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.
