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.
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.
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.
