As I use this keyboard more and more I want my G15 logitech back. I'll start with the driver, as if you use the driver expect access violations. The keyboard itself is nice it looks good feels good. The buttons respond well most of the time. I have noticed some times that when I hold a key it won't repeat it just acts like I just hit the key. Other things are that it won't go beyond about 8 key presses a second. So if there are any K-stylers looking for a good fast keyboard to help you out a little, don't pick this keyboard. you will find yourself tumbling when you hss or hs. Getting past all of that, the keys are relatively nice and easy to push. The coating on the keys wears off very fast, or it could be that I just use it to much. ;)
