When it comes to mice, SteelSeries over the past few years has basically stuck with a single design that they have used on multiple mice. We first saw it with the Xai and later the Sensei but they have also used it on various branded mice and a smaller version on the Kinzu as well. When SteelSeries announced that they were bringing out a new mouse design with the Rival I was very interested, but also a little worried about messing with a good thing. After a short wait, we finally have the Rival in hand and can put it through its paces and see how the new design performs.
