Review: Glad I purchased this one! - Originally, I went by the instructions to measure across the knuckle for the brace. I ordered a Small/Med & it was too small. It cut the circulation off in my thumb. I sent this back and ordered a Medium, which fits perfectly. The strap that fits around the thumb adds a great deal of stability and there is no hard metal in the brace. I personally like this because it's soft yet stable. I wear it only at night right now because I recently had a cortisone shot, which alleviates the pain totally, for 3-4 months. My doctor and I talked about surgery, which would be a permanent fix, however, the down time would be significant - 4 weeks of complete disuse of left hand, (I'm left handed). Plus 4 more weeks of very little use. Complete healing would take a total of 1 year. I was all for it in the office, however, have reconsidered since I've read all about the surgery and down-time involved. I think the brace will help with delaying the cortisone injections.
Review: Support with comfort - I have arthritis and Raynaud’s in both hands. A flair up started as pain and weakness in both thumbs and wrist joints but while the left remained a little sore, the right progressively got worse and eventually the thumb triggered before that joint froze. My chiropractor was able to give me some relief but recommended I see a hand therapist to regain movement. My “bad hand” is improving considerably, but when I told my hand therapist my “good hand” was getting sore from over use, she had me try on one of these braces for size. She recommended I get this specific brace in the correct size to use on the overworked hand to give it support. She said the material will be warming on those joints, and the tightness can be adjusted so it wouldn’t make circulation worse with my Raynaud’s. She was so right It is the most comfortable brace I have ever had on. The material warms my wrist and thumb, gives it strength that I had lost, and adjust to fit all around, so on days my joints are swollen it is never too tight. I am going to buy one for my “bad hand”. Other braces I have tried (several) have been too tight or restricted all movement. With arthritis and Raynaud’s if my joints stay still it is much more difficult and painful to try and move them. I am purchasing one for my other hand.

### ⭐⭐⭐⭐ maybe I should have ordered both sizes and returned one .
*by C***. on July 21, 2026*

I should have ordered a large. This one works okay but fits a little too tight. Easy to use and has great support.
