This key finder/anything you don't want to lose finder works well. It works so good that you will need to keep it fairly near your phone at all times or it will alarm! lol This is perfect to tag your kids with! lol It shows you the location of whatever is attached to it right on your phone screen. If you get about 100 feet or so away from it your phone will make it beep so you can locate it and if u want to take a picture with yourself in it, u can use it to remotely snap a picture! It is easy to pair through the bluetooth on your phone. This is a neat little gadget.
