Being a close to year old model, there are good number of detailed reviews on the internet. I think this handset is pretty good for the price I paid during the offer @ 13.5.
Pros:
1) Gorgeous display, strong build quality, ergonomically designed for 5 incher. Xiaomi phones are known for being looker.
2) Pretty quick, crisp and clear daylight camera, both front and back. Though low light is going to be grainy for most smartphones
3) 3GB Ram under performance mode is a delight and so is the MIUI. Its pretty beautifully designed.
4) Snapdragon 801 is Qualcomms most successful and stable SoC. Its really fast. Dont go by cores. A devices performance is based on multiple parameters. Cons:
1) MIUI is this devices strength and weakness. Its pretty heavy and takes toll. So, unless ure using it under performance mode, itll start feeling sluggish after a while though ull never run out of memory. The skin really just too heavy.
2) Very slight warming observed on display as well as back after extended internet usage, though its really mAnasultangeable
