Review: Onn Item Locator vs. AirTag
The Onn Item Locator, available exclusively from Walmart for $15, is a cheaper alternative to Apple's AirTag, but it only works with iPhones and has a fundamental advantage over AirTag as it has a hole built into the case, so you can easily slip it onto a keyring. However, the author tried two of them, and both turned out to be defective, with the battery level below half within two weeks and the tracker not functioning consistently. The author cannot recommend the Onn Item Tracker and suggests picking a different tracker.
