Otherwise, this is obviously a well thought out keyboard, solid, imposing size and pleasant to touch. The backlight is seen and is very useful to use, the responsiveness of the buttons is good. We appreciate the presence of two deported audio ports on the keyboard. The size of this keyboard will be an advantage for some, an inconvenience for others, a matter of taste! ... By cons, we can blame Logitech for not having visibly (or audibly) not made much effort on the noise of the keys. Still, this keyboard will undoubtedly meet the expectations of the average gamer, finally for a fairly tight price for the number of features offered. Recommend it so.
