TrackDot

This can save you a lot of headache if you have ever had lost luggage. From the people at Globaltrac, just stick the TrackDot in your luggage and it will let you know where it is. What is neat, is that it runs on just two double AA batteries and will last you 28-days. When moving faster than 100mph (i.e. on a plane) it will automatically shut off and turn back on when it slows down. It runs on the GSM so the Federal Aviation Authority won’t bother you about it.  It even has Bluetooth to let you know when it’s rolling down the carousel. $49.99.
