We opted for the 90-minute de ionizer 30-minute treatment plus hour massage. My pan was black while my wife's was orange. The workers really couldn't explain what it meant but showed us a chart. It's all very interesting but I couldn't even find an explanation online except you are supposed to have a sense of well being afterwards. The massages were good my masseuse walked on my back and cracked it. I'd go back for the massage but probably skip the hocus pocus. They didn't use oil or lotion. They must have forgot to tell me people with pacemaker's shouldn't have this procedure done.
