For the gamer side, I'm not sure if the lock switch the windows key, no macro, no dedicated key. This is not displease me, I do not use it.
Regarding the feature of this keyboard: the lighting.
4 and 5 modes customizations. And 5 brightness intensity.
Mode 1: Gaming Cluster (W, A, S, D, 4 directional keys)
Mode 2: Retro complete lighting
Mode 3: breathable light mode (max intensity rises and then falls etc)
Mode 4: ActivLite (Pressing causes the lighting of the key)
Mode 5: ActivLite (Pressing causes the lighting of the key that turns off
It's funny 5 minutes, and then never used. Maybe for those watching their keyboard typing, but playing ... it's useless.
Also in regard to lighting, the LED above the switch, so the lighting is uniform, but the bottom of the keys is very little light.
Another disadvantage, for example, when the windows key is blocked, the PRTSC glows permanent.
A firmware update is available on the website 1.20, when no description for corrections. Curious, I did it, it takes 3s and goes smoothly.
