frequency generators and frequency specific generation devices are Class 1 licensed medical devices in Switzerland and Germany, as some of the Beck devices were classified as medical devices in Canada, but not your GENERAL ONE FREQUENCY "ZAPPER".
I see the F.D.A. agrees with that in a sense...
and it echoes what I have said over and over in many posts throughout the months, reflecting my PERSONAL experience - general zapping is NOT effective as FREQUENCY SPECIFIC zapping, and the zapper sellers here on this forum ignore all that largely, as well as Dr. Clark, and other Dr.'s STRONG recommendations to follow other protocols and supplementation, cleansing, testings, etc. in tandem with any frequency pulse treatments, etc.
