Xiaomi band 2 is a very good fitness tracking band for ?1999 I bought this band from China and used for 1month I got a battery life of 17days and it counts every step of mine and shows time, date and day and to use it we need to install mi fit app from play store/app store through this app we can set things to be done by band and it tracks heart rate and sleep timings. In sleep assistant It says how much time we were in deep sleep and light sleep and shows slept time and woke up time and calling& message notifications are felt by vibration of band and you can set 5 app notifications so that it notifies us. This was disappointing because they may give atleast 10apps
