It really is a great mouse. In addition to what the article said, i can add that the buttons and in particular the scrolling wheel have a really nice and precise feel to them.
However, the article left me wondering: did you not test the mouse on a mouse mat matching the price class of the mouse? I mean, sure, it's fun to read about it's performance on clay, but it might be a little more relevant to reveal how it performs on, say, a Razer Destructor.
I just so happen to own a Razer Destructor
, and i can report that, coupled with the Roccat Kone, the mouse slides with almost no resistance and is extremely precise.
