Well, I don't have the deluxe zapper. I just have the small one. From my own experience, I think the most important thing my zapper has done for me is--- the day I developed a sore throat. I posted here at curezone that I had a sore throat. John C. (another poster) told me to zap and I did. The nest day the sore throat was GONE and did not come back.
So, I know the zapper kills germs!
If you know you have parasites, (and you are probably right--just about everybody does) have you done a parasite cleanse?
