### ⭐⭐ 







  
  
    Too stiff, doesn’t conform well to knees.
  

*by R***D on Reviewed in the United States on July 24, 2021*

The material on the face of neoprene is too stiff and doesn’t conform well to the knee so I have to adjust these a lot during workouts. It’s almost like a carhartt type material but stiffer.  They slip down pretty easily. I thought it would loosen up and get better with use but I’ve put these through the paces and they have not confirmed any better and I’m still having the same issues. That being said I could see these lasting a long time since the face material is so tough and the stitching is great.

### ⭐⭐ 







  
  
    Did not fit as expected
  

*by E***E on Reviewed in the United States on July 26, 2019*

Very disappointed in what I received today. These knee sleeves look amazing and I was drawn to them because of their look. Unfortunately what I received today was not what I expected. The thigh opening (top of the sleeve) is barely larger than the calve opening. So when I’m in full squat or sitting down the calve opening is not completely in contact with my leg. So much so that I could fit three fingers in the opening. I ordered XL based on the measurement suggestions. The reason I gave them a 2 star is because the look is still great but the functionality is not there.

    Check this out.
  

*by M***. on Reviewed in the United States on September 3, 2017*

This product is great. To start off I have tendonitis and Osgood-Schlatter disease. I have chronic pain in my right knee. Other knee braces and ace wraps have not come close to what this brace does for me  I am now able to squat with light weight, taekwondo, and run. I feel the quality is good for price. Easy on and easy to clean. If your interested in trying out the other braces try this one first. My only complaint is the the sizing was off. I ordered the medium after measuring my knee twice but it's not as tight and leaves some gaps. I would have exchanged it but I lost the box and papers with it. So at least I have a goal to try to fill in the gaps. Near perfect.
