Hi John, Thank you for your reply. I must say you have got me interested in this “Zapper”. Do you happen to live close to northern New Jersey or know someone that has one who lives by me. If anyone lives close to northern New Jersey who has a Zapper I would like to try it out on my health problem. Otherwise I am going to have to try and see if my step dad will buy me one and I don’t know if he can afford it since he is always buying stuff for my mom’s phybromyalsia however you spell it. Thanks again John, Daniel
