Why you need the Robokey Gear Drive Drum Key:

The RoboKey 4X is a gear drive drum key that increases your turning speed 4 times or more. Without adapters to lose, and constructed of hardened tool steel and machined gears, the gear driven drum key is a handy gadget that will be a standard drum tool for years to come. Robokey is 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, taking the frustration out of removing bolts and making drum maintenance easier. the Robokey geared drum key 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.
