My wife gifted me a Cube Key Finder for Christmas because I'm always losing my keys and my wallet. It works similar to Tile Mate, but with one key difference that I think our readers will appreciate: a replaceable battery. Changing out the battery requires a similar process that changing a garage door opener requires.

Cube works as you'd expect it to. You pair it with your iPhone, and then you can attach it to your keys, wallet, gym bag, etc. If you lose the item, you can ping it from inside the Cube app.
