I've used it many times...

I'm also sorry to say.

My phone has a car locator.... I forget how it works, but it does. When you park it marks the location... don't need one of those 'finder thingies' like an Air Tag. I just tried it using the app "Maps" on an iPhone... had to type in "parked car" and it found it. BUT... I remember I've done it a different way... just can't remember how.

I have an air tag wallet.... I've also got an air tag attached to my TV remote since the remote is always getting lost, usually in the sofa somewhere.

For those who don't know... an Air Tag is a finder thingie... there are other brands... "Tile" is one.... it works with an app on a smartphone - plays a sound or with and Air Tag gives you a map of the location and the direction you need to go and how far from you it is.... the other brands may do the same, I'm not sure.
