Usage Method：
Step 1 - Intertwine
Hold the ball horizontally with both hands, and alternately push the center of the ball with the thumb in the direction of the arrow until the resistance is maximum and cannot be pushed.
You should feel some resistance building up as you wind up the rotor, like a toy race car. The rotor should be fully wound within 10-15 steps.
Note:
Hold the wrist ball outwards or horizontally, otherwise it will interfere with its rotation.
Do not continue winding after encountering resistance during the winding process, otherwise the product will be damaged.
Step 2 - Release
The thumb quickly releases the center of the ball and holds it in one hand, rotor should now spin at a moderate speed.
Note
:
Don't touch the center of the ball to prevent pinching your hand.
Step 3 - Rotate
Rotate the wrist in a circular motion, feel the centrifugal force generated by the center of the ball, and slowly accelerate.
Be sure to keep a tight grip on the ergonomic grip once the rotor is spinning up to speed.
Note:
When speed increases, the resistance increases.
The higher the speed, the easier it is to operate.
How to stop ?
Temporarily rotate the wrist, and the ball will stop rotating within approximately 30 seconds.
Rotate key points:
Battery free design!
Your hand is the battery of this device. Make sure you start the gyro ball with sufficient speed.
The motion of your hand rotating the gyro ball is similar to making ice cubes swirl inside a glass. The faster the rotor spins, the easier it is to operate.
The essence of operating the gyro ball is about how to synchronize your wrist rotation to the momentum and timing the rhythm of the rotor’s gyration. Not about how fast you rotate your wrist.
Use wrist, not forearm!
