Dynamic, oscillating roller ball hand exerciser. Develops grip, wrist and forearm. Holding the tennis ball-sized device and rotating your wrist causes the internal gyroscope to spin up to 8,000 rpm and provide up to 12kg of torque resistance to strengthen the wrists, biceps, triceps, and deltoids. Improves your grip for tennis, golf, and other sports. No batteries required.
