Tile Slim | $19 | Amazon

Update: Sold out

Tile is the ultimate device for anyone who can’t stop losing their things, and you can get one for just $19 right now, easily an all-time low for the 1-pack.

If you aren’t familiar, you just slide this thing into your wallet, keep it in your car, stick it in your luggage...anything you frequently misplace, and the Tile app on your phone can ping them over Bluetooth and cause them to beep until you find what you’re looking for. And if your lost item is outside of your phone’s Bluetooth range, it’ll show up on a map automatically any time another Tile user comes into range.
