I will leave an additional feedback when I buy the buttery and connect the device. Bought it so I could find my car in the morning because I often forget where I parked it.

They arrived x fin but it was customs problem x the backlog s.

They work well order something slow 26/10/19 but arrived thanks

Thanks seller for keychain GPS tracker for dog. At first, when I received it, it did not work, did not produce any sounds and did not blink with light, then I stopped again the battery CR2032 and it earned. To it offers the seller download kindelf program, and in You Tube bloggers offer to download the program itracing, it also works, see who likes what program in work, they both work. When receiving the key-tracker, the batteries are not in it. Waited for a keychain for two months. Powered by Bluetooth.

Ok!
