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 circulation 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.Will it be suitable for a woman's hand?
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.Could this help with carpal tunnel?
Supernova's non-impact, progressive resistance is a fast, effective, and highly efficient way to treat Carpal Tunnel Syndrome by stimulating collagen healing/oxygen-enriched blood flow into the region, enhancing synovial fluid production in the tendon sheaths, and increasing the general range of motion in the joint area; all of which help to reduce inflammation in the [affected] tendons and take pressure off the median nerve as it passes through the joint with the obvious healing benefits that this will bring to the condition.Where can I get replacement cords if one breaks or lose it?
10 x starter cord replacement packs are available for $3.99 on powerballs.com, albeit you can also easily make a replacement cord directly youself by simply getting a 12" piece of wool (or light string) and either melting the tip or tying one or two tightly pulled knots at the very tip. Either option gives the end of the cord sufficient "stiffness" to secure into the hole in the rotor and "grab" it during the starting process (the supplied cords have those little hard plastic tips at each end as you'd normally see on a shoe lace).Do you need battery power for the LED lights to work or just the kinetic spin?
The LEDs are induction powered from the spinning rotor - the faster you spin, the brighter they glow!Does it make a difference which way you spin it?
Whether you spin clockwise or anticlockwise, right handed or left, it is immaterial; the four main muscles in the forearm (which bring mobility and grip strength to the wrist, hands and fingers) are all activated and will respond with an increase in both strength and endurance.
