Phones: if not for Find My, oh god yes.

Keys: All the time. Now I have a tile on them.

Pens: lol yes, it’s why I’ve never tried to get into very-nice pens.

I’d have lost my AirPods several times without find my. I’m certain I’d not have managed to keep both buds more than a couple months if I weren’t very diligent about putting them back in the case when I’m not actively using them.

It's way easier for me to lose something the size and weight of a nickel than a phone. Not to mention ear buds do on occasion come lose and fall. With wired headphones, they dangle, but wireless buds fall into all manner of nooks, drains, and bottomless caverns.

If my phone hung off my ears and weighed so little that I could miss it, then I would be very nervous about it.
