Review on Smart bracelet Xiaomi Mi Band 3 Global, black by Seo Jun ᠌

I took it in the expectation that during charging I could constantly monitor the pulse, and exactly for this, the only function I need, the device is not suitable. I don’t know how the pedometer works, I didn’t check it - it doesn’t matter to me, and besides, there is a pedometer on the smartphone. With its pros. Lightweight, comfortable, does not interfere with the hand. It doesn't cause allergies in me, although I am a very sensitive allergic person. Got cons: As a heart rate monitor, the device is almost useless. In continuous mode, he lies shamelessly: at a pulse of 130 it shows 110 at 160 it shows 130. Late, or something, I don’t know. In single measurement mode, it shows exactly, but my smartphone measures faster and more reliably. Also, navigation for a single measurement is inconvenient - on the smartphone, he pressed his finger and that's it, and then you still need to unlock it, go through the menu with trembling fingers, which is also blocked if you move back incorrectly.
