technology is light years ahead of 28 well-known competitors -- backed by 2 years of comparative field testing.

11. EIS 3-D Body Scanning is scientific proof of effectiveness for The Ultimate Zapper, the only zapper backed by graphic scanning. The data base has hundreds of patient scans. EIS 3-D Scanning is cutting-edge technology used by 1500+ physicians world-wide.

12. The powerful therapeutic Electroporation Effect is created by only 3 companies in the world -- Innovio Pharmaceuticals, Inc. and Eppendorf AG (both FDA approved), and The Ultimate Zapper (with 3D scanning and clinical proof).

Electroporation potentiates acupuncture and homeopathy. It is also a natural blood thinner and it also greatly increases the uptake of medicines, vitamins, minerals, chelators, colloidal silver, herbs and supplements. Increased uptake means reduced dosages.

13. Harmonics are a vital feature contributing to The Ultimate Zapper's effectiveness. Scientific Evidence proving the superiority of The Ultimate Zapper's harmonics was submitted (unsolicited) by a European electronics expert, with oscilloscope views and detailed commentary.

14. It is so powerful, that zapping starts at 10 seconds with The Ultimate Zapper -- and many people don't need more. There are no 20-minute breaks with the 2 Ultimate Models and the 3 Premium Models thanks to Duration Zapping.

The competition has the 7/20/7/20/7 schedule for 61 minutes. Terminator, Mini Silver Terminator and Longevity advertise how weak they are with round-the-clock zapping -- and burn warnings.

15. Dr. Clark invented the first parasite zapper in 1993. Her research showed at least 9 volts is needed to produce therapeutic results. But battery zappers produce 9 volts for a short time then discharge ... to 8 volts then to 7 volts then down to zero.

Many competitors tout long-life batteries as though this will improve results. But long-life batteries do not create higher voltage. They simply allow for a slower discharge -- below 9 volts down to zero -- in sub-therapeutic territory.

The 6 Ultimate Zappers optimize therapeutic results because they are powered by 9-volt and 12-volt Universal AC adapters that convert to Direct Current. They guarantee constant high voltage -- 9 volts for the 2 Classic Models and 12 volts for the 3 Premium Models and the 2 Ultimate Models -- with no discharge.

16. Dr. Jerry. L. Tennant, M.D., wrote a series of scientific books entitled Healing is Voltage. His research confirms Dr. Clark's research and my 26 years of research into the direct link between The Ultimate Zapper's constant high voltage and its healing effects -- incorporated in the design of The Ultimate Zapper's 7 models.

The Ultimate Zapper creates an Electroporation Effect that is not only unique in the zapper world but also revolutionary, without exaggeration. This cutting-edge technology is backed by scientific studies and patents and is not created by any other zapper company. It is only created by 2 other companies in the world -- Inovio Pharmaceuticals, Inc. and Eppendorf AG -- both FDA approved.

The powerful Electroporation Effect greatly increases the uptake of vitamins and minerals, herbs, chelators, colloidal silver and medicines. It also potentiates acupuncture and homeopathy.

Increased uptake means greatly enhanced effectiveness for these elements and reduced dosages. The Electroporation Effect is also a natural blood thinner. Photos before and after Electroporation:

EIS Scanning (Electro Interstitial Scanning) is graphic scientific proof of effectiveness -- unique to The Ultimate Zapper.

See the amazing scans (below) of a male age 40 before/after using XE. The EIS Page has dozens of scans of women and men with a variety of conditions before/after zapping -- with hundreds more in the data base. The results speak for themselves.

EIS Scanning was developed in France as cutting edge 3-D imaging and diagnostic technology. It is used worldwide by 1500+ medical doctors for fast, efficient and precise patient diagnosis. Read more.

My Recovery Protocol

In 1989 I was paralyzed and bedridden with Multiple Sclerosis. In 1994 I nearly died on the operating table with Crohn's disease and was told the disease would be lifelong and that I would be back for another operation within 5 years.

It never happened. I fought for 7 years to get my life back -- with no guide to show the way. This was pre- Internet. The library was all we had. I recovered against all odds -- but not by accident.


