If your machine is adjustable in some way ,maybe ok. but if you just turn it on. theres too much miss before ahit. After my 3 friends cured their hep c with a Rife light to the tune of drinking alcohol again which is a major miracle, I took a deep breath and had a long talk with my not spring chicken self & bought one.its kicks the shit out of herpes.I also have a friend who controls his lyme disease with one. I believe if the bird flu deal gets cranked up it will save my life.But it is 5000.00 the life expectancy is 10,000 to 20,000 hrs and it is very sturdy and looks like that much money to me.
