eufy Security by Anker SmartTrack Link (Black, 2-Pack), Android not Supported, Works with Apple Find My (iOS only), Key Finder, Bluetooth Tracker for Earbuds and Luggage, Phone Finder, Water Resistant

Why it's worth it

The eufy SmartTrack Link taps the same Apple Find My network as an AirTag and adds free left-behind alerts, all at a small share of Apple's per-tag cost. You give up the precision arrow, but for tagging several bags at once that's an easy trade.

If you're covering four bags for a family trip, the math here is hard to argue with. Each SmartTrack Link costs a fraction of an AirTag and reaches the identical Find My network — the same billions of Apple devices, the same map, the same app you already have. For breadth of coverage per dollar, nothing else in this roundup is close.

The trade-off is precision, not coverage. There's no ultra-wideband chip, so the app navigates you to a pin on a map rather than an arrow pointing at your bag. Within Bluetooth range you ring it and follow the sound. In a quiet hallway that's fine; in a loud baggage hall it means more hunting.
