LED Wrist Ball Trainer Gyroscope Strengthener Gyro Power Ball Arm Exerciser
Par un écrivain mystérieux
Description
The unit did not have any weird vibration to it. You can attach it to wrist strap, if you are really concerned about the gyro ball flying away. The dominant hand/arm was easily able to keep the gyro ball going, that it will help refine your fine motor skills in that non-dominant hand/arm.
