For me, copper infused products like this one really do work - when I am able to get them on. I am a plus sized gal so my everything at the waist and below is larger. The products simply don't fit, and when they do, they won't stay. The gel at the top of the brace works the first time, and would probably continue to work if I could just leave it on all the time, but that is impossible with bathing and such. They impact circulation on the back of my knee as well. When they actually fit and work, they are a gem!
Bottom Line: Yes, I would recommend this to a friend
