I just found I might be the few user of this new products out there. I can tell you it works as promised but the location is not as accurate as you would expect on your smart phone. It will send you notification through SMS when you arrive the baggage claim belt and you can actually use Bluetooth to know whether your luggage is coming out or not. My only complaint so far is the time of receiving notification varies (sometimes I got the notification when I'm leaving the airpot) and it will not function if you are in a country that don't support GSM network, like South Korea or Japan for example.
