Well got no words to say on this
Its really amazing for the people who are very much concerned about thes fitness.
I personally used and recommended my friends to buy Xiaomi’s mi band 2.
It really track your all activities like walking, running, calories burnt including heart rate.
Really comfortable after wearing.
Material used is a polymer material which is really smooth and pinned free.
Resistivity is awesome to sweat, water or any other liquors and also shows or intimates when call, messages or any notification recieved.
Battery life is a bit less when compared to its predecessor mi band 1.
A huge upgrade to Mi band is Mi band 2.
