I didnt like this laptop for many reasons some beign that it still comes with windows 8.1, asus must know that this is 2016 and windows 10 is a must and the ram( 2GB) its just not enough for a daily use latop where you have to load up huge softwares on a daily basics and the battery back is said to be 4 and a half hours but the actual back up I heard from the users is that, it lasts for about 2-3 hours and using this laptop while charging heats the base of the laptop I reccomend using an external cooler to be on the safe side.
