I got 4 for tracking cases on our recent transatlantic flights with family, now home, looking for uses. Got a ridge wallet so probably gonna get the airtag attachment for it, will keep one with my keys and the other two will stay with mine and Mrs F's suitcases for trips away, possibly might get Mrs F's bag tagged also on her account so she can keep track of her handbag and possibly set one up on her work bag too.
