It doesn't happen too often when a new optical gaming mouse receives hype. In-fact this past year up until now, all the mice we reviewed all used lasers and laser sensors. SteelSeries sent us their Rival gaming mouse which does feature an optical sensor as well as a number of other gaming-focused features.

It's often argued that optical sensors don't skip and thus track more reliably than laser sensors. In any case, better mice technology has narrowed the gap. We really haven't noticed mouse skipping on the laser mice we have reviewed and the Rival's optical sensor has a specified sensitivity, up to 6500 DPI, comparable to some laser mice out there. We'll have to see if the Rival stands out from the crowd or conforms to the rest.
