Ahead Robokey Drum Key

I actually bought this item on a whim before placing an order, as I needed a spare drumkey. Thought it was an electronic tuning device, but when it arrived, I could see that it was not. It works with internal shifting gears, so no need for battery exchange. I must say that this is a GENIOUS device, that I wish I purchased earlier in my career as a drummer. I play DW drums, and their tuninglogs tend to be quite long. With this nifty gadget from Ahead, I can change the drumheads SO much faster. Only negative thing is that it feels rather plasticky, so I don't know how durable it is in the long run. Time shall tell. I would definitely recommend this to any drummer who hates changing drumheads. This makes it a breeze.
