Отзыв о Smart bracelet HONOR Band 5, blue от Yusri Awin ᠌

I do not recommend taking it to those who purchase for training. Pros below: Analyzes sleep phases. The readings appear to be reliable. It is possible to measure oxygen saturation, it is very important in our time, I can not confirm the accuracy of the measurement. Smart alarm seems to work. Some cons: During intensive training, the pulse is not measured correctly: the real pulse was 150, the watch showed a value of 90. I tried to place it on my hands in different ways, tighten the strap with different strengths - all the same, the watch is lying. As soon as the real pulse goes beyond the border of about 130, it starts to lie.
