Here is my review after 2 days of usage of this phone.
What I liked:
* Weight of phone including battery is quiet light.
* Look and feel is very much attractive, my colleagues compared with their expensive samsung phones, this phone also looks of same segment.
* Fine details on edge looks posh, it gets broader at the bottom, overall it is great.
* UI and 5.1 lollipop is simple and very organised.
* Music setting has a feature called Adapt sound, it enable every individual to fine tune the amount of sound for both ears, so that it suites you best without hurting your eardrums. The earphone which come is bad for music lovers, try getting your best brand's headphone, I use sony xb400 (old one,that time price was aprx 2K) it bounces nice. ;)
* Apart from this every feature is nicely blended to cooperate daily life activities.
* There is no heating issue yet.
* This phone is definitely value for money product.
What I didn't like:
* No notification lights.
* The speakers are not good.
* No themes
* Less default wallpapers
