Review on Smart bracelet HUAWEI Band 4 Pro, graphite black by Somchai Vongxaiburan ᠌

There was a technological defect, standard for this bracelet - a blue "light" of the screen in sunlight or ultraviolet (batch 01/20). As a result, after 11 months of operation, under warranty, I replaced the bracelet with a new one without screen marriage (batch 09/20). I didn’t like the accuracy of measuring all indicators - when measurements were made in a row, the readings differ, the sensors find the pulse and oxygen level of inanimate objects (I did tests on apples, tangerines and sausage .))) That is, it’s not suitable for sports at all, only as a toy. I didn’t like the fact that it only works with the “native” application, which doesn’t normally transmit the collected data even in Google Fit (neither pulse nor oxygen). I didn’t like that for some reason the black bracelet comes with a white cable for charging and is very short. I didn’t like that after 11 months of use, the bracelet began to react quite sluggishly to the turn of the hand, and the strap began to slip out from under the limiter all the time. I didn’t like that the worn out strap of the bracelet, when worn for a long time, personally caused severe irritation on my skin.
