017TRAKDOT Travel is better when you know where your luggage is. The TSA-approved Luggage Locator "goes to sleep" when your plane takes off and "wakes up" upon landing. It tells you where your bag is (via text or e-mail), and even when it's headed your way on the carousel. Simply download the free app and pack it inside your suitcase. Works in every country except Japan and South Korea, in all bags except all-metal luggage. Compatible with iPhone 4S and newer models running iOS 7 and higher, and Galaxy/Android devices running Android 2.3 (Gingerbread) and higher. Includes one-year service contract.
