Yes you are correct there are good and bad reports. Yes its sad that their are prevaricators and scoundrel's in every business. This is why you have to do your home work. some of the machines do not work period.This is mainly because some of the machines on the market do not have the RF carrier wave.
Pam they have machines today with our science and technology that are better and smaller than the original. You have to do a lot of home work and exhaustive study to know about what you are buying. Like I said they are not cheap so you do not want to throw your money away. The links I supplied you are good machines. Gary Teal in the upper part of the States is a Dr. and right now he is doing some clinical studies among other Dr.;s and Scientist they are documenting every thing. I called the man on the phone and spoke to him quite extensively. He is spear heading the GB-4000 . He even has an original Royal Rife machine. The GB 4000 machine dose work it designed is taken directly from the original. The only thing is if you can afford it a lot of people can't.
I like the F-17 better though because its more user friendly I think. Its is based on the software running on your own computer rather than the machine possessing it. are you having to manually program frequency's into it.
I trust the GB 4000 only because I spoke to Dr.Teal directly. I haven't totally checked out the F-17 I'm calling them Monday to ask some direct questions. If it uses a carrier wave then I am getting it. The f-17 does use a plasma blub. The RF carrier wave can pass through steel so it has no problem passing in to deep tissue and bone even and deep organs and even DNA to nerves. Diseases cant hid form it. It's also painless and quick. Plus it last for decades. Its cheap insurance I think. Last reports it kills over 700 diseases. Click on the Frequency List tab in the link below and you can see all the Original Rife frequencies and the list of what it cures from A-Z.
