Power Ball (with Speed Metre)

The gyro is an executive relaxer, a pulsating, buzzing and wildly exciting 
gyroscope, and most especially, a serious hand exerciser. Gives the gyro a 
quick pull to start it moving. Rotates your hand so it begins to race and hum. 
Then hangs on!

The gyro will try to leap from your hand as it builds to a maximum of 
13,000rpm and generates up to 35 pounds of torque! Gives your wrists, grip, 
and arm quite a workout. Available with a removable lid for adding speed 
meter. This gyro comes with a removable top cap so either now or later you 
can add a speed meter to check rpm.
