The AirTag is nothing short of portable insurance. If (when) you lose an essential item, the usual panic gives way to ease as you reach calmy for the "Find My" app on your Apple device of choice.
Wallets, keys, passports, suitcases—the AirTag has it covered. Couldn't imagine life without it.
You can buy them in singles, but you'll want four (or more) of them to cover all your essentials.
