I purchased this Mi Band HRX edition few days after its launch at Rs 1300 and till now it is working very good. It is an excellent battey backup foe more than a week.It is same as Mi band 2 but in this you will not get heart rate sensor for which it is cheaper too. It is an OLED screen which displays a good digits in it. It shows full accurate amount of calories I burn, the amount of steps I walk, even it shows all notification of your phone if it is connected to your phone. Behind leaving all these features it is an amazing fitness band at decent rate.
