Dear Wendy
I think your widget is genius.
I used one after a distal radius fracture. I first tried using it shortly after cast/orthosis removal but I found it irritated by TFCC/ulnar styloid due to a concomitant fracture of the ulnar styloid. But I tried it again about 4 months post fracture when I could where it confortably. I used it for lifting weights and weight-bearing activities for several months. It made a great difference in terms of preventing pain during those exercises.
I wish you huge success in your business.
Kind regards
