It features eight buttons in total: left and right buttons, forward and back buttons, a tilt wheel, and three function-assignable buttons. The trackball's movement detection sensor is a gaming-grade, high-performance optical sensor, and the new high-performance lens and optimized peripheral optical design provide exceptional pointer tracking. The use of large 2.5mm diameter artificial ruby support balls improves the feel of controlling the ball. Furthermore, the larger diameter of the support balls makes them less susceptible to becoming clogged with dirt and grime, reducing the frequency of maintenance. By focusing on the six bones and muscles of the hand that come into contact during operation, and by designing it to take into account the indentations and protrusions, we have achieved a new, easy-to-use "feel" as if the shape of the palm were directly reflected in the design.
