I really wanted this splint to work! But alas, it did not. I believe that the problem may be the thickness of the pad, which is the part of the splint which is supposed to compensate for lack of natural padding over the trigger finger's tendon. I think that, if the pad was thicker, it might work. I base this on the fact that, when I fold the pad into two parts (so it is double thickness), the splint works better. It's a good design, but needs to be perfected.
Option: Large, 2-3/4" to 3" (7cm to 7.6cm)
