I had used this laptop for over 6 months, and it is still working well . the i3 processor works pretty good and there is a no lagging at all even after running heavy games and softwares . it gets little more heat up than my lenovo g50
but it has a stronger body then it and speakers is very good despite of any other laptop in this category or range . there is no dolby digital but the sound is still fantastic without it . the webcam works good in sunlight but do not perform good in roomlight, this laptop comes with 4GB of ram but you can add extra ram in it and hard disk has a lot of space . in my opinion it is a good and strong laptop with great sound(PROCESSORS ARE ALL SAME IN EVERY LAPTOP BUT ONLY THEIR ASSEMBLING DIFFERS BRAND TO BRAND)
if u want a faster laptop for gaming purpose then go for lenovo g50
