Here we have a quick tutorial from Rory at RPM Power showing the correct start and spin technique for new electric start Powerball e-Titan.
Powerball e-Titan is one of the world's most efficient wrist, forearm and grip-strengthening devices. With a solid zinc rotor capable of reaching spin speeds exceeding 21,000rpm with zero vibration, new e-Titan can generate over 60lbs of gyroscopic inertial resistance and will build muscle and endurance in the upper limbs like nothing else on the planet.
Powered by a lithium battery that drives a patented new electric start mechanism, e-Titan is self-charging and totally self-contained - just press the on button, wait 10 seconds and start spinning!
