Review on Pack of 4 Smart GPS Trackers: Key Finder Locator Wireless Anti Lost Alarm Sensor 📍 for Kids, Dogs, Car Keys, Wallets, Luggage - Compatible with iOS & Android, Controlled via App by Tabish Jadhav

1) Note that these are Bluetooth devices and therefore have a reliable range of 30-50ft, no more than 30-50ft on a GOOD day. 2) The application is a bit unusual and constantly notifies you when you walk or run. I turn it off and only use it when I'm looking for an object. 3) Speaking of the iSearching app, the iPhone version has an annoying habit of alerting every device when you exit the app. Manufacturers should offer an option NOT to do this.
