I bought one of these, brand new in box, from a previous SD deal. It sat around for maybe a year and I just placed it on my keyring. The 1 yr CR2032 battery was dead (of course) so I just installed a brand new one... which is super easy to do on this model. It's really nicely made, and the app is fairly slick as well, so I went to look what it would cost to buy another and just stumbled upon the Tile.com outlet deals. There are a bunch of different styles on sale... open box and no box. The fact that they give you 2 day free shipping as well, just seems to be the cherry on top.
