Review on 📍 New! Tack GPS Location Tracker with FCC Certification, Extended 30-Day Battery Life, and Affordable Monthly Fee - Wonder Case for Pets, Children, Alzheimer's Patients, Dogs, Cats, Bikes, Cars, Vehicles, Motorcycles. GPS, WiFi, Cellular Connectivity. by Chris Cruz

I use this to track my dog. You can set safety zones and the app will notify you when the tracker leaves this zone. This happens quickly and the app is easy to use to see where the tracker is. It can be a bit out of the way at times, but it's still in the same area (and that's generally to be expected from any tracking device). Support was very quick to respond when I had an issue with the app not notifying me and they fixed the issue right away.
