I lent a zapper to my friend yesterday morning . As I said he had a badly infected molar abcsess with pulsating pain shooting up into his head. I asked him if he would like to try the zapper as a little experiment to see if if would help to get rid of the infection and he said "at this point I'll try anything". I saw him last night and he was smiling in amazement and said, " the pain and swelling are 80% gone, this is awesome! ". I was a little shocked myself to hear that it worked that fast on such a severe condition, but there you have it folks. The zapper really does work!
