Numerous Rife machine companies have come and gone since we started. Whether they were well intended folks or not, their failures reflect poorly on the technology as a whole.
The user gets the flu, and pulls out their Rife Machine after not using it for a while. They can’t remember what to do, and the manual is nowhere to be found. They have to resort to an internet search only to find the company is no more.
This happens all the time. It does not necessarily impact the credibility of the technology, many users are satisfied with their machines if it meets their expectations, which doesn’t necessarily need to be particularly lofty. But if they can’t use their machine it is worthless.
