Review on Smart Xiaomi Mi Smart Band Bracelet 4 NFC RU, black by Chai Charoen ᠌

Revainrating 4 out of 5

I like it, thanks for the quality product.

Well suited for an ordinary person to monitor activity. For sports, you probably need more serious gadgets. Sleep monitoring is not entirely accurate, it increases the value of sleep upwards. You woke up, turned around, even got up, but for the bracelet you are still sleeping. Also, if you woke up closer to the morning and were awake (conditionally) for about an hour, and then fell asleep again, the bracelet will not count the second period of sleep. May be important for people with floating sleep patterns.

Pros
  • Excellent autonomy. Initially, I thought what difference does it make to charge the bracelet once a week or once a month, but no, this is a real plus. Good monitoring of physical activity. The heart rate monitor is quite accurate. Actually, everything you need from this device is with it.
Cons
  • Does not track sleep during the day or at night after a long break. There are questions about this function as a whole (see comment).
