I can say it's paisa wasul laptop.
I am using this laptop from past 1.5 yr. And personally I evaluated the laptop as-
It's ideal for students and official purpose but not recommend for gamers and hardcore GUI programmer or designer.
Storage- I think 1 TB is more than enough for me still 400GB space available although I am moviefreek man.
RAM- multiple application runs smoothly at inbuilt 4GB RAM which can be integrated upto 16GB ( 8+ 8)
Battery- Its average.
Some humming sound comes from motherboard which can be listen clearly at night's silence.
It is made of fully polycarbonate-pvc body with decent look but not metallic finish.
If you go it's service centre than please go with its billing invoice because service centre don't v have all product warranty updated list they will ask you. In my case they asked to bring hardcopy of my laptop's invoice copy.
I think it will be helpful for you all.
Thanks
