They will report the location to you if someone with an iphone or ipad gets within about 40 feet of it.
You can see the location on your iphone/ipad using the Find My app.
The airtag battery is supposed to last for about a year and is easy to replace.
I've looked into the miTrail GPS devices - they are not very reliable - go offline for extended periods at random, and the battery powered one - the battery last for a week if the device is not moving. Put it on something moving and it reports it's location every minute and the battery lasts about 16 hours.
