Re: Of course they do...

>- How do you know that this specific electric signal has managed to kill fungus

I have observed this under microscopic observation as well as in petri dish samples.

>- in a human body ? In all parts of the body ?

Sorry, no claims made.

>- How do you know that using more "positive" electrodes than "negative" electrodes improve the killing effect ?

I have observed this many times after trying many different combinations.

>- Have you seen organisms die more quickly ?

Absolutely!

>- Vagueness as often.

No, it is not vague. Users do not always have success against all forms of related microbes.

I have never claimed that zappers are perfect or that they kill everything.

>- a little more of stealth marketing ?

No stealth to it. The video is a good rebuttal to the BS offered by certain detractors.

Personally, I think that it is great that a customer will spend several hundred dollars buying products and then voluntarily post such positive videos and comments about the products.

There are over 25 customer produced videos at http://huldaclarkparazapper.com/cgi-bin/cart.cgi/videos.html?id=LXb3QphB

We had no control or input over what was said by this user who has tried many different zappers, including Beck and some others that you mentioned in your posts as possibly being best zappers but he rates every ParaZapper product that he has tried above any of those that you mentioned.

In fact, his latest zapper video proclaims ParaZapper MY3, World's Best Zapper
