A new wallet? Not cheap. A new phone? Even more expensive. The gift of never misplacing your keys again? Priceless. Consider giving your favorite forgetful friend the Tile tracker, which uses Bluetooth technology to pinpoint where your keys, phone, wallet, or any other item to which you choose to attach it are hiding. Simply press a button and the Tile will emit a sound to help you locate it, or you can see where a Tiled item is on a map or view its last known location. Your grateful friend will never have to stress over lost valuables again. Available on Amazon; $25.
