This is actually the piece of equipment to remove my cast. It vibrated mightily and was very loud, but it did the job. Now I switch to a brace for my arm and frankly I think I would have been better served by going with the snug-fitting brace instead of the not-tight-enough cast.
Glad you are out of your cast! When my kids had broken bones (way to often) the saw to remove it always made me nervous. Good luck on the next step of your recovery.
