Review on Smart watch Amazfit Bip, black by Mateusz Gniazdowski ᠌

For a very long time I was looking for a watch with an accurate (at least with an error of 5%) heart rate monitor and I found it in them. By coincidence, I took this watch. Initially aimed at Sony swr, but it was nowhere to be sold. And I was faced with a choice: either a pig in a poke, or an already proven option (I borrowed them somehow from a friend). During the interval run, the pulse showed no higher than 125 all the time, at first I was upset, but if you catch the position of the bracelet on your arm and tighten it tightly (!), It shows quite accurately. Tested together with Beurer (who measure only when the button is pressed and is quite accurate, but inconvenient), deviations from 3 to 6 beats, both in the smaller and in the larger. The connection often disappears, but Huawei is most likely the culprit. Looking for GPS for a long time. To record a track in Strava, you need to synchronize with Zepp. Sleep monitoring seems to be normal, not so important for me.
