The ROCCAT Kone XTD was a bit of a flash back to the previous ROCCAT Kone and Kone[+], with near identical looks and features. Its added weight kit and 4-LED lighting scheme allowed for a rather personalized setup. Unfortunately the software was the ultimate fail in both the XTD and Pure mice. The installer crashing while it installs and crashing while writing to the mouse are two major no-no's. That's the last thing I need to happen when I'm just trying to customize my mouse. I could deal without the flashy imagery as long as the mouse works and the settings I want to change actually send to the mouse. Despite my anger with the software, I ultimately enjoyed the XTD.
