I am using this laptop since last one year and not found any complaints as far as hardware parts are concerned it is so brilliantly designed by lenovo brand owned by IBM.
No doubt it is one of the best ever machine in case of personel computing robust body battery life is also long lasting keypad button is very very attractive that suits to my finger I used also before so many laptops from other brands like dell, HP, Acer and so on.
But I am going to vote for it because I have used it at my own service and support on software and hardware they take quick action their executives are so friendly I really liked
