4Pcs Smart Tag GPS Tracker, BLE 5.2 Wireless Anti-Lost Locator, Works with iOS & Android, Wallet Key Finder for Samsung Xiaomi

During extended use, the tags perform reliably — buyers report that the battery lasts at least several weeks without significant degradation. Locating works in two modes: within Bluetooth range, the tag beeps on command; beyond range, it relies on the network of Android phones nearby, meaning accuracy depends on the density of other Android devices in the area. Some users noticed the tag beeping on its own after 1–2 hours without apparent reason. The alert sound is described as low to moderate, which some view as a drawback.

The main issue is compatibility — several buyers reported difficulty pairing the tags with their Android devices, especially with older versions or certain phone brands. One buyer noted that the listing promises Android 9 but the app requires Android 15. Another problem is that these tags use an older version of Locatag software without distance alert support, meaning they don't utilize the full potential of the Find My Device network. Approximately 7 percent of reviews are critical, with some buyers calling them non-functional or a "scam" due to reliance on Bluetooth and network availability.
