Review title is A superb brace in all regards [SEP] I bought this brace after a fall in which I'd injured my knee, as well as my ankle, and needed to keep my knee completely immobile -- no lateral tuning or twisting at all, and restricted flexing and extension.  It was the third brace I ordered -- the first was not nearly strong enough, and the second sizing was off. I'm so glad I found this one: It's a superb brace -- fine, sturdy stays,plus hinges that let you adjust both flexion and extension. I initially thought that latter feature was something I wouldn't need, but it turns out to have made a huge difference during this first month of healing. (Needless to say, I could not have handled a sleeve-type brace -- the open front/wrap style was mandatory, and made my life so much easier.)  I've been wearing the brace 24/7 -- night as well as day --  for more than a month and it's been my saving grace.  Service has been superb, too: Before I ordered, I measured my thigh, knee and calf; I was on the cusp between sizes, and so ordered up. That seemed like a good idea at the time because it allowed me to wear the brace over my slacks, as well as under -- but after almost a month of continuous wear. the thigh (which was a little larger than I needed to begin with) seemed to have stretched out; I couldn't wrap the upper portion tightly enough and even with the straps cinched tightly, the brace slipped after an hour or two or wear. I wrote the seller and asked if there was a solution -- this brace was costly enough that I didn't want to have to pay out of pocket for a second one -- and they offered to send  me a smaller size. It arrived within a few days, accompanied by a label for free return of the first.  I couldn't have been more impressed or more grateful. I'd recommend this brace, and this seller, to anyone.
