“Dammit, where did I leave my keys?” are words that you never need utter again when you’ve got yourself a Loc8tor Lite. Attach a dinky homing tag to your easily waylaid item of choice, and the next time you lose it you’ll be able to search it out using the credit card-sized handset. The Loc8tor uses flashing lights and ET -style bleepy noises to help navigate you to within an inch of whatever you’ve lost, and with a maximum range of over 120 meters, it might even come in useful when you’re trying to remember where you parked your car. Just pray that you don’t lose the handset.

Loc8tor Lite, ¥12,600. Available from electronics stores, Rakuten and Amazon Japan.
