If you take this device for heart rate training, then this "sports watch" will drive you into a coffin. The pulse correctly shows only at rest. The more intense the training, the greater the error. Training was carried out simultaneously with a heart rate monitor with a chest sensor. As a result, the average value for the chest for a workout is 140, for this watch 120. During the training itself, the chest showed 145, the same watch 110. In general, this is an overpriced toy. If there was a correct display of the pulse, it would be possible to put 10 stars. And immediately the answer for Huawei representatives is that the watch is dressed correctly, according to the instructions, the sensor is clean, the hand is dry.
