First of all build quality is very good. Band is also smooth. My skin is very sensitive, when I wear watches and other bands there is a redness and itching on my skin but after wearing this band my life is much easier and better and the plus point of this band it has a oled display which shows time, heart rate, steps, distance and also battery left. Unlike it’s predecessor mi band it’s pedometer is very accurate so always get accurate steps. Battery life is very good. But the user interface of mi band 2 app tyat is mi fit is not very good. Overall experience ??????
