I purchased this mi band 3 from official website of mi and it delivered with in 4 days. It was well packed and delivered safely. The band is come with basic manual and charger. The band is superb in design and very light to wear the best part I love is it displays the msz on the screen. The best part is the alarm it continues ring until you wokeup. Superb design and unmatchable build quality screen is super clear even in sunlight it is clear visisble. Battery life is also very good it runs upto 3-4 days. Acurate measure all the parameters like herat rate etc. The app it supports is also very attractive. Very easy to use.
