Letigo LED Wrist Ball Gyroscope Strengthener Ball Power Ball, New Wrist Gyroscope Wrist Strengthener Power Force Ball Arm (Orange)

Specifications:

• 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. There is a place to attach a lanyard of sorts, think Wii mote wrist strap, if you are really concerned about the gyro ball flying away.
• 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.
• LEDS: 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.

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!
• STARTING: The cords that come with it have a plastic sheath over the ends that help it stay in the starting holes of the gyro's rotor. It comes with a string included to help start the spinning action. if the gyro is to the right so should your hand, follow it and slowly speed it up. It lights up when spinning. The ball is plastic with a rubber grip on it, it's very easy to hold and you not worried that it will slip and go flying into a window or something.
