Great watch but after month of use It was destroyed by airport security and now I switched to my old mi band 4... Battery lasts like is in instruction with all fuctions on 4 days, without 24hour monitoring lasts 13 days with 2 active days using gps, similar to my mi band 4, gps works correctly but compare to my bryton rider 15 some segments on strava were driven by in shorter time, some in longer time but there seconds, the only one thing wasn't correct was speed it was showing maximum speed of 82km which is wrong... either way watch can be used to measure gps and heart rate on trainings but for now I'm staying with my bryton on and speed sensor on the wheel.
Smart watch is ok. For me it missing some simple features like setting alarms directly from the smartwatch. Has lots of sport trennings. In comparison with Mi Band it's properly counting steps, heart rate and kilometers. both shows same values. I can only complains for smartwatch faces. Most of them looks not professional. weather is missing. application for phone could be better. smartwatch has poor Bluetooth - 4m from phone and it lost signal.
