Deta Elis, a Russian company, offers well-being devices based on the research of Paul Schmidt and Royal Raymond Rife, supported by clinical studies and patents. Users are seeking affordable resonance frequency analyzers to test the frequencies emitted by these devices, with links provided for more information. The discussion touches on the controversial history of Rife's technology and its discreditation by the medical community, while some participants express belief in the efficacy of resonance in manipulating biological systems. There is a call for recommendations on instruments that can accurately read these frequencies, with some humorous suggestions like dowsing rods. The conversation reflects a mix of skepticism and belief in the potential of frequency-based therapies.
