Elecom revisited the grip comfort − the most important feature of a mouse. The beautiful form is designed to fit the skeleton and muscles of a hand. Instead of relying on abstract and vague concepts such as “ergonomic” and “easy to hold,” Elecom revisited the grip comfort in basic operations such as holding and moving a mouse. The smooth and streamlined form of this mouse naturally fits the proximal phalanx and adductor pollicis muscle of the thumb and the metacarpus and middle phalanx of the third finger, offering new grip comfort.
