I can’t tell you how many times I’ve wished I could “call” my keys to find them, just like I do when I misplace my cell phone. Now, that’s actually a possibility (sort of). With Stick-N-Find Bluetooth stickers, you can track and find just about any item using your cell phone.
Stick-N-Find is about the size of a quarter, so you can stick it on almost anything, not just your key chain. You can set it to buzz or flash a light, and you can also have the complimentary phone app alert you when your sticker goes out of range.
