This isn't meant to necro this thread, but my order of 4 of these arrived today. They came in a black Ziplock bag with all the bits and bobs.
Initial impressions are pretty positive. They are built well, use torx screws to assemble the case, and fully assembled, it's about the size of a toy harmonica. 1 1/2" x 4 1/2" x 3/4". The case is all black, with "Elevation Labs" in small print on one of the corners. Nothing else on the case to identify what it actually is.
No issues putting one together - it just works.
Surprisingly, the chime of the AirTag is still quite audible even inside the case. There should be no trouble locating one of these by sound.
My use case for these is to put them in our vehicles and luggage. In the case of the car, I don't want to have to go dig it out of wherever I hid it. For the luggage, the battery always craps out just after taking them out of the house.
So this should do the trick for me. Now I need to wait and see what the battery life is like.
