What good is something if it doesn't work? My wife was having trouble with some leg cramps and I bought it thinking it would help. This thing would stop after a few minutes of being turned on. I have had it just less than 60 days. I emailed the company about returning it and they have not replied.Again I ask, "What good is something if it doesn't work?".SAVE YOUR MONEY!
