Review on Smart bracelet Xiaomi Mi Band 2, black by Avut Bouchen ᠌

Took to measure heart rate and sleep characteristics. But in a calm state, + - 5-10 hits come out, and while running, for example, in general, numbers from the ceiling, then 150, then immediately 48 hits. Those. you can measure the pulse only in a calm state, and this can be measured without this piece of iron. Steps are also measured so-so. In a dream, it seems, he does not count, but he can count something while sitting, for example. Yes, and while walking, too, it can lie more than it really is. In general, paradoxically, but I recommend taking this particular thing. The technology that is used in the bracelets does not allow you to accurately measure the pulse during activity and more accurately than this piece of iron, no other, even for several tens of thousands of, will measure, the technology is the same. The error is large, but it is quite possible to use if for yourself.
