Editorial Reviews:

The Dyna-Flex Powerball Gyro powers up with the rising pitch of an F-18 fighter - with no batteries, no motor. The ultimate in engineering design, Dyna-Flex Powerball Gyro generates from 32lbs to 35lbs of torque when speeds of 9,000 - 13,000 RPM's are reached. A new "thermo band" aids the user in controlling this powerhouse. The Dyna-Flex Powerball incorporates LED lights and an on-board generator. By activating the Powerball Gyro, a dynamism (motion) is created, which activates the LED lights located in the interior. The faster the Dyna-Flex Powerball Gyro runs, the brighter the lights will be until your whole hand is engulfed in a bright glow. Once you give it a try, you won't want to put it down! Great for golfers, tennis players, bowlers, rock climbers and any sport where grip strength is key. The Dyna-Flex Gyro Exerciser made the cover of Time magazine as one of their top 10 digital devices of 2001. It has been featured in numerous articles in magazines such as "Golf Today" and has been awarded the PGA Partners Club "Tested and Approved" seal-of-approval.
