Im using this product from 3 years .and Im not finding such problem in this product.the build quality is very nice .
And the all the features provided by Lenovo in very low price as compare to other brand like Sony and Samsung.basically this product is very good for those who want all features in their laptop with less budget.so I would surely recommend to anyone whose budget is less .
Very nice product with affordable price.one disadvantage of this laptop is it is little heavy .if you are ok with weight then surely go for this product.sometimes processor get stuck in between when you are working on your project.as the operating system depend on you whether you want with your laptop or not .because it will come with both configuration.
Basically it is very good for those who are working in corporate field as well as student those are pursuing their degree .because they need every semester different kind of configuration in their laptop .same case happen with pro people they need different configuration with respect to every new project.so would surely recommend to you if you are ok with few issue .
