i was intrigued to see if anyone else used Tile and finally found this thread :-) as people have alluded too, it wont get your bag out any quicker, but for me, it definitely avoids any need to stand waiting for your bag amongst the people who insist on standing up close to the belt for 20 minutes!

Their userbase must be pretty widespread. over '200 users nearby' when i opened the app in heathrow last week. I guess there's a bit of hope if it goes missing, you may see a blip somewhere at some point in time?

I wrote this up on it if anyone wants more info http://triphacker.co.uk/tileapp

it's also a heck of a lot cheaper than the new smart luggage options out there, which on the gadget show a couple weeks ago got mediocre reviews on the features they have!
