Отзыв о Smart Xiaomi Mi Smart Band bracelet 6RU, black от Bali Bali ᠌

I am a teacher, during the lesson I am always on my feet, I walk a lot. I bought a bracelet to track activity during the lesson, because it’s not convenient to walk with a phone in my pocket to count steps. BUT something went wrong. For an hour and a half of the lesson, the bracelet counted only 200 steps. How is that in general? For an hour and a half of walking on the street, I get 10,000 steps. And with the continuous tracking of stress level turned on, there were no measurements at all during these one and a half hours. I'm thinking about whether to return it. I wonder if everyone in the room thinks badly, or is it a marriage of my bracelet.
