Its advanced mechanism allows for a cord-free start, simply by spinning the ball with your fingers until it is fully "wound up." Once you release it, the rotation begins, which you can intensify by making circular motions with your wrist. As the rotations increase, the exercise becomes more demanding and effective.

The ball is made of durable polycarbonate for the outer shell, while its interior consists of high-quality hard plastic, offering durability and long-term use.

• Material: Polycarbonate exterior, hard plastic interior 
• Starting mechanism: Manual Weight: 0.31 kg 

Avoid drops on hard surfaces to prevent damage to the gyroscope. Do not touch the inner ball when it is spinning at high speed, as overheating may occur. Use by children under 12 years old should be supervised by an adult. Keep the device clean, avoiding contact with dust, moisture, or oils.

Hold the ball and rotate it with your thumbs in the direction indicated by the arrows. You will need to make about 10-15 rotations to prepare it. Release the ball and start spinning it using circular wrist movements. The faster you rotate your wrist, the more the speed of the ball increases and the intensity of the exercise.
