A woman in my area has a magnawave. Not the mat, but one with long tubes that drape over your body. It's quite a large unit. She bought it as a business, to provide mobile service to horses. And for one of her dogs- she said it cured her dog of cancer, and other people bring their dogs to her for treatment. And of course for people who request it. I think I paid for 10 sessions. The effects were not immediately noticeable, but over time it cleared up a lot of skin issues. This was welcome and wonderful, but unexpected. I had signed up hoping to reverse T1 diabetes. (Nobody recommends it for that as far as I know, but I wanted to try. It seemed to lower my insulin requirement, but it's hard to be sure.)

Since then I bought a smaller unit (with a handheld paddle, not a mat) from Sota Instruments. I'm afraid I don't use it regularly, so can't say much about it. At some point I'll get it out of my closet and into my daily routine. But I've used it enough to say it certainly didn't hurt.
