    Works Fine
    So far, the watch works fine. Everything seems like alright. The screen display effect is good under the strong light, but I can see the screen contents very clearly.

    What impressed me most is the heart rate monitoring function, which is very accurate and precise. I got to know my heart rate data in different states at any time, which is very useful and worth referring to for me.

    And it charges very quickly, filling up in less than two hours.

    Silicone watchband wearing very comfortable breathable, after the exercise, it is not stuffy. It's a very beautiful design. I like it very much.
