Trivia time! Question: Where does your suitcase go when the airline loses it? If you guessed “The nether reaches of Mordor,” you’re partially right. We think. Point is, we often have no clue where our bags go. But the Trakdot Luggage Tracker changes all that. Just put this AA-battery-powered beacon into your checked bag and keep tabs on its whereabouts via your smartphone. You’ll get real-time updates on your bag’s current city location through your iOS or Android device. It even sends texts if you lack a smartphone. TrakDot itself costs $50, with a $9 activation fee and annual service fee of $13.
