I took the watch primarily as a fitness device for tracking activity. Helped me lose 25kg. It is clear that this is not 100% accuracy, but the dynamics can always be tracked. They work an average of 3 days, which suits me. You can connect with heart rate sensors. Notifications come, finally turned off the sound on the phone)) Sometimes the pulse is read incorrectly, but in general it is ok. Recently, for some reason, they behave strangely with the gps of the phone, they do not always track correctly and do not map the map. But there is strava, so I don't suffer much. Push-button control is ideal for me, during training it would hardly be possible to adequately hit the touch)) In general, the watch approached me 100%
