First of all i want to mention is the quality, the keys are very smooth to the touch and the gloss black surface around the keys makes the keyboard look very sleek. At first glance my friend's impression was WOW!
The touch sensitive section responds to the lightest of touches, great for switching songs or pausing DVDs while in game. Some people think the brightness of the keyboard could be better, but i think that would make them too bright and distracting when gaming.
The razer software is very user friendly and it's so easy to create your own macros gorillas could do it.
The only down sides to the keyboard are, the gloss black shows up fingerprints, only one height setting, when you disable the windows key there is no way to tell if its disabled other than to try it. (They should make the backlight go out on the key)
Hope you've found this helpful. Triston
