Perhaps, one of the best features is that the Tile Mate can call your phone--even when it's on silent! All you have to do double tap on the Tile and your phone will ring if it's within 400 feet of Bluetooth range.

While the traditional square Tile Mates might be more popular with some shoppers, there are three other styles you can choose from. In fact, Tile recently released a new smaller Tile called the Sticker. The Tile Sticker is great to stick on smaller electronics and has a built-in three-year warranty battery.

One review praised the sleek designs of the Tile Slim and Tile Sticker: "Really great products, I've got a couple of their older models but wanted to add the new Slim and Sticker to my collection! They work as great as usual, longer range apparently too which is good, but I love the new designs - the Slim fits perfectly in my wallet and its much louder than the previous version so I can hear it a lot easier now when I've left it in the laundry basket (!!) - sadly that also means the Missus can find my wallet easier too..! The Stickers are pretty cool too - I've put one on my remote control (its super sticky so can't see that coming off anytime soon thankfully!) and I've added one to the underside of my bicycle saddle - its a £2k mountain bike so I really want to ensure I've got a chance to find it should it ever get stolen. Overall, I'm loving these new Tiles."

Another reviewer raved about the product's convenience: "This really is an excellent product. The whole tile range has brilliant and works very well. Absolutely delighted. The panic to find my keys in the morning has gone. One really useful feature is you can see on the map the last placeThat your phone had Bluetooth contacts with the item."
