The function is no different from the description.
The battery life is too short. I can use the GPS for about 3 days after exercising.

Just a good watch for the price.
The screen is fairly good. A little bright colours.
Gps is good.
Flash light is mediocre.
It counts heart rate every 5 minutes but you can see it only in the app.
If you want to see the heart rate on the watch you have to manually press to count your heart rate so you will have on your watch the same manual heart rate for days!
Good battery. About 3-4 days.
Sleep analyzation is good.
The app is the main disadvantage though.
I don't remember about a 24 hour spo2. Currently i switched back to huawei band 10 and oneplus watch 2r. Thanks for reading.
I am very satisfied with this watch, thank you shop very much
Beautiful watch, thank you!
Very beautiful watch. 😁
