Since the release of our first mouse, we have been using Japanese-inspiration in our naming of them. Our mice are built for performance and tournament-style play; Ikari means anger, Xai means talent, and the list of product names goes on. The Sensei is our version of the grand-master in our Do Jo. It is the teacher. The Sensei [RAW] is that master in his pure and focused form. With tournament grade components and focused intent, the Sensei [RAW] is the essence of performance delivering only what you need to eliminate your challengers.SteelSeries Sensei [RAW] did away with processor, the LCD menu system and the on-board memory. If you don’t travel around the world as a pro gamer, if you don’t plug into tournament computers and if you don’t need all the colors, the [RAW] will deliver the same world-class performance and same amazing customization options using the SteelSeries Engine. And Sensei [RAW] is available in 2 versions: one with rubberized soft-touch surface, one with smooth glossy surface–pick your favorite feel and start fragging.
