The reason why the KeepB3 sports bracelet likes it best is that it can change the dial. There are not only 100+ different styles of dial wallpaper, but also you can change it every day according to your mood or your clothing.

The menu part of the bracelet has options of exercise, breathing, heart rate, blood oxygen and timing, as well as independent exercise modes built in the bracelet, including running, walking, swimming, spinning, yoga, ball games, rowing machine, elliptical machine and free training.
