I have had good luck with them for several ailments. A friend's dad was one. My friend said there were 2 kinds - good ones and bad ones. The bad ones went to seminars where they taught you how to squeeze money out of people. They usually used the "thumpers", he said, which according to him were useless on the back. His dad fixed my neck when 7 rounds of physical therapy at the doctor's office didn't touch it.
