The idea: The Cobra Tag lets you call your lost keys the way you’d call your misplaced phone. The tag can be attached to pretty much anything you’re prone to misplace.
It’s hooked up to an Android-friendly app; when you press a button, the tag will start to beep.
Since it’s connected by Bluetooth, it only works within a certain range. However, the second the tag goes out of the phone’s range, an alarm will sound.
You’d have to be really careless to lose your keys with this tool.
Whose idea: Cobra
Why it’s kind of brilliant: Cobra Tag is perfect for anyone who’s prone to losing valuables, but the $60 price tag makes it a little unappealing. It’d be cheaper to buy a new set of keys.
