【Description】 ■ This is a left-handed, thumb-operated wireless trackball equipped with reliable basic performance and unprecedented new features. ■ The trackball's movement detection sensor is a gaming-grade high-performance optical sensor, and the new high-performance lens and optimized surrounding optical design achieve exceptional pointer tracking.

■ By using large 2.5mm diameter artificial ruby ​​support balls, the feel of controlling the mouse is improved. Furthermore, the larger diameter of the support balls makes them less likely to become clogged with dirt and grime, reducing the frequency of maintenance.

■ Focusing on the six bones and muscles of the hand that come into contact during operation, the design takes into account indentations and protrusions, achieving a new, easy-to-use "feel" as if the shape of the palm were directly reflected.

■ Equipped with "forward" and "back" buttons to improve the efficiency of web page browsing. The size and shape of the buttons have been improved for easier access.

■ One customizable function button is located where the ring finger rests.

■ The left and right buttons use OMRON switches, known for their high reliability in terms of durability and their renowned click feel.

■ Equipped with a tilt wheel that allows you to scroll left and right simply by tilting the wheel. Convenient for operating wide screens such as those in Excel.

■ A speed change switch allows you to switch between two pointer movement speeds: 1500/750 counts. ■ Button functions can be changed using the free downloadable "ELECOM Mouse Assistant" software.

■ The ball can be easily removed through a hole on the underside, making maintenance of the ball and internal ball holder easy.

■ It uses a 2.4GHz wireless band and can be used within a range of approximately 10m on non-magnetic surfaces and approximately 3m on magnetic surfaces such as steel desks. (According to our research)

■ It uses a micro-receiver the size of a 1-yen coin that is unobtrusive when connected to a laptop's USB port and can be carried around while attached.

■ The receiver can be stored inside the mouse body, making it convenient to carry and reducing the worry of losing the receiver.

■ There is a power switch on the underside of the unit to prevent battery drain when not in use.

■ It is equipped with a battery level indicator light to notify you when it is time to replace the battery.

■ This is a simplified package model that is easy to unpack.
