Great product for hand rehabilitation (and continued hand strength)
Having recently had triple trigger finger surgery I was looking for something I could use at home and this is it. The black side is stronger / sturdier than the green side so it gives you a range of workouts. Not just for after surgery, this thing will keep your hands and fingers strong for life. Musicians might benefit from this especially, keeping those fingers strong. The list goes on....100% Recommended product.
