pain free

These braces are working very well for me. Because of the design and size they do not limit my ability to preform all the aspects of my work. I'm wondering if it is in the rules of golf if I can wear these while I'm playing?

Excellent support

Replaced old cumbersome support brace; much lighter without giving up any support.

Brace works great!

I have arthritis in both thumbs, and had trouble opening doors. This brace really helps!.

Could not wear

I was not able to wear the brace I ordered. Maybe it was to large I do not know but it would rub against my skin causing discomfort. Very disappointed!

Comfortable support

Works great. Much better than larger brace that extended down fore arm. Could even put stretchy winter gloves on over it. Ordering second one for sister. For me though even though I measured to a siz small I had to return and get an XS for a more firm fit.

Great product!

I have arthritis of both CMC thumbs, and this brace lets me turn door knobs. It might not sound like much, but it's pretty iimportant to me!

fine except shipping cost

The brace is fine, the first one I ordered was too big so I had to send it back for a smaller size. I don't think if you exchange an item you should have to pay to send it back and receive a new one. The brace is fine, Velcro does rub a little .
