This review is from: 250hz Classic Gyroscopic Hand Grip Exerciser Ball for Strengthening Forearm Muscles or Rehabilitation of a Broken Wrist (Sports)
At first I thought the Powerball was a bit of waste of time. It took me a long time to get to grips with how you get the inner ball to rotate. Once you have the hang of it though, it's really quite addictive! The idea is that you hold the powerball in your hand and slowly start to rotate it so that the inner ball spins. Once you pick up speed the inner ball's resistance kicks in and it gives you a great arm workout - perfect if you play a lot of racket sports. Beyond an exercise tool, it's really addictive and I would guess it's a great way of keeping your hands busy when trying to give up smoking! Highly recommended!

Erm, I thought you are supose too pull a string to start making the gyroscope ball rotating at a speed of 2000 rpm or more.Depeding on the force you pull by the hand.And when you rotate it like that then you slowly start moving your grips until you hang it...
