They're also extremely easy to set up and pair to your phone, thanks to the close pairing of Apple's hardware and iOS software. Just tap the AirTag to your phone to connect it to your account, and you're ready to go. They're compact enough that they can squeeze into basically anywhere, including on a keychain or tucked into a small purse. You can also share them with up to five family members, in case you need to help your significant other track down their keys.
