Apple’s AirTags are a little bigger than a coin cell battery — surprisingly, they run on coin cell batteries — but despite their size, they offer impeccable tracking abilities. Powered by the Apple Find My network, the AirTags can ping nearby devices via Bluetooth to share their most recent location. And since there are so many iPhone, iPad and Mac users around the country and globe, there’s a good chance your AirTag will turn up even if you’ve lost it in some far-flung place. And if your AirTag turns up, so should whatever item you attached it to.

While the Find My network will get you close, the AirTags have a special trick to get you even closer. Using the ultra-wideband radios inside the iPhone 12 and newer models, your phone can point you in the direction of the missing AirTag and indicate how far away it is. When you’re right on top of it, you can have it play a sound. And just like that, you’ll have found your missing luggage, wallet, purse, bicycle — you name it.

With so much to keep track of, maybe that four-pack isn’t such a bad idea. That said, if you’re truly set on just buying one, the single AirTag is also seeing a slight discount at Amazon right now.
