Dynaflex Pro Gyro
Can you hold onto this? The DynaFlex Pro Gyro is an executive relaxer...a pulsating buzzing wildly exciting gyroscope...and most especially a serious hand exerciser. Give the gyro a quick pull to start it moving. Rotate your hand so it begins to race and hum. Then hang on! The gyro will try to leap from your hand as it builds to a maximum of 13 000 rpm and generates up to 35 pounds of torque! Gives your wrists grip and arm quite a workout.
