Yes, I am David Etheredge.

What the FDA states in a letter does not always tell the whole story. Like they do not mention that the came in with over 20 officers, carted off our records and equipment, and spent months trying to get our customers to file complaint against us. They also told at least some customers never to contact us again. When they failed to get even one single complaint filed, they had to return our equipment and sent us the letter which basically stated that we had not asked their permission or paid them money.

>- Such as what device was used and why no other Zapper could do accomplish this.

The original test in that series was performed using the ParaZapper CC2 ( initially using mode 1 ) along with a couple of competitors zappers, and a DC battery connection.

Later, the test was repeated with our other models as well as using other modes.

We also tested the CC2 with 7-1/2 minutes on, 20 minutes off, repeat 3 times. This was some better than other zappers but was no match for multiple frequencies.

This basically showed us that multiple frequencies applied in sequence killed a wider range of microbes than any single frequency that we tried.

If Dr. Clark had of seen this research, she might have modified her claim to ( Any frequency between 10 Hz and 500,000 Hz may kill many different microbes but not all, adding any second, different frequency may kill additional microbes that were not completely killed by the first frequency, and any additional frequencies may kill additional microbes that were missed by the previous frequencies ).

She introduced her zapper ( the circuit had been around for about 20 years before this ) as a substitute for expensive, difficult to use Frequency Generators despite the fact that they were much better.

>- another excuse

No, not an excuse, fact.

>- Since not all countries have the same laws concerning alternative technologies and alternative treatments,

Correct.

>- why after more than 20 years, there is still not one convincing proof that a zapper manages to kill parasitic worms inside a human body ?

why after more than 100 years, there is still not one convincing proof that a zapper does not kill parasitic worms inside a human body ?

>- to do the experiments (tiny cameras)

You can stick one where it is required if you want but I do not think that most of these would be either safe or very comfortable.

>- all i see from you are excuses

Perhaps that is all that you want to see?

Again, my issue is that I live in the US and if I were to publish such proof, I would be quickly shut down and arrested.

Again, not looking for testimonials. What I'm looking for is scientific proof.

The Thiel study was a published scientific study and is not a testimonial.

Also, statistics are not testimonials.

Testimonials are useless if the people who post them have no idea what they are talking about...
But they can be a good indicator that something is happening and is worth researching.
