•5-Star Rated: " This device has given me some relief for my wore out knees. My wife used it on her thumb that has given her trouble for over a year and it is 90% better. Didn't really think it would help but when you're in pain you'll try most anything. I'm so glad we gave this a try and have recommended it to several friends and family members. Fast shipping and great case was included, well packaged. ”
