I am still waiting for a serious experiment which demonstrates that adult parasitic worms can be killed by your zapper.
The testimonials you are talking about are mostly vague or not objective, so this is not a big loss.
Objectively demonstrate that your device is efficient to kill parasitic worms/larvaes in all parts of the body (or at least all adults which cause annoying symptoms) and i will help you.(i am not afraid of the FDA, i have not much to lose...))
