I used the same model of this laptop 15 ac 122 tu I purchase this laptop when I was in 10th standard it was my 1st laptop . it cost me almost 33k including 2 year extended warranty. it life span is too good even now after 4 year of purchase still its performance is too good battery back is also more than average and I never invest a single penny on this laptop and still its was in good condition and I think it runs 3 year more from now it is stylish and yeah I want to clear with u guys its is not a gaming laptop it is good for programming, coding and daily basic use, this product is scored 9 out of 10 of my rating . I deduct 1 point for there cd drive it is not working but now a days cd drive is not an essential part so I m good with this problem
