ELECOM EX-G Wireless Trackball Mouse, Left-Handed, 6 Buttons, Tilt Wheel (Left/Right Scroll), Black, M-XT4DRBK

This left-handed, thumb-operated wireless trackball offers solid basic performance and unprecedented new features. It features a gaming-grade, high-performance optical sensor to detect trackball movement, and a new, high-performance lens and optimized peripheral optical design deliver exceptional pointer tracking. The large 2.5mm artificial ruby ​​ball improves the feel of the trackball. The larger diameter of the ball also reduces the likelihood of it becoming embedded in grime and other debris, reducing maintenance frequency. The design takes into account the contours and bulges of the six bones and muscles of the hand that come into contact with the trackball during operation, achieving a new, comfortable feel that mirrors the shape of your palm. The trackball is equipped with "forward" and "back" buttons to improve web browsing efficiency. The size and shape of the buttons have been carefully designed to make them easier to access.
