I bought this knee brace for two reasons. 1) I needed a knee brace for bowling/hiking, and 2) I totally believe in the healing effect of the magnets (I have worn magnetic bracelets on my left wrist for about 2 years, and that keeps my extremely painful tendonitis in check). I have used the brace several times now, and it seems to make a big difference. TWO THUMBS UP. The only negative would be that it doesn't seem to be as long as the one in the picture. At any rate, it seems to get the job done, and I really like the velcro closures so I can make it as snug or loose as I need.
