Review on Smart bracelet Xiaomi Mi Band 2, black by Ada Szymaniuk ᠌

So, I beg you to read my review, all those who buy a bracelet for sports! Attention for sports! The rest, as you wish. I have been running and boxing for over 15 years, it is very important for me to know when my heart is working at its limit. So the bracelet doesn't care! The heartbeat is measured simply randomly. How did you check? It’s very simple, on the treadmill I set the slope to 20%, slowed down the step, but the load was greater, seeing this Chinese bracelet began to show that my pulse began to drop to 125 beats ! Down Karl! Fortunately, the coach's chest gauge showed 180 as it should be. Pedometer, this is a separate story I will not tell. In short, who buys a bracelet for sports, do not even think to believe him, the maximum time to look. The manufacturers of this equipment should be held accountable for making false measurements, which will easily overload the heart muscle in inexperienced people.
