This was the first Powerball I tried. Really is as good as people say it is, and a must have gadget for all in my opinion.
Only took me a few tries before I had it spinning. Technique is the hard part to master. Outer rubber band which provides grip can rub against your skin but practice and time soon helps with that. Once it was up and running I was suprised just how much it works the arm, wrist and even hand. One minute using this is like 50 or more squeezes with a hand grip. Might or might not have the same muscular effect but it certainly feels the same. Anyway that isn't what this product is about for me, I am fortunate enough not to have any problems associated with my lower arm - Powerballing is said to help with such problems. For me this is about having fun. showing off and being competetive.
This Classic model doesn't have a counter so for this reason I would recommend one that does. Like the Pro models. It's more expensive adding a digital counter later, and that for me really finishes this great product off. It really is good to know you are improving your rpm. And if you want some cool lights on top of that go for a Pro Neon.
I was going to give this 4 stars because it has no counter but that is kinda the point of the Classic model - plus the option to add one later. Easy 5 star.