This photo is from Japan
following the Minamata mercury disaster in 1956
I looked like this -- paralyzed and bedridden with MS
... following a dental mercury disaster in 1989

My Recovery Protocol (230 pages) is a study of the modalities that led to my recovery. This is invaluable information that is hidden by The Medical System.

Part 1 of My Recovery Protocol covers sources of toxicity, the chain of pathology, specialized lab testing (not offered by The System), specialized test analysis and test interpretation, and a whole host of conventional, herbal and "alternative" detoxification modalities (in great detail) that led to my recovery, including parasite killing.

Part 2 of My Recovery Protocol covers rebuilding and revitalization via the specific elements that promote recovery and create good health, including diet, supplements and lifestyle.


Toxicity is the root cause of many conditions, hand-in-hand with parasites and other pathogens that are attracted to toxins. This creates a chain of pathology. In my case, detoxification and parasite killing broke that chain and led to my recovery.

And, in my case, Multiple Sclerosis and Crohn's disease were caused by mercury poisoning from "safe silver amalgam fillings" that are 50% mercury but only 35% silver -- approved by the FDA. And also with FDA permission to call them silver fillings instead of mercury fillings, which is exactly what they are.

The ADA and FDA knew that the word mercury -- would scare away customers. So they found a way to market this deadly poison to unsuspecting dental customers. The convenient lie.


The System ... trying its best
to anaesthetize everyone with convenient lies

All conditions

My Recovery Protocol applies to all conditions with underlying toxicity issues, not just conditions caused by dental mercury. My book has universal application. People with a variety of conditions with different sources of toxicity have applied the lessons and modalities in my book and have duplicated my success.

Wheel chairs

People who studied My Recovery Protocol have left wheel chairs behind and reclaimed their lives. But this is just "anecdotal" -- like my own recovery, according to the The Medical System. They have their own agenda. "Anecdotes" of people's actual experience are cast aside -- because they reveal the truth.

My Recovery Protocol has empowered people to overcome many conditions by making truly informed choices. It's all about taking charge. My site and my recovery are lauded in Stephanie Relfe's book entitled You're Not Fat You're Toxic.

Against All Odds

Against All Odds (275 pages) is the blood-and-guts story of my fight to beat the odds. In 1989, I was poisoned by deadly mercury vapor during removal of silver fillings -- done without precautions. Still normal practice today. Silver fillings. They are 50% mercury. That's the beginning of The Big Dental Lie.

In a few weeks I was paralyzed and bedridden. I was diagnosed with Multiple Sclerosis (MS) at Mt. Sinai Hospital in Toronto. I was given no hope of recovery. But positive thinking, willpower and prayer are powerful things. My first priority was learning to walk again.

In 1993 I was diagnosed with Crohn's disease at St. Paul's Hospital in Vancouver. Emergency surgery followed. I nearly died on the operating table, then languished for 6 weeks in hospital, in a twilight zone between life and death.


I looked like this in 1994 after Crohn's surgery
-- with my hospital ID wrist bands (right)

But surgery does not cure Crohn's disease. Once discharged, I began searching for answers. I was convinced the two diseases were linked. Years of research followed with many dead ends. This was pre-Internet. The library was all we had.

I eventually came to the conclusion that The Dental System, with The Medical System as their loyal partner, caused both diseases by grandfathering mercury fillings into The System through the FDA's back door -- encouraged by the ADA -- without safety testing. The FDA is notorious for avoiding safety testing when there is money to be made. The FDA knew they could not prove that the #1 neurotoxin on the planet is safe. So, they had to find a way to get it into The System.

That's where grandfather entered the picture. Who needs the front door and safety testing when grandfather is holding the back door wide open? Problem solved.

Oh, I forgot to mention. The ADA just happened to own the two patents on mercury fillings. And I forgot to mention that there is a revolving employment door between the FDA and the ADA.


The ADA's revolving employment door
with the FDA

Things may look bad at this point, but the ADA and FDA always have a way out. A perpetual mantra. They proclaim, in unison, that once mercury is in your mouth it is no longer toxic.

