This Combo replaced a Logitech G110 as the Footprint is smaller
and the illumination works well.
The mouse sits well in a large hand, and the mouse wheel is
not hard to get too (not rebated in like others)
The keyboard has a nice click to the keystrokes, without being
as noisey and the old ( and NEW) mechanical Keyboards.
use "scroll lock" Key to Activate the illumination!!!
