Getting good relief
My doctor said I have mild arthritis and recommend this brace. I've only used it for a week but it seems to be helping. I don't have as much pain with walking and climbing the stirs at my job, and my knee doesn't buckle on me like before.

Using it at work
I have been using the brace now for a couple of weeks mostly at work. The BOA closure helps cinch up the web around the front for a comfortable fit around my knee. Recommended.

Didn't help my knee but ...
The brace itself didn't help my knee pain - probably because my osteoarthritis is more severe so I had to exchange this for the OA Adjuster 3 instead. But it is well made and seems like it would help someone with more of a mild type of arhtritis. DME-Direct customer service was very helpfull with the exchange.
