I got one for xmas. It pull toxins from your feet. It goes through a 30 min. cycle. The water turns different colors and there is some pretty gross stuff that comes out of my feet. They are kind of expensive though. My mom used it and it believe it or not pulled parasites out of her body through her feet. They were floating in the water. (GROSS) Anyway, they are supposed to pull toxins out of your body. Anybody else tried this?
