This is the second time I bought these things... First time I bought I didn't use for a few months, when I went to use it nothing happened and Tile cus.services said battery must be dead.... Re purchased 2 brand new tiles for use on a holiday with kids (3months ago) - each time I went to find them it said 'tile out of range' and I gave up. Just found one in a bag and out of curiousity wondered if it would work - had to update the app aaaaaaand 'tile out of range' for both. Pointless rubbish.
