Parazapper- get off this forum! Beck said that Clark Zappers don't work and yet different versions of them are all you sell. And you're such a scammer! You zap and kill algae in water and offer that as proof that your zapper is effective against viruses and baceteria! Dr Thiel proved that Clark Zappers don't kill microbes. (click here) The most they do is boost immunity a little. And yet you offer his research paper on your site as proof of your zappers effectiveness! such a scam. But people dumb enough to believe you probably deserve to be scammed.
