This product helped me with my shoulder pain which was caused by an injury I had from lifting heavy weights at work for many years. The device allows you have more control over how much pressure it applies so there are no worries about causing too much damage or not enough either. It can be used as often as necessary but should only take 30 min max per day (if needed) before resting again until next use. There really isn't anything bad i could say since this worked perfectly well for me. My shoulders felt better after using these devices than they did just wearing normal clothes without any help!
