Review on Smart Xiaomi Mi Smart Band Bracelet 4 NFC RU, black by Dimitar Miladinov ᠌

Satisfies basic needs. If you just measure steps and watch the time, then it will do. I do not recommend buying, it is better to save up or borrow a bracelet of a higher price segment. Pros: All basic functions are there, good autonomy and moisture protection Some cons: The heart rate monitor does not always work, with a high heart rate (more than 110) there is almost always a measurement error. It does not always accurately determine whether you are sleeping or not. At night, if, for example, you sit at the computer for several hours, you may think that you are sleeping. In the daytime, on the contrary, sleep - it means you just don’t move :) Perhaps this is subjective, but after a week of constant wearing, a rash appeared on the arm.
