Best product under 2k range as compare to others. I have used the mi band 3 for almost 1 year and can cofidently say that it is the value for money. There is so much functionality built into it.
Pros-
Good battery life
Awesome water resistant
Light weight and good looking
Getting notification from call and message
Sleep analysis is best as per my observation
Cons-
Not visiable under direct sun light
It is too hard to remove tablet for charging from bend
Over all it is a good product, it’s battery absolutely awesome I got 18-20 days backup in a single charge. Hope this will be helpful while purchasing this band
