Great Customer Service
Tile works like any Bluetooth device - 10 m range (up to 30 in ideal conditions) - your phone keeps track of when it last "saw" the tile - and records that location. The battery will last up to two years if you keep it in normal environments. And tile offers a replacement programme where you pay less than half if you replace on schedule. The new ones even allow you to use the tile to find your phone (if its within range). And each tile is uniquely keyed so if someone finds your stuff and contacts tile, they will help you get your stuff back.
