I have had other hand strengtheners before, the one with keys, the one with a spring (in a few different forms), and this is better than all those. For one, it is round, so it conforms to the shape of your fist better. Other ones put a lot of pressure on the heel and fingers exclusively. This distributes the pressure over your whole hand. Plus it has flexion. The one failing is the rubber bands. They are square, and they easily get nicks from the plastic edges of the stays when inserting fingers, which quickly turn into tears. This could be solved with tubular rubber bands. They are also hard to put on because the closure is very tight and unforgiving. Pros: Comfortable, works more muscles than others. Cons: Bands break pretty frequently, and are hard to put on.
