Absolutely worth the price!
I have been wearing this knee brace for 2 years to do martial arts every week and it still going on strong, so durability is not a problem. The level of support is amazing regardless of how the knee is moving. I had to fiddle around with the straps to suit my needs but they are adjustable so that was easy to deal with. I found I still had about 90% freedom of movement while wearing it, which is excellent considering you ARE wearing a brace and it also has hinges. The biggest positive for me (considering that my knee has no ACL) was that I was confident I could kick, run, jump and twist on my knee without worrying about it caving in or getting injured. I would absolutely recommend this knee brace.
