Summary: I am really enjoying this keyboard, even though I inadvertently purchased the British Keyboard layout instead of US (whoops!). Good quality, excellent backlight and excellent, strong feel to the keys. I highly recommend this to other gamers.
Summary: I got the mouse as well 79158 for Roccat talk effect. Not worth buying for the effect as they seams to be glowing off sink most of the time. Have to download the drivers from website. Macro cap locks, num lock button are always blue and can not follow other key color change. You can not custom change any single key or region of the keyboard. You can assign macro to the ASD region.
Pros: macro, quick key, and functions key on top of keyboard.
Cons: Color breath switch dry, not as smooth as expected. ROCCAT talk out of sink with mouse.
Summary: The keyboard is nice looking and very customizable. Unfortunately, what I received had a half sized left shift key. After all the years of adapting to and using a full sized key, I could not make myself comfortable enough to keep this. So I am sending it back. Wireless would also be a nice addition.
