The Supernova Pro is a finely-engineered, high precision gyroscope consisting of a rapidly spinning rotor encased in a solid outer sphere. The faster the inner rotor spins, the more resistance it generates. Powered solely by your wrist and forearm, the Supernova Pro helps drive enriched blood flow and strengthen the entire kinetic chain of the arm from fingertip to shoulder. The built-in LCD speedometer at the top of the ball helps capture the rotor speed to show your progress.
Spin Supernova fast for 60 seconds, and you'll build rapid grip, wrist, and forearm strength with up to 35 lb of focused isometric resistance—helping bring significant benefit to sports such as golf, tennis, baseball, climbing, cycling and martial arts.
Spin slowly and Supernova's gentle, non-impact resistance at low speeds drives oxygen enriched blood flow throughout the arm to gently rehab upper limb conditions, strengthen bones, and improve muscle endurance and strength in the hands and fingers. This can even lead to greater play dexterity and precision for instruments like guitar, piano, and drums.

The ball itself is 'wrist powered' (ie, you spin the rotor by rotating your wrist) so the main movement requires no motors or batteries, it's all done by you.
The LCD display requires two small batteries.
Yes, the sphere's shell is sufficiently small in size to allow it to be efficiently used by persons with smaller sized hands.
Additionally, the rubberized grip band (which runs around the entire circumference of the sphere) greatly assists the fingers in establishing a nice firm grip during use.