According to the FDA and ADA, the #1 neurotoxin on the planet becomes inert and non-toxic when "placed" two inches from the human brain. Yah, sure. And my name is Eleanor Roosevelt. As though this egregious lie needed to be disproved ... Dr. Murray Vimy in Calgary did just that.

Inside the Ultimate Zapper

ADA Headquarters in Chicago
-- a monument to toxic dental mercury

But wait. Mercury fillings are not metal at all. According to the FDA they are classed as a "device". You can't make this stuff up. A bureaucratic transformation has magically occurred. And a very convenient one, at that. Because, if mercury is no longer a metal it cannot be a toxic metal. Right?


Mercury toxicity is simply a no-brainer
... with the FDA and ADA mocking the truth

The ADA and FDA knew from the beginning that mercury was highly toxic -- the #1 neurotoxin and the #2 toxic metal on Planet Earth. But greed raised its ugly head. The desire for profit got in the way ... and the cunning bureaucrats had their way.

But just think for a moment ... what kind of System deliberately sets about poisoning entire generations via mercury with the inevitable result being disease and premature death for millions?

The Ultimate Zapper

What are you looking at me like that for?

Well, obviously, a corrupt and criminal System without empathy or conscience. Well ... that just happens to be the exact definition of psychopathic. But the scariest part of the situation is ... the whole thing is perfectly legal.

When I realized that The System was not on my side but on its own side, I knew I had to step out of the box to have any hope of recovery. This enabled me to discover mercury-free dentistry, alternative medicine, detoxification and parasite killing.

All of which enabled my eventual recovery. But I was so ill that it took 7 years of blood, sweat and tears to claw my way out, escape the nightmare and return to perfect health. By 1996 I was well again.

The MS Society of Vancouver heard about my recovery and invited me to give a speech at their annual gathering in 1997. They were not prepared for what I had to say. I gave them hell.

Neurologists from the Vancouver MS Clinic were in attendance -- conspicuously silent, knowing full well that they profit from the misery of their fellow humans by conveniently avoiding the subject of dental mercury. And thus denying them the care they need -- safe dental work, detoxification and parasite killing.


The ADA and FDA say ...
"trust us ... mercury fillings are safe"
... while neurologists look the other way

Well ... how did the audience receive my message? They tried to shout me down. They couldn't stand hearing the truth, which included the fact that The System also stacked the odds against my recovery -- and against the recovery of those with MS in the audience. Denial was also in attendance that day.

No neurologist will ever say "open wide, let's see if you have any mercury fillings". And that includes the neurologists at the MS Clinic. Why? Because their living depends on looking the other way. In fact, the top neurologist in Vancouver laughed me out of his office when I proposed dental mercury as a cause of MS -- during a 3-hour discussion with him after I had recovered.

So ... it was obvious that there was a zero % chance of recovery inside The System. Because their track record showed a zero % success rate. Not a single recovered person in their long history. With all the billions of dollars in the bank ...

... they have not been able to produce a single recovery. What I was able to do on a minuscule budget, they were not able to do with their billions. Why?

Because The System is not interested in recovery. Recovery is not profitable. The System's profit is based on return customers. A recovered person is not a return customer.

So, The System makes darn sure it gets return customers -- by causing disease and then turning their back on cures. After all, The System has to make a living, doesn't it?

So ... the vast majority of people with MS bet on a losing horse at the race track, because The System is a clear loser with a zero % success rate. Personally, I didn't think that betting on a proved loser was a wise choice ...


Riding The System's horse

... the loser consisting of the MS Clinic and the MS Society -- backed by Health Canada, the Canadian Medical Association, the Canadian Dental Association -- all under the umbrella of the FDA, the AMA, the ADA, the MS Foundation and the Crohn's establishment.

So, I walked away. And by walking away from The System, I was able to beat the odds. The bottom line is ... even those facing serious illness and a dim prognosis may be rewarded with the hope of recovery after reading the amazing story of how I beat the odds and got my live back. Read more.


