"I am a forgetful person who loses all of my stuff all the freaking time, especially my wallet. That's where this little device comes in handy. I just slide the Tile Slim into one of the credit card slots in my wallet and can now track where it is with the help of the free Tile app. If I can see that it's in my home on the map, but can't find it, I just ring the device and it sets off a symphony of noises that help me hunt it down." —Alice Prendergast
