Precautions for Using the Wrist Ball

1. The wrist ball is fragile to falls. Please tie the wrist rope before using it. After use, please place it properly to avoid accidental falls. 

2. Under no circumstances should you hang the ball by the wrist strap. The strap only serves as a safeguard against falls and cannot bear weight. Remember this. 

3. Please don't press hard on the core of the ball to avoid violent shaking after starting, which will easily damage the ball track. This will cause irreversible damage to the ball track and will directly affect the feel and sound during use. 

4. Please don't inject any lubricant into the ball core, as it will reduce the operating friction and directly lead to the failure of the ball's operation. 

5. When the ball is spinning at high speed, please don't touch the core with any part of your body to avoid getting hurt. 

6. Regarding the applicable population, children under ten years old and the elderly over eighty years old are not recommended to use it. If you need to exercise, please use other alternative equipment.
