****ing. A. After five months of recovery, my left ankle basically has zero muscle and I've been setting myself back because of it. I started doing exercises with this thing yesterday and my god does it massively help. My dumbass should've gotten one of these a month ago but I can kind of see the light at the end of the tunnel now. Consider this a PSA in the event that you break your ankle and your doctor doesn't give you much recovery advice.