Empowerment -- it's in our hands


Risks of Chelation (180 pages) contains the most accurate and comprehensive information available anywhere about the relative dangers of heavy metal detoxification (including mercury) and the potential problems when chelating with DMSA, EDTA and DMPS.

Risks of Chelation focuses on both pros and cons of DMSA, EDTA and DMPS chelation -- with special attention to potential risks. It provides invaluable information for those who want to proceed safely through the detoxification process after the removal of "safe silver amalgam fillings" that are 50% mercury. Read more.


Dr. Hulda Clark invented the first zapper in 1993. She was a great innovator. But she never developed a powerful zapper. She stuck with her basic 2-feature A6 battery zapper for the sake of continuity in her research.

There is great irony for makers who call their zappers Hulda Clark zappers. By copying Dr. Clark's A6, trying to ride her coattails, they are admitting their zappers are as weak as the A6. They add Bells & Whistles -- Fake Features -- to make it look like their zappers have something special to offer.

And many competitors add extra frequencies to make people believe this will improve results. They only wish. Dr. Clark proved "sophisticated gizmos" that add frequencies are no more effective, in spite of the claims. Adding frequencies to try to compensate for a feature-poor zapper does not create a feature-rich device.

Definitive Zapper Comparison Charts prove all Hulda Clark zappers are feature-poor. This may surprise, but the proof is there in the charts that highlight all important metric standards.

So, it is no surprise that the weakness of Hulda Clark zappers is reflected in their lack testimonials, a mere handful at most. Even at that, no other zapper maker says their testimonials are unsolicited. I guarantee that all 1100+ testimonials on this site are unsolicited.


Many zapper makers call their devices "Hulda Clark zappers". But Dr. Clark was never associated with any zapper maker. She never endorsed any zapper, never approved any zapper and never gave her consent to any zapper maker to use her name, including ... AutoZap, ParaZapper and Dr. Clark Research Association.

But what about "The Zapper Personally Approved by Dr. Clark"? Well, this "approved" zapper is a newcomer. It did not exist when Dr. Clark was alive. Dr. Clark died in 2009. So, that's quite a claim. And since their zapper is simply a copy of Dr. Clark's weak A6 battery zapper it has nothing to shout about -- except a false claim.

And there are many Hulda Clark Shops and Hulda Clark Stores. But Dr. Clark never sold zappers. Not one "Dr. Clark Shop" or "Dr. Clark Store" ever received Dr. Clark's consent to use her name.



Bells & Whistles are called features by some makers. But they are really Fake Features. They contribute nothing effectiveness. The competition's list of features is full of Fake Features vs. The Ultimate Zapper's 12 True Features.

A case in point. AutoZap is at the bottom of this definitive Comparison Chart that showcases the 12 True Features that create power and results. But the AutoZap Comparison Chart tells a different story because their chart contains onlyFake Features.

Their chart was obviously created to make AutoZap stand out. The truth is that AutoZap has only 1 True Feature. Of course, they couldn't put this in their chart. You can't advertise a zapper with one feature. So, they had to use fillers -- Fake Feature -- to make things look good ...

"... long life battery, automatic shut-off, beeper, LED display, timer, carrying case, belt clip, low battery sound alert, sleek design, push-button switches, protection against incorrect battery installation, straight cables ... ". The list goes on and on.

The bottom line is that The Ultimate Zapper is light years ahead of the competition -- clearly shown in this Comparison Chart, this Comparison Chart and these 5 Comparison Charts.


The competition ... is still working on it


Dr. Clark stated that most people will choose the zapper option rather than go to the trouble and expense of a frequency generator. Here's why.

There is a world of difference between frequency generators and zappers -- especially The Ultimate Zapper. Frequency generators are complicated devices. They first require discovering the frequency for each pathogen with a diagnostic device like a syncrometer. Then the frequency generator dials in each frequency individually for individual treatment -- a very time-consuming and expensive procedure.

