Mi Bands will track your steps, track your sleeping patterns, work as a smart alarm clock (vibrate to wake you) and can last up to 30 days on a single charge, putting the Fitbit to shame by a huge margin.
In addition, if you have a Xiaomi phone, the band can unlock it wirelessly if close enough.
Xiaomi currently has a value of over $10 billion, especially notable for a three-year old company.
