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: Its a Very expensive and fancy gaming keyboard. Looks awesome, Feels awesome, price tag isn't awesome. A lot of hype around Roccat products. I did end up sending mine back as the software wouldn't install onto my computer for some unknown reason and the customer support told me to do everything that I had tried. In my honest opinion go for a cheaper gaming one (sidewinder X4) or if you label concious check out Razer products.
