Tile
Look what we got as a Christmas present at our company !! Tile!!
I wanted to buy it some time ago, so checked, thanks STRV:). It works on a Bluetooth base and you can use it for finding the car, keys or mobile.
It is a tiny square, I've decided that I will put it on my keys, because that's the most neglected thing I have.
It is necessary to download an app for the tile. The app will show you how you can use it. Whenever you are looking for something attached with a tile it will make a melody/beep. If you are looking for example for a mobile, you need to click on the E, on the logo.
It is a great gadget and I will maybe buy another ones to attach it to more of my things.
