The Sensei Raw is one of the best form fitting laser mouse that SteelSeries has ever released. With a shape and shell that essentially fit any size hand as well as grip type, the mouse can be used rather universally. The buttons and materials have a nice grip feel to them that adds a lot of additional dexterity. Laser sensors are quite different to Optical ones and it's a relief to say that this Laser sensor has no major issues, although slight deceleration has been mentioned by some users. The sensor doesn’t spin out even when moved at fast speeds, it tracks extremely well, and has a good lift off distance. SteelSeries drivers will allow you to change the DPI, polling rate, bindable keys and much more.
