Software technically there is also a great package. The software allows all profiles, colors of LEDs, macros, and other key assignments set. For me personally, the 12! Some thumb buttons too much, but good - who needs who needs them: D
They can at least easily operate with your thumb and if you set up properly they use a well probably :)
The LEDs can I find "LK20 keypad" very successful in mice, unlike those in the. Everything is Illuminated, beautiful brightness, Dimmable, liquid "Breathe" function and all possible colors important. TOP!
Small View Notes in the margin: My mouse has in the palmrest area no "LC" but a cool lion's head (which added to the Roccat logo resembles) which is illuminated by LEDs. I do not know whether the images here show at Amazon an old version or something, at least I find the lion's head already fancier than the "LC" from the reference image. :)
