Review on Smart bracelet Xiaomi Mi Band 2, black by Boyan Nedkov Tsonev ᠌

Output: The main feature of the bracelet is a pulse meter. The pulse under load is measured very inaccurately. There is no point in this bracelet. I checked the accuracy of measurements with three copies, they all have one problem. Different pros: Simplicity, reliability and autonomy are the main advantages of this device. Has some cons: There are actually a lot of shortcomings and most of them to the application. - The biggest downside. Why is there no stopwatch function? This is a fitness bracelet, what kind of fitness can be without a stopwatch? - Why can't you temporarily turn off the pedometer? On the way from home to work and back, sitting in the car, I wind up 4,000 steps - Why does the accuracy of heart rate tend to zero when leaving a state of rest? At rest, it measures normally, but why should I know my pulse is normal? I want to know the moment of excess in order to take the pills. But a pulse above 90-100 is normal to measure one time out of five - The screen is small
