THIS IS A BRAND NEW ITEM!

A standard 250Hz Powerball fitted with an RPM Counter (speedometer).

The RPM Counter allows physical progress to be monitored on the Powerball, for strength and rehabilitation exercises. It also transforms the Powerball into an addictive entertaining and competitive device. The current world record exceeds 16,200RPM !!.

Perfect for relieving and treating the symptoms of Arthritis, Carpal Tunnel Syndrome (CTS), Repetitive Strain Injury (RSI), Tendonitis and many other conditions of the arm..... from every muscle, tendon and joint in the fingers right up to the shoulder...

Different  Speeds, Direction and Posture  can  target specific areas or components of the arm to give them a thorough isometric workout. The Powerball is a completely human powered device and the user is always in control. Considering that the rotor can easily be pushed to speeds far beyond that of most electric power tools  it's quite an amazing experience, but its physical effectiveness over a short period of time will astound even the hardened skeptics.
