"Rife" technology is fine in theory but terrible in practice. Here's why:

1. True Rife technology is lost although some have gotten some old machines to work. We are left with more questions than answers because Royal Rife purposely didn't make public exactly what he did to cure cancer and the other diseases on his short frequency list.

2. Modern "Rife" machines are almost never like the original machines.

3. The "Rife" frequency list has hundreds of frequencies, 99% of which were not from Rife. Where did they come from? Over the years any "researcher" could add a frequency for a disease, however true or untrue it was. There was absolutely no quality control at all.

4. I used to sell Rife machines but stopped because the success rate of my customers was very low.

5. Why try to pinpoint a specific frequency for each of thousands of microbes when Beck has given us a surefire scattergun method that kills or immobilizes all of them? "Rife" technology is outdated and has been surpassed.

As an insider since 1996 I can tell you the only place for the whole idea of specific frequency therapy from "Rife" machines is in the trash. It's all based on assumptions and not on laboratory tests.
The Rife Frequency List has never been verified. Only about 10 frequencies are said to be from Rife but even that story turned out to be bogus.
Sellers of accurate frequency devices (using digital electronics) jumped on this assumption and made propaganda out of it till almost everyone in the alternative health field believed it. But it's just an unproven theory. Rife used a combination of frequencies to make energy fields quite unlike any device available today. If anyone had a chance of proving that theory it was him but the secrets of his device died with him since he was holding out for a buyer of his technology. What I want to emphasize here is that his device was very unlike any of the available devices today and its success was a combination of the frequencies and the unusual type of energy field that the frequencies modified. All aspects of it worked together to achieve results. For todays available devices for almost every single frequency effect there is a wide range of frequencies (as like a Bell Curve) that work. Looking at the patent for the frequency effect of Oscillating Magnetic Fields it says the effect exists from 5 to 100 thousand hertz. Quite the opposite of saying one specific pinpoint frequency is the only one effective. It has a very broadband effect against all bacteria, fungus, and tumors (not deep in the body).
Same thing for the frequencies used with blood electrification. The effect is not truly frequency specific but rather has a broad effect. Different frequencies are available on my Microbe Electrifier not for the purpose of specific frequency therapy but for differences in transfection (the unwanted side effect of the blood cells absorbing whatever chemicals are in the blood).
Every salesman that promotes the single frequency therapy theory that says it is important that each frequency is accurate and unwavering is a piece of human trash, lying to sick people to get their money. If a laboratory test proves that a certain frequency kills a certain microbe then I guarantee you that you can go much lower or much higher than that frequency and also have good results.
There is no proof of what those liars claim, and a lot of proof that the opposite is true.
Yes I hate them scumbags but not because they are competitors but because they are liars, following in the footsteps of one of the greatest liars of all time, Hulda Clark.
