it is the one most often referred to and used. I do have suspicions on some of the frequencies but many have been reported by and confirmed by multiple users.
Ok so the answer is : "i have not made some experiments and measurements to confirm that each specific frequency in the "Rife frequencies list" manages to kill a specific harmful organism".
And : "i claim unjustified things just to improve the image of my devices" (to what end ? guess !).
