Drum Kit Keychain
Instead of irritating others in a room by drumming an imaginary solo on the table with your fingers, why not use the Drum Kit Keychain instead? After all, it carries half a dozen playable drums with their own distinctive sound, making a whole lot more palatable and authentic to those around you. It would be nice if the device came with some sort of recording facility in order to record down all your thumb-tapping solos in their full glory to be shared with others. Apart from that, it makes for an interesting keychain, and nice to know that you get batteries included with each $7.99 purchase to get you drumming right out of the box.
