My wife bought one and uses it from time to time for chronic neck and back pain. I did however try it last week when I had some neck pain from falling asleep in my den watching Wagon Train. It was a short lived relief that day and I tried it again the next day with the same results. But I do think it shortened the time it usually takes to get over this. I have been thinking about using it a few times a week to help my own hip pain. It only takes a few minutes.
