This is the most dramatic gaming mouse trailer of 2013. It is for a mouse that leaps across canyons in a sports car in slow motion. The new Razer Naga does not do that, but it's wonderfully clicky.
Last year I pitted three MMO gaming mice against each other in a battle of the buttons, and Razer's 12-button Naga did not win. It was a lovely piece of hardware, but the 12 side buttosn were smooth and hard to tell apart, and despite a set of swappabel ergnomic bits, the Naga just wasn't as comfortable as the competition.
