Dell XPS 15 L502X is one of the good laptop available in the market. It’s cost is little bit expensive when compared to other brands as Dell is one of the best brand available in India. It’s design is good and it has good user interface to use and easy to use with no irritation in use. When comes to quality and durability it’s ok good, in some cases laptop may misbehave due to default in manufacturing time only(hardware problem). As all you know Dell provides good services all over the India and it has many service centers in India so it helps to troubleshoot the laptop when problem occurs, my overall review about dell XPS 15 is good.
