I have used this phone for 6 months now and I must say that the phone is just awesome.The phone is mainly built out of plastic and there is a metal rim running around the edges.It is a very well built phone.The phone has a IR blaster which will be very useful for some users.Though the back is removable, the battery is sealed inside.The phone has a 5.0 inch display with 1080p resolution.The display sharp and crisp.The phone has powerful specs such as snapdragon 801 with andreno 330gpu and 3gb of RAM.It has 16gb/64gb of internal storage depending on your choice of model with no micro sd card support.The phone has no problems running intensive tasks.The phone is running miui on top of android kitkat with future lollipop update.Miui is highly customizable and user friendly.The only con it has is the lack of 4g and NFC which may be deal breaker for some users.
Overall its a beast from xiaomi in this price range.At 15000 rs it is definitely value for money.
