I purchased this phone last week and I am very happy with this device. It is my first Mi device and after using this mobile for a week I can say that I am not at all bored with this mobile phone.
the first and the best thing I liked most in this mobile is its battery backup which is 4100 mah which is very very large according to this price. and after using this phone for 8 hours of high usage its battery drain from 100 to 57 percent.
Now the thing that I dislike in this mobile is its camera which is not so bad but average but at this price and all these kind of awesome feature, I can forget this lack. Although in day light its clarity and auto focus is very nice.
I bought this mobile by trusting on mi for the first time and they know that how to make customer happy. So I can say that you can go for this mobile.
