Have I bought this keyboard because I missed the button illumination at the SteelSeries Shift. But this is the G105 significantly "toy moderate", and also the key illumination bringt's not really, because the label is very small, at least compared to the SteelSeries. After all, the WASD and arrow keys are highlighted, but unfortunately with the same surface as any other, which brings not much while gambling in a darkened room, because, for example wants to sleep, the good lady. The keyboard slides easily around, and using the Fn keys for volume control is to vergesssen because the label is virtually invisible mounted sideways. The Implied palm rest is to forget. Thus, compared to the SteelSeries Shift not real, usable advantages, but some disadvantages. Therefore, I use now but again the SteelSeries Shift.