The Ultimate Zapper makes things easy with no syncrometer or other diagnostic equipment required and no dialling of frequencies. Many people don't realize that The Ultimate Zapper's technology is driven by a single frequency -- not multiple frequencies. Here is how this magic works to kill all pathogens at all frequencies.

And with The Ultimate Zapper there is no complicated manual, there are no programs to worry about, there are no confusing charts or flashing lights or beepers to figure out, and there is only one mode -- the healing mode. And it's automatic.

The Ultimate Zapper takes the confusion and frustration out of zapping. Just flip the switch and away you go. As simple as that.

Extra frequencies

Some zappers add extra frequencies to make people think this will improve results. They go by the names Frequency Zapper, Programmable Zapper, Rife Zapper, Digital Zapper and Sweep Zapper.

But Dr. Clark proved "sophisticated gizmos" that add frequencies are no more effective, in spite of the claims. Adding frequencies to try to compensate for a feature-poor zapper does not create a feature-rich device.

Features (plural) create a feature-rich and effective zapper. The synergy of 12 True Features is the secret to The Ultimate Zapper's success. Frequency is just one element in The Ultimate Zapper's line-up. Read about the relative importance of frequency.


From Arthur Doerksen
on the AutoZap site

These units require a solid commitment to master. Prepare to practice 1 to 2 hours per day for 3 months to become proficient.

The AutoZap site markets diagnostic devices called syncrometers for use with frequency generators. Frequency generators depend on syncrometer diagnosis or other diagnostic procedures.

Using a syncrometer is expensive, complicated & time-consuming, as Arthur Doerksen of AutoZap explains. Dr. Clark said most people will choose to zap rather than go to that trouble & expense.

The Ultimate Zapper makes everything so easy. You don't need a syncrometer or any diagnostic equipment. There are no confusing modes or programs. Just flip the switch and away you go. There is only one mode -- the healing mode. And it's automatic.

"There is nothing in the design of the Para[Zapper]
that puts it anywhere above the original
Clark zapper built in a shoebox! "

David Etheredge of ParaZapper has become famous for his gaffes. He started off misrepresenting his credentials on his site. He was pretending to be an electronics engineer but got caught red-handed -- then tripped over his feet with interesting excuses.


After he was caught out

Which leads us to his disinformation campaign against this site that goes back over 15 years -- totally unprovoked. David Etheredge has tried his best to convince people that The Ultimate Zapper is a "rinky-dink" device ... that accidentally created 1100 unsolicited testimonials.

Mr. Etheredge has expended a lot of energy trying to distract people from his terminally weak zappers by pointing a derogatory finger at The Ultimate Zapper -- and me personally, including some hilarious personal insults.

My favorite is his declaration that I am a certified "shade tree mechanic" who invented a piece of junk ... that accidentally created 1100 unsolicited testimonials.

But then Mr. Etheredge had a change of heart. He did a U-turn. He decided to endorse The Ultimate Zapper on CureZone, boldly declaring "it may be the best single frequency zapper". But once he realized he'd put his foot in his mouth he tried to take it back. He's still trying to take it back. Just one more gaffe to his credit.


David Etheredge's
Testimonial Nightmare

After all these shenanigans, what did the covetous Mr. Etheredge do? He tried to clone The Ultimate Zapper (unsuccessfully) and named his weak UZ battery zapper after The Ultimate Zapper. I mean, you can't make this stuff up.

Mr. Etheredge then figured he had it made ... by authoritatively declaring that I made up the Testimonial Archive. He dug himself a very deep hole with that one.

The compelling proof in favor of The Ultimate Zapper is simply overwhelming. No competitor comes even close. In frustration, Mr. Etheredge decided to waste time trying to deceive people. Better to have spent the time trying to improve his weak zappers.

ParaZapper is still trying to figure out
how to get to square one


I think it's ...
over here somewhere

For all his efforts Mr. Etheredge has become an icon in the zapper industry -- unabashedly displaying his duplicity, his covetousness and his legendary ambivalence for all to see. Yes, David Etheredge has a very interesting business model. But actually, he has only one problem with the truth. He is allergic to it.


