I have the bandage at night off and not so strapped - I had no problems, that it pinches a bit but I've tried only 2 nights, partly I wear them during the day and also feel that they are much too tight between thumb and forefinger is. I am aware of the size L / XL does not but I would have to prefer to buy these.
From Material ago it is processed very valuable but time will tell whether it will remain so.
Stability is good. Some getting used to when writing on the computer - but goes.
Go for bike or other sports activities where you have to include something it is not suitable and probably not intended.
Previously I had a professional bandage but because you could not fasten the Velcro fasteners as well, ie the gutter closure and but the two smaller overlapped there was a better thumb freedom - but this bandage also looks terrible compared to this Greenline.
A return of the price, performance and effort is not worth it, that'll keep you and possibly order the next largest. Too bad that the S / M sizes are not two separate sizes.
