Works quite well. Allows me to use a mouse much better than the full brace from my doctor. Not as good as the full on brace but excellent to allow me to use the mouse or wash it. It comes with spare wrist and thumb straps. But not the thumb and wrist “sock” to help with the abrasion. So once that is wet, it needs to be dried out. Got M when I am supposed to get a S. But I think it still fits well enough. Would recommend it. But wish it came with a spare “sock” to prevent skin abrasion so I can still use the brace if one gets wet and needs to be dried.
