Sorry MH, I don't believe you because I know the zapper works wonders, at least mine does (Silverado Deluxe). I have seen many people helped just with the zapper alone. Maybe not the ones that you sold but definately the Terminator 2 and the Silverado. My understanding is they create more alkalinity NOT acidity. What is your real name please and your credentials. If you claim to be teaching Hulda Clark then it is only fair that you share this information with the folks on this forum who are trying to get healed and learn more about health.
