Last year we took a look at ROCCAT's ISKU Illuminated gaming keyboard and we really did like it, especially for the fact that was not a mechanical keyboard, but was still very comfortable and had many features that gamers would enjoy. While the original ISKU did have blue backlit keys many gamers wanted customization over the color of the backlighting. This is where the ISKU FX comes in, it adds customizable backlighting to the ISKU keyboard enabling you to change the color to any color you would like and it also adds in some cool lighting effects. Read on as we take a look.
