After 5 years of smooth use of this product I am reviewing this .
I am using this lappy from 2012 till now no problem as well as battery issue which is general in all products but in my lappy till now no such type of issue minimum back up of mine lappy is around 2:30-3 hrs .
This is my first lappy and as a IT engineer I have to change this one and should get more performance lappy but this one is really unique no problem in working this one simply awesome lappy .
I can recommend this to everyone .
U can blindly trust this product.
