I'm sooo sorry, (and I'm glad you made me surch through my copy of The Cure For All Diseases to find this) I honestly got my facts wrong :( I really and truely thought she said the zapper WAS "100% effective" when she really said (this time I quote from the book) pg16 "So zapping is still not perfect, but can bring such manifest releaf that everyone should buy one or make one. Parts cost less than $25.00; The plans are in the next chapter." Anyway, glad to have cleared that up. Sorry, I was only trying to enter into the conversation and I hope I did no harm. I'll see ya later then. Many appologies again.
