I use it as a clock and notifications. Sports functions of the watch are not interested. Oxygen measures, sometimes accurately, compared with a Little doctor medical pulse oximeter, but in the case of a watch, ideal conditions are needed. Light, this is very important for me. They connect with the Honor phone with BT 4.2 perfectly, keep the connection stable. The battery is excellent, I did not measure it, but they hold it for 2 weeks. Steps, dreams, pulses and workouts, I don’t use it, I can’t say anything. A lot of straps, cases, etc. are for sale, it's great. Charging is magnetic, very convenient. The screen is class, as it should be, the size is just ideal, and not big, not small, everything is fine, especially those who have poor eyesight. Vibro is strong, I liked it, better than on the old Mi Band 4. Notifications, with Vatsap, everything is perfectly readable with the text of the message, except for pictures and emoticons. But, it's annoying that the screen does not wake up when notifications from messengers arrive, only vibro, and you need to press the button to read it, tin. With calls, everything is fine, the screen wakes up as it should, but with a delay of 3 seconds, it's also somehow not very good. To be honest, I liked only the screen size and vibration, the rest is not very good.
