Review on Smart bracelet Xiaomi Mi Band 3 Global, black by Michael Baek ᠌

The pedometer overestimates the readings several times! You walk half a kilometer - draws in the region of 4,000 thousand steps. The heart rate monitor out of about 20 attempts to measure the pulse showed a result similar to the truth twice. A few more times showed random numbers (for example, 66 immediately after intense physical exercise). But basically it shows a cross (cannot count the pulse), no matter how you move it along the arm in search of the desired position. In general, none of the main functions of the fitness bracelet works. Of course, I will try to hand it in for repair or replace it, but I don’t particularly believe in success - formally, nothing is broken, what is it, calibrate it, or what?
