RoboKey Motorized Drum Key without Batteries!

It's the only drum tuning and maintenance tool of its kind. More speedy than a simple T-wrench, crank or ratchet, the patented RoboKey increases every turn of your wrist into FOUR turns of the bolt, taking the frustration out of removing it and making drum head maintenance easier. It works in both directions. To remove a bolt, loosen it slightly, then hold the GearDrive with one hand and turn with the other. The bolt is zapped-out at 4X speed. That's it! Designed BY a drummer FOR drummers, RoboKey has no adaptors to lose and is built for a lifetime of rugged use.
