Looks nice, but I hate that it uses a non-replaceable battery.
I've got quite a few Tile and Chipolo trackers, and they all use standard CR2032 or 1632, and they last about a year (?).
But I'll never have to worry about replacing the tracker because of the battery. My first Tile trackers are going strong 7 to 8 years at this point! LOL
