Function allocation of button is modifiable using "ELECOM mouse assistant" which we can download free.

In addition to right and left button (1, 2), button (3, 4) which "advances, and returns", it is equipped with tilt wheel (5), 8 buttons (6, 7, 8) of three function allocation buttons.

By adopting large artificial ruby of 2.5mm in diameter to support ball, a feeling of chastity ball improves. Again of support ball, by enlarging in diameter, support ball becomes hard to be buried among garbage such as dirt from the hands, and maintenance frequency decreases.

We put high-performance optics-type sensor of gaming grade on sensor detecting movement of track ball and realize distinguished pointer flattery characteristics by new high efficiency lens and optimization of neighboring optics designs.

It is realization for "expand feeling" that is new by design that paid its attention to six frames, muscles of the hand

In operation, paid the attention to frame, muscle of six to contact of the hand, and shape of palm seemed to be just projected at all by design that considered hollow and swelling, is easy to operate; is new; "expand, and realize feeling".
