No issues with the brace itself, however the product image and instruction sheet in the product box have an error. Both the online product description and the instructions http://www.hely-weber.com/images/stories/instructions/3848_i-
fu.pdf say that you need to order the opposite hand brace for radial gutter.

I did so and found that it is the Boxer's Fracture / Ulnar Gutter (constraining the ring & pinky fingers) for which you need to order the opposite hand brace in order to use it NOT the Radial Gutter (constraining the first and index fingers). I need the brace for ulnar gutter application to an injury of my right hand and ordered right right hand brace, however, it can't be used that way on my right hand (the brace's curve is shaped the wrong way) but it fits for ulnar gutter just fine on my left hand.
