Dyna-Flex Blue Gyro with Docking Station

Carpal tunnel syndrome, arthritis, tendonitis, tennis elbow, and other repetitive strain injuries can be prevented and eliminated with this handheld gyroscopic exerciser. When you use the Dyna-Flex Powerball Blue Gyro, you get all these healing benefits in a translucent exerciser that glows steadily brighter as the gyro speed increases. A push of the button on the docking station activates the gyro. Then, the motion of your wrist and arm makes the LED light glow brighter blue as the internal unit reaches up to 18,000 RPM while generating 40 lbs of gyroscopic force.

3" diameter; Docking Station requires 2 AA batteries (not included).

Lifetime warranty.
