Review on Smart bracelet Xiaomi Mi Band 2, black by Virot Moonla ᠌

I'm not talking about the fact that the way the phases were fixed for me and those close to me shows that our family physiology differs from what is known about human sleep in general for homo sapiens. 2. During the day, if you sleep, then he does not notice this. 3. You go to the toilet at night, so he fixes it about every 5th time, but this is a few minutes. 4. Several times I recorded the pulse rate under 200 beats, despite the fact that at that moment I was sitting on a chair.
