... I purchased this product since I have been chewing my fingernails for years. I figured if I had something to keep my hands busy, I wouldn't chew anymore. The Isokinetics Hand Exerciser Squeeze Ball worked really well for me this way.
Pros:
+Cheap - if you were to find one of these in a physical therapy store, I guarantee they'd be expensive. Thanks Amazon!
+Extra firm - it seems I will never have enough hand strength for this ball not to work.
+Bouncy - if you get tired of squeezing it, it can serve as a fairly impressive bouncy ball too!
+Easy cleaning - Soap and water are all you need if you're going to clean it.
Cons:
-Bouncy - Although this is a good thing, it's bad too. If you happen to drop this ball, expect to chase after it. For this point, the egg shaped might work better since it would stop bouncing more quickly.
-Black - because it's color is so dark, make sure you know where it is. A few times it's bounced away from me and been a struggle to find since it blends in to dark carpet. ...
