Has anyone used a GPS tracker before?

Hey guys! :paw_prints: I just got a puppy and started considering GPS trackers for dog collars. :star2: Has anyone used the Tractive GPS Dog 4 or another brand? :watch: How do you find it? :dog: Did it come in handy during emergencies? :rotating_light: Do you think it’s necessary alongside tags and microchips? :bulb: Is charging it or paying for subscriptions inconvenient? :money_with_wings: Would you buy it again knowing what you know now? Sharing your experiences will be highly appreciated!
