I dropped one on a keychain on a sidewalk. It never pinged. That was an AirTag.

The other was the time I left my car keys on top of my car. Someone took the keys and put them in a random nearby business’s lost and found. The tile never pinged over the course of days and I had to find it the old fashioned way.

These things never worked for me, but it’s good to know that mail delivery people use these apps/devices that will let you track your packages in realtime.

I didn't realize I dropped AirPod Pros in a case with an AirTag. I watched them bounce around inside an unoccupied Google building like it was picked up by Google's security people. Then, I watched it commute to a residential area of a smaller town. The defunded local police wouldn't even possibly look into it until 48 hours later and only if they wanted to, and the smaller town police wouldn't do anything. It pinged for a day or two afterwards like someone had thrown it into a/their neighbor's trash can.

Lesson: Don't lose shit.
