Kirjeldus
Gyroscopic wrist booster with illuminated LEDs. The principle is based on a rotor that serves as a flywheel. It spins with the included cord and the speed of the flywheel is maintained by the circular movement of the wrist. It is used to strengthen the wrists for various sports, but also for musicians (pianists, violinists) and for fun for the whole family.
