The Ruisibo Super Gyro/Wrist Power Ball is a purely manual-powered mechanical device that does not require batteries or any power source. It has no electromagnetic radiation and simulates the natural induction magnetic field and force generated by celestial body movement. It generates significant power through the rotation of the wrist and can be controlled manually to adjust the movement's rhythm and intensity. The faster the rotation, the stronger the kinetic energy and force generated, equivalent to the power of dumbbells of different weights. Principle: Using the principles of gyroscope and celestial mechanics, the powerful force generated during rotation due to the law of eccentricity and inertia puts the arm in a state of primary motion.The automatic-start model uses a spring to pull the ball center and rotate it, eliminating the need for traditional starting ropes, making it suitable for beginners and players who rely on starting ropes. Features: 1. The ball's center has been computer-balanced and calibrated, providing extremely high stability and very low noise 2. Special plastic materials are durable 3. The steel shaft is not easily broken 4. The ball shell features a high-quality silicone rubber anti-slip ring, which is exquisite and beautiful 5. Built-in spring, uses spring inertia to initiate the rotation of the ball's center Some product real-shot images: Product neutral color box packaging in English:
