Did it's job supporting my kneww
I've only had the opportunity to use this once since I bought it. I originally ordered it for my wife but then decided to give it a go when I started running again this season and was having some pain in my tendons on the outside of my knee.
I ran up Grandeur Peak here in Salt Lake which is about 4,000 feet in elevation gain in 2 miles. Then I ran back down it and felt zero pain like I have been feeling (aside from my muscles trying to fail on me and throw me down the mountain).
Only drawback is that it's really sweaty, and now mine stinks.
