I have been using this phone since a year. Its been working good since then. I would tell the pros and cons which I figured out after using.
Pros :
Superb sleek design with metallic cover.
Size is good. Easy to operate.
Quick fingerprint recognition.
Battery life is approx 14-16 hours with proper use.
Camera clicks good and fine pictures.
Cons:
Hybrid sim. You can’t have dual sims with 1 SD card.
Gets a bit warm while charging.
It is best phone for its price. I bought directly from MI site with 1 year warranty. It costs me 8999+ 600( 1 year warranty) .
