I finally bought an ampcoil with my last good credit card. Why? Because nothing I tried worked and as time goes on I discovet another layer of parasites. I have trichanomas and flukes and protozoas and pinworms and hookworm and ropeworm, candidia....ugh. So far all I can tell you is I feel better. If you don't purchase one of these devices I'd go with a spooky 2 generator(a lot less expensive).
