  • Not as good as Co. claims this product is etc.
    ValerieJul 12, 2026

    Not such great support, uncomfortable but tolerable; sems like this brace is same as all the others (like this hinged model); sizing not accurate despite measuring %26 getting "correct size" according to their measurement guide for sizing. purchase at your own risk %26 maybe it will work well for you, maybe it won't work for you at all (if doesn't work, it's your money thrown in the trash). Unsure if able to return this or not (read in review, one customer wasn't able to return for refund -reason for return, it was wrong size), unsure if can be refunded for this item either. It was relatively good price considering these are so way OVER priced (no matter where you buy it) -despite same exact quality. Definitely NOT worth the ridiculous over pricing AT ALL. If compelled to buy this--shop around for the best price--yes their pricings are ridiculous .

    Great support would recommend

  • Great value, durable

    I've been using this for about 6 months. I bought it to prevent sideways movement of my knee. It works great at that. Originally a backup for my prescription brace, but now my go-to. The brace is a tube that slides over my knee and tightens with Velcro bands. In my situation it's a little tight- I was right on the margin of size M and L and opted for M, should've gotten L.

    great support but fit is just off, difficult to get on the leg. need open wrap design.

  • Will buy again if needed

    I have used Mcdavid products for a couple of years. These type of braces are a lot better than anything is just compression as they provide more support.

  • RobertMay 3, 2026

    The brace provides great support and I'm pleased with the way it fits. I have a torn meniscus and I'm waiting for my surgery to happen. Good quality and good price and it has 2 straps for tension. Easy to use and start the day.

    Very good brace. Just a tad small for me. I have larger knees.

  • Strong and durable brace for plus size woman
    SUZYDec 31, 2025

    This brace is a life saver. I would have been afraid to trust my knee not to give out without it. I weigh 300 pounds and this brace helped me feel secure while strengthening my leg muscles, and made it possible to continue working. I sew for a living, and I am very impressed with the construction.

    This is my 2nd purchase of this knee brace over the past few years. They do exactly what I need them to do to help protect my knees from further injury.
