After so many rumours, the first look of Xiaomi’s Band 2 has finally surfaced courtesy Xiaomi’s chief executive officer and founder Lei Jun. He put a teaser video of a band on Weibo which everyone expect to be that of Band 2.
As is seen in the video, the band has an LED display that shows time. There is a circular physical button as well. The core seems to be removable from the strap which seems to be made of rubber. 
Though not confirmed, the band is most likely to show steps taken, calorie count atleast. It might also come with a heart rate sensor.
Not much is known about the Xiaomi Band 2 as of now. But considering Xiaomi’s products, it should be very competitively priced and may be launched very soon.
