Review on Hangang Pet GPS Tracker: 2nd Generation Anti-Lost Dog Collar with Global GPS/GSM, Waterproof & Long Standby - Track with APP by Marcus Cano

Great product I live in a field in Argentina and I have 5 dogs, I can finally be calm when I can't see them. Even if you follow the instructions, it's not easy to get it working properly. In the beginning the GPS and SMS app sends me different and wrong locations and shows as inactive all the time. If you have any problem with the setup, please contact us by email at maize@cnhanguang.cn, she was very helpful and solved my problem in a short time. Now I can see my 5 dogs at the same time and the GPS is accurate enough.
