I've had an achey knee for about 2 months and it was definitely getting worse to the point where I was going to go see the doctor. I bought one of these as an interim fixit......I wish I'd bought one sooner, it completely tightened my loose knee and the aches have gone and I can now sleep at night....I bought three of them and gave them to friends with the same ailment....haven't heard back from them yet but I loved mine. I don't need it now by the way but when I'm just chilling I put it on just because it's comfy!!!!
