## Customer Reviews

### ⭐⭐⭐⭐⭐ Great brace...needs ample time to break in for proper fitment.
*by S***Y on July 24, 2020*

When I first got this brace, I had trouble putting it on. And it was extremely uncomfortable. It seemed to be way too small, however, when I had ordered it, I was very careful to measure my leg for proper fitting of the brace. So I would only wear it about 5-10 minutes at a time. At one point I gave up and chunked it into my closet. A few weeks later I dug it back out and decided to try again. It took far longer than I had expected for my brace to finally conform to my leg. It took nearly a month, but the brace has finally broken in and actually fits my leg ALMOST perfectly. The lower part of my brace actually needs to be quite a bit longer, as I have really large, powerful calves that cause the lower part of the brace to fall right where my calves are at their widest. As such, even when I’m standing upright, the lower part of the brace is angled about 10 degrees backwards to accommodate my calf muscles. This brace works best when worn as tightly as possible. At first it felt like my leg was being put into a major clamp, but once it broke in and conformed to my leg better, it became far more comfortable to wear. Now I’m able to wear it throughout the day. It’s eliminated nearly all the pain in my knee. I’ve worn unloader braces in the past, as I’m a retired Navy Veteran. Ship’s steel decks are really hard on the knees, causing the cartilage to wear away quicker than it ever should. This brace is both more comfortable and provides better support than those braces did in the past. I’m glad I didn’t give up on it.

### ⭐ Terrible Product
*by A***R on September 14, 2024*

This brace took over 1 month to ship and receive for my son. The intentions for this brace was for my son to wear during football season for his weak knee. No where in the description of this item did it say for light use. The attached pictures (3) is what it looked like after using it for one game. The covers for the pivot were plastics of which both broke completely off during his wear. By that happening it exposed the bolts on each side. Product is poorly made. Don’t waist your money. I am very disappointed.

### ⭐⭐⭐⭐⭐ Good quality, helps with pain/support
*by A***R on April 20, 2019*

Have used this brace for about a month now. Fits well, adds stability and decreases pain. Works for both medial and lateral compartment arthritis, the compartment "unloaders" adjust nicely & are slotted so that when the knee is bent, the pads stay in place. Tried placing a cloth sleeve under the brace, but works best with less slipping when applied on the skin. Allen wrench, & extra pads are included. Is well constructed and some thoughtful engineering went into product development. Would definitely purchase again if needed. Believe I can get another year before knee replacement.
