Powerball Pro Plus Gyro - Hand Exerciser, Fitness, Speed Meter

The ultimate in engineering design, featuring the same user friendly features as the powerball pro plus but incorporating an onboard generator and balanced rotor. By activating the gyro a dynamism (motion) is created, which will activate led lights located in the interior of the gyro. It features a balance rotor and removable top cap, which allow insertion of the optional digital speed meter. The powerball generates 40 pounds of torque with speeds up to 14,500 rpm. The faster the unit runs, the brighter the lights will be until your whole hand is engulfed in a bright glow.
