Good knee brace
Product itself is good and is easy to adjust. You'll need to experiment with how much you bow the knee brace frame to relieve the pain. I'm starting to feel pain relief now when I'm walking or hiking.

Don joy OA Nano saved my knee
I've been wearing this knee brace now for 3 weeks on the advice of my doctor. My right knee is now completely 100% pain free and that's quite an improvement since I was contemplating having knee replacement surgery at my last doctor's appointment. I used two different knee braces in the past that were bigger, heavier, and bulkier. They constantly slid down to my knee which was a pain. This brace stays in place and I'm very pleased with the results. Now that my right knee is pain free I may need to try getting one for my left as it is starting to bother me as well. Thank you for such a wonderful product that has saved my knee and put the idea of having a knee replacement on the back burner for now.
