I just bought two Treasure Tags. They'd pair via Bluetooth, but the app never recognized them at this time (there was an obvious pairing dialog coming up once for each tag that I paired, but then it was followed by the app appearing to not have found a tag). Turns out closing the app and reopening it was enough; it now showed the Treasure Tags paired. But I have not yet seen any possible way to get a map of the most recently seen location of the tag. I can make the tags play a sound, and vice versa from the tag can make the phone recognize I pushed the button. I couldn't name the tag when I first paired them, but actually haven't tried to do again. The colors were enough. But without a way to bring up the location of the phone the last time it was connected to a tag it makes the tag somewhat pointless to bother with. Actually, even if it all works as advertised, I'm not really sure I care. I just bought the tags to play with. Though I suppose it was amusing to be on a plane and have it actually connect to the tag (and disconnect when I walked into the restroom). I wasn't expecting the possibility of connection between the passenger cabin and the luggage hold. It was moderately comforting to know for sure my luggage was on the same plane I was.
