I got a refund for most of my Tiles well before the one year battery fail because they simply stopped working, and never reconnected. If TrackR bravo works better, great.
Tile stopped offering replacements for Canada, btw; no idea why but they said they stopped shipping here. Given the importance of a crowd-find feature, I can't imagine why anyone would continue to use Tile in Canada now.
First they stopped shipping to Canada, Germany and Italy (while still shipping the rest of the European Union). They now have stopped shipping to anywhere except the US (+ Puerto Rico, Guam etc.). For first roll-back the cited orders taking way to long to arrive in those three countries (I have no idea why Germany and Italy would have been different than other EU countries). For the latest roll-back they have not given any reason, they have not even acknowledged that they did a roll-back.
Unless they have problems with RF regulations, I have no idea why they have stopped shipping to outside the US (ok, maybe they feel unable to deal with any kind of customs).
