I personally have with the coloring of the WASD keys to write my problems and even now I find it more disturbing than helpful. Overall, the keyboard is well made but has a smaller screen than the G15, fewer tools and is also the feel is not quite as wertig as its predecessor, but since this is no longer produced, I had to resort to the G510s. Mechanical comes for me because of the volume while typing is not in question and the pricing fantasies of other manufacturers or the "upscale" product line of Logitech I'm not willing to inspire.
A solid product, but not a successful successor in the same price segment.
