Introducing Powerball - one of the most unique and dynamic products available on the market.

Extreme Powerball: It's about the same size as a tennis ball and weighs just a little more, but take a Powerball in your hand, set that rotor in motion with the cord provided (or use your finger when you get used to it) and you'll experience an extraordinary sensation