Amazingly, some people are actually duped by his shenanigans. Well ... those who are considering a ParaZapper may wish to think twice after reading the Testimonial Archive on this site with over 1100 unsolicited testimonials -- and a dribble for ParaZapper.

Think it over ...

Some people may wish to think it over three times after reading the email from Sept. 11, 2019 (below) from Alastair T., a very disappointed ParaZapper customer.

Dear Ken, Unfortunately I am one of those people that has been fooled some of the time. As I buy things online I rely to a degree on peoples integrity and honesty (which you have an abundance of).

I am terribly disappointed that I didn't come across your zapper before purchasing the para zapper uzi. I thought I had done my due diligence but obviously I didn't dig deep enough.

I have had the uzi for about 3 weeks and was told the rechargeable batteries I purchased would last around 7.5 hours. I got 1.5 to 2 hours and have just had to send it back for repair [from Australia to the US at his own expense] as the power light stopped working ... terribly disappointed.

And some people may wish to think it over
four times after reading the devastating post
(below) from a third party on the CureZone
health forum about ParaZapper products.

Para [referring to David Etheredge of ParaZapper], You always say Para[Zapper] is not the average. I have seen absolutely nothing in the specs. that make it anything more than the average zapper.

There is absolutely nothing innovative about the Para[Zapper] products. There is nothing in the design of the Para[Zapper] that puts it anywhere above the original Clark zapper built in a shoebox!



For years, Arthur Doerksen of AutoZap was unable to find a way to improve his terminally weak zapper. He was stuck with the old Hulda Clark formula and couldn't figure out what to do. Then, he came up with a great idea to solve the problem.

He bought a copycat domain name -- Ultimate Zapper -- and created an Internet redirect to try to drive Internet visitors to his site. He hoped that people looking for The Ultimate Zapper would end up at his Ultimate Zapper page that redirected people to AutoZap. He kept this up for years.

But in the end, this didn't work out well for Arthur because the search engines caught onto the redirect ploy. Arthur eventually let go of the copycat name and abandoned the redirect project.

Arthur ...
re-directing traffic to his site

In 2021, Arthur is still seen on his site making claims for cancer and his Integrated Wellness System. Sounds great. But you may notice that his most recent videos and photos go back at least 10 years. And if you try sending Arthur an email you will not receive a reply. Something is not right here.

Arthur Doerksen
2008 photo on his site

That's because ... Arthur died of cancer in 2016. God bless him. May he rest in peace. I knew Arthur in the 1990s. We did have our professional differences. But Arthur was a good man.

Arthur's son, Fraser, now runs the AutoZap site ... with no word of his father's passing. He still uses his father's name to promote AutoZap products and still takes orders using his father's name. But he doesn't answer emails or process returns or refunds.

Still on their site

"How I was healed of cancer. Wake up your immune system fast. Just 5 minutes and you are done!

I don't fear the C word any more because I've been through it twice and I finally learned the secret ... Today, I use my AutoZap 5 Hulda Clark Zapper every day to remain healthy and cancer free."

No reply

I read what you wrote about Arthur and you are right. I bought his AutoZap and this magnetic food thing and neither did anything at all. He promised a refund if they didn't work but would never reply to me when I asked several times. I even used some of my electronic [test] equipment I have here and those things were not putting out anything at all. John F.


Are you thinking about buying a Zappicator? You may think twice after reading their fictional claims about cancer. And you may think 3 times after reading breathtaking fictional claims they make for the zappicator.

Arthur states that Dr. Clark "found you can neutralize benzene and other toxins magnetically" with the zappicator. A bold claim. What does "neutralizing" toxins mean? What is the possible scientific explanation for this? And how did Dr. Clark "find" this? And ...   what if the toxins are not magnetic? Hmmm.

Well ... Dr. Clark doesn't say a word. And neither does Arthur. Mum's the word. The fact is ... there is no proof whatsoever for this fanciful claim -- from Dr. Clark or Arthur or anywhere else. The only thing Arthur offers up for proof is ... Dr. Clark's quote.


