Jumpstart your Gyro Ball!
With a push of the button, the new PowerBall Docking Station activates the gyroscopic Blue Powerball as it reaches up to 18,000 RPM with 40lbs of gyroscopic force.
As speed builds, resistances grows and the GryoBall is ready to help maximize your grip strength.
Blue lights illuminate in the Ball to let you know when it is fully charged and up to operating speed. As you hold the empowered Gryo in your hand, make back and forth movements to increase your strength and help prevent conditions of carpal tunnel and more.
Requires two AA batteries, not included.
