Attach a $29 Apple AirTag to your stuff and you can use your iPhone to locate it when it goes missing. WSJ’s Joanna Stern put the new gadget up against a drug-detection dog and other lost-item trackers, like the Tile Pro, in a series of indoor and outdoor challenges.
Take a look at the video below. You can purchase one AirTag for $29 or get four for $99. The Whistle Go Explore is available for $129.95.
