I bought 2 for my husband. He uses them for the fast walking he does every day. He is quite satisfied. They fit well and "hold" his knees steady (he has ligament problems in both knees). The only thing he told me is that he would prefer them to be shorter in length. But, all good. They have been doing their job for about 2 months now.

Excellent, especially for its cost. It fits perfectly, depending on how tight you want it. Excellent compression, while giving you great self-confidence and security. The only "negative" (if I can say that) is that the velcro needs attention to be fastened in its proper place and not randomly on the strap, as it will start to come undone. I use them for powerlifting workouts and I highly recommend them.
