    I have had it for a month and so far it is exactly what I wanted. Perfect for its price. I haven't charged its battery even when I received it. It came at 60% in November and by the end of March it has gone down to 20%. I'm waiting to see when it will discharge. I don't use it for gaming so I don't have an opinion, but I use the laptop quite a bit for my work.

    One downside is the accompanying application. Dell's peripheral manager works, but with every update it needs to be set up again from scratch, although it does the basic functions anyway. Overall, I am quite satisfied
