I'd never stick one of these clunky beeping remote finder devices on any remote I gave a damn about. But they are triggered by the tone of the included whistle, which gives you and your clicker a relationship not unlike Lassie and Timmy. Very cool, until you lose the whistle. $18. Bonus: They've got a keychain version with a flashlight and voice recorder, too. [1ofakind via Crunchgear]
