Boy, I know that feeling, since 1996 ive been zapping, starting with copper pipes to a few cheap zappers, then the bio wave which excepts chips, then the varizapper which excepts cards, cured md with this, macular degeneration, when I saw the list of 3000 disease, resonating minerals, brain waves, I new I had to have a programable VariGamma and feel this was the best investment I ever made. If it were destroyed for some reason or other I wouldnt hesitate to buy another one.If you can afford one, go for it, you wont regret it.
