Tile Sticker is the newest form factor of the Tile tracker.
You can get Tile Stickers in a pack of two for S$59 or in a pack of four for S$99 from AXTRO Sports.
It measures 27 mm in diameter and 7.3 mm in thickness, which makes it slightly larger than the size of a Singapore 50 cents coin. Also, that makes it the smallest Tile tracker so far.
Instead of the usual way of hanging your Tile Mate/Pro tracker using keyrings, the Tile Sticker comes with a 3M adhesive at the back for you to stick it on objects.
The 3M adhesive is sticky, and once it is stuck to an object, you will need a lot of force to remove it. And likely once removed, it will be damaged. So to re-stick it to another object, you might need to get another 3M adhesive.
Tile Sticker is waterproof, so you can even stick it to your GoPro Hero Camera or DJI Osmo Action Camera. Its range is around 150 feet (46 m).
The battery is non-replaceable, and it can last up to three years. In comparison, the non-replaceable battery on Tile Mate can only last for a year.
Because of its smaller form factor, Tile Sticker does not ring as loud as other Tile trackers. To me, the ringer volume of the Tile Sticker is still acceptable.
