With Apple’s second-gen AirTags now widely available, we’re already seeing inventory of the first-gen model begin to dwindle. Amazon is no longer selling a single AirTag, and it’s unclear when — or if — the retailer will restock the first-gen model. If you’re an iPhone owner, you’d be hard-pressed to find another tracker that’s as precise or as helpful as Apple’s AirTag. That’s because, like the second-gen model, the original can tap into Apple’s vast Find My network and leverage ultra wideband (UWB) technology. In addition to the aforementioned software perks, Apple’s handy location trackers are designed to last.