Fiction ... is stranger than truth

Well, if you're still considering a zappicator you may remember the customer (above). Because this sounds like a risky proposition according to this unhappy customer ...

... who reported, "He promised a refund if they didn't work but would never reply to me when I asked several times. I even used some of my electronic [test] equipment I have here and those things were not putting out anything at all. "


Are you sure you want to get into this
... without doing a bit of research?

But ... if you do finally decide to take the plunge and it doesn't work out for you ... surprise, surprise ... you're out of luck. AutoZap calls their Zappicator "a personal use item". They refuse to refund in case of dissatisfaction -- as per the information on their site and confirmed by the above customer report.

Read dozens of unsolicited Cancer Testimonials in The Archive on this site from people who beat cancer with The Ultimate Zapper -- without using a zappicator.


Supreme Zapper


for impersonating a medical doctor

Supreme Zapper is unique in the zapper industry. It is the only zapper couragous enough to "borrow" my text word-for-word in an effort to duplicate my site. This newcomer to the zapper world now takes the #1 spot in the Zapper Review -- for deception and outright fraud.

Launched in 2018, the Supreme Zapper site, displaying partially fractured English, introduces "Dr. Thomspon" in a white medical gown with ...

... no first name, no M.D. after his name, no stethoscope around his neck, no professional identification whatsoever (no information if he is a G.P. or a specialist), no medical qualifications or credentials cited, no certificates on the wall, no hospital affiliations cited, no details about his medical practice and no clinic location ...

... with a company that has no address, no telephone contact number, no email address, and that provides no information about where their zappers are made or shipped from.


Behind the name ...
there is no "Dr. Thomspon"

And when "Dr. Thomspon" appears on his site and in his video it is not in a doctor's office, a hospital, a clinic or any medical setting -- but in front of a plain green screen with no visible identification.

In his video, "Dr. Thomspon" talks about giving zapper treatments. But The Medical System classes zappers as unapproved devices. Doctors know they are prohibited from recommending unapproved devices such as zappers to patients -- let alone making or selling them.

In such a case, their license to practice medicine could be revoked, and likely would be revoked. License to practice medicine? Who needs a licence when you have a white coat? I wonder ... are there any red flags waving in the breeze by now?


Over here ... I have a red flag

But these minor details did not prevent "Dr. Thomspon" from giving an (unwittingly) comical video performance, in partially fractured English, where he appears as the only "doctor" in the world ...

... who refuses to identify himself. He conspicuously avoids a normal introduction like "My name is Dr. [first name] Thomspon from [name of city] ...". He doesn't even state the country where he is located, never mind the city. He introduces himself simply as "Hello there".

Any evidence that would prove the identity of "Dr. Thomspon" or that would identify or locate his company is not only conspicuously absent from his website, but also from the entire Internet. "Thomspon" & Co. are invisible -- intentionally.

Because "Dr. Thomspon" is not a doctor. He has no patients. He is a con artist trying to entice people into believing a pack of lies. His story is a scam, a total fabrication -- including his list of claims for 39 serious conditions that was created off the top of his head ... without a shred of evidence in support.

Support? "Dr. Thomspon's" Supremely Feeble Zapper produces a laughable output of 5 battery volts that discharge to zero. While copying text word-for-word from my site he avoided the part about The Ultimate Zapper producing 9 and 12 constant (non-discharging) volts delivered by Universal AC adapters.

Supreme flexes its
5-volt muscles

In fact, "Dr. Thomspon" avoids the 12 True Features entirely. Because Supreme doesn't have them. But this has not prevented him from boldly declaring that he makes "the most powerful zapper in the world" and was "voted #1 zapper in the world".

I wonder when this "vote" took place and if The Ultimate Zapper was on the ballot? Never mind. At least "Dr. Thomspon" is consistent. His fraudulent identity is mirrored by his fraudulent claims.


You mean ... you're calling me a liar?

Whoever "Dr. Thomspon" really is ... the law will likely catch up with him eventually. I imagine the anonymous "Dr. Thomspon" is looking over his shoulder. I wonder if this keeps him awake at night?
