The brand which is going on from many years and I prefer each and everybody to use this brand if you are buying any laptop and Its from my own experience because I already have 2laptops of lenovo and its really amazing with first class features and very super class performance. It is useful for official, students, businessman, etc etc. Nothing to say about this product be ause jt has got plenty of fearures and this product is really surprisingly, awesomenessly, too good enough, product can even think any other brand if u have this kind of brand with you
