I bought this phone abt 5 months back and its performance is terrific.I had a Samsung s3 previously and the difference is immediately noticeable. Great processor and 2 GB ram plus a good display and slim good looks plus the great miui software makes this a great buy.
Not to battery which comfortably lasts the entire day. Now there is mi4 which is even better. For this with smaller budgets the redmi note 4g is a great buy. All in all xiaomi phones are great. You can buy with your eyes closed.
