YunMai Powerball Carpal Training Apparatus Wrist Ball Trainer LED Gyroball Essential Spinner Antistress Toy
LED FLASH - The LEDs increase in intensity the faster that you get the revolutions going. At least gives you a general indication to how fast you have the gyro spinning. The blue LEDs getting brighter.
MOTOR SKILLS - This certainly requires some fine motor skills in order to use. 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.
EASY TO USE - Simple to start with a pull-string. Impact resistant structure with military-grade plastic shell. The more exciting part is, this exercise ball lights up when it's spinning! And the LED light is not powered by batteries. It's battery free. No need to worry about power running out. It will keep lighting up as long as it's spinning.
HIGH QUALITY - The unit did not have any weird vibration to it. Also having the silicone grip section is very nice as it helps with the gyro ball not coming loose from your hand. You can attach it to wrist strap, if you are really concerned about the gyro ball flying away.
Note: There will be a little sound when the ball is moving.
- Small, pure machinery, no electric weight loss exercise artifact.
- The operation is simple, follow the arrow to the end, release it to start.
- The wristball changes with the speed of the inner core of the rotor.
- Use special wrist straps for safety and reliability.
- Brilliant lanterns come with light effects that vary with speed.
