Review on Smart bracelet Xiaomi Mi Band 2, black by Wiktor Niemiec ᠌

I’ve been using it for two years, at the beginning, I experimented a lot with this device, the pulse measures terribly . you make an approach in the gym, you stand, you can hardly breathe, it’s all wet in your eyes, it’s dark, but you get into the “pose” of measurement and it shows you an “error” , you gather your strength, you measure for the second time, and he shows you "56 pulse" what the is 56? I can barely stand on my feet . and from the fifth time he will show PROBABLY the correct one, when you have already calmed down. or in the subway you just stand like that, I decided to measure the pulse, clap "115" . yes, damn it, I'm just standing. so it's useless. what is convenient for me is a watch, and at night and during the day it is always "at hand") and the most convenient thing is that when there are calls, when walking I often do not feel the vibration of the phone, but on my hand I feel great that they are calling me!
