Review on Smart bracelet Amazfit Band 5, black by Stanislaw Szczesny ᠌

I chose between Amazfit Band 5 and Mi Band 5, I chose because of the oxygen sensor. In my opinion, it can be used as a toy - I observed the result from 86 to 96% within an hour. I measured according to the instructions. There is a comment in the Zepp app that measuring oxygen at the wrist is difficult and not very reliable, even the hair on the arm can affect. And then what to do with these measurements? Maybe real athletes know. About the steps - from the house to the subway about 2 km. I got it - on the bracelet 1790 steps, including morning throwing around the apartment. I decided to check - I counted 400 steps - the bracelet showed +300. Another time I counted up to 600 - +550 on the bracelet. Before that, there was an old man Mi Band 2 - maybe he also thought it was wrong, but there was no such obvious lie.
