Lot of fun - really works,
This review is from: Powerball Neon Pro (Sports)
At first this looked like a real gimmick to me - but got one as a gift and it turned out to be both great fun and a good workout.
Ideal for any sports requiring grip/wrist/forearm strength.
It takes a good bit of practice to get the most out of powerball, but once you have the gist of it, the force generated is remarkable.
