Odds and ends

The quarter-sized StickNFind buttons, which come in a two-pack kit, attach to anything: the remote, your baseball glove, your daughter. The buttons sync over Bluetooth Smart from about 150 feet. The app Android or iPhone/iPad app lets you create a "leash" that alerts you when the button goes out of a set area. You can use up to 20 buttons per device. They last about a year.
