Let me divide the review in pros and cons.
Pros:
1) The phone is compact and looks good and build quality is good.
2) The snapdragon 410 is good for light gaming and everyday usage, ( dont expect high end gaming here)
3) The rear camera is very good with good clarity in pictures, the front cam is decent. Full Hd videos recording is supported and the quality is good.
4) The battery will last a day with moderate usage.
5) MiUi is lag free and beautifull.
6) 2GB ram and 16 gb internal storage.
Cons:
1) No updates to android version, so the phone is stuck on kitkat.
