If you are looking for a basic activity and sleep tracker, then the Xiaomi Mi Band does the job very well. We wouldn't recommend it for those who can get by with a smartphone's built-in sensors, as any of the numerous available fitness tracking apps provide the same functionality. However, if you don't carry your phone with you all the time, then the Mi Band is a useful, affordable gadget that you'd probably want to buy. Xiaomi's pricing is excellent as usual - at Rs. 999, it's an inexpensive purchase even if you just want to see what the wearables fuss is all about.
