The alarm is genuinely loud enough to hear from the next room, which is impressive for something thinner than a credit card. Setup in the Find My app took under two minutes and it’s been showing up accurately on my keys ever since.
I was worried a card this thin (2.4mm) wouldn't fit my tight cardholder, but it slid in easily and the Find My tracking works immediately on my iPhone. The alarm is genuinely loud for something so slim—I actually heard it from across the room when I pinged it to test.
Slipped it into my wallet and forgot it was there until I needed it—the 2.4mm thickness is honestly a non-issue. Setting it up in the Find My app took less than a minute, and it’s already pinged my phone twice when I left it behind at a café.
