The keyboard is "smooth". Its lighting, which might seem to be a gimmick is absolutely not.
When the ambient light is not strong (working on photographs, for example), simply to approach the hand of the keyboard lights, which greatly facilitates the positioning of the hands and seizure. Perfect.
Furthermore, the autonomy of the keyboard and mouse is excellent, largely sufficient to hold more than one week in constant daily use.
I recommend this set without a second thought.
