Sorry but I didn't find this helpful at all. It provided non valuable minimal repetitive information and was about 4 thin pages. I'll do my own research trial and error in the Hope's I can get some positive credit union results.

I’ve been having knee pain for the past few months so I decided to try this support brace. I can’t believe how much support it does provide and my knee pain has gone down significantly. It’s slim so you can wear it under pants while at work but also looks fine with shorts. So glad I found this and it is helping with my knee pain!
positive

Used it as intended on my heels for cracked skin. It would not stay in place on my heel and kept rolling up and off. I would not recommend it or bother using it again.
