Probably one of the best purchases I've ever made! It even comes with batteries. So you have like 6 little pieces that you can put on things you don't want to lose. Your keys, wallet (it's so small it slides right inside) and we are gonna figure out how to add one to our tv remote. Make sure you put the remote somewhere you won't lose it. It does have a remote holder. When your keys are lost press the button and your stuff beeps whenever it is. Amazing
