Dell laptop its works very good I can use that laptop for previous five year.I had read reports that the early builds of the 9550 had issues, but that by now the systems were reliable. Clearly not true from my experience.all widow spot on that window x, window 7, window 8.1, and also window 10 which is latest version of windows.
value for money I say OK for this laptop according to the latest model and several functions included in the laptop.
Screen quality is highlight for the gaming and long time work. In these laptop the brightness will be automatically set by battery percentage.
