This keyboard has been nothing but nightmares. I am on my second RMA for LEDs turning pink. The first one, turned on to full white, would have pink LEDs after a while. Key caps were not the issue, as the physical LED would turn legit pink. I fought with ROCCAT for over a month to get another keyboard, after weeks of delay and twitter messages to get visibility. The new one also has keys turning pink - it has to be a manufacturing defect or choice in LEDs.
On top of that, their software that runs the RGB functions (as RBG effects do not work without the software) is hardcore trash. It doesn't like to auto start with Windows, and crashes the times it does. I scripted a workaround to start the program delayed after Windows starts. Their auto start fails and doesn't work. The UI for the software is not very intuitive either.
The key cap set they use on this is non standard, so forget trying to buy another set to further customize your work space. You are basically stuck with what you get until the LEDs die or you get fed up with the trash software and throw it away. I think there is one other company that makes key caps for these specifically, but why you got to make a vendor specific set? Doesn't that just increase the manufacturing cost and lowers customer experience?
I feel like I have a $110 piece of trash on my desk that I hate to leave on when I am not at my desk for the fear that the LEDs will die after months of use. I honestly can't wait for these LEDs to just die so I can take a hammer to it - the good ol' "Office Space" way.
