Gina I donīt know much about rife machines but I have been looking in lyme-rife forums where there seems to be many people being cured with rife machines. Some seems to be a bit better than others.
I bought 2 machines from jaguar enterpises years ago and they unfortunately broke after some time, but they were a weak magnetic pulser and a bob beck silver pulser. The pulser killed some organism in the bloodstream where the blood was circulating so it did work and the magnetic pulser I wasnīt sure about. I never felt any difference after using it. After this I bought a very strong magnetic pulser which I had to connect to a car battery from another company that didnīt work either, but could probably work for other ailments. So this bob beck machine donīt penetrate your organs with the frequency, so the infections you have in an organ donīt get killed.
There are other rife machines that seems to penetrate the body better than these devices, although I have only tried one for 2 months at the most and this time was not enough my condition.
