Logitech 804360-1000/T-BB18 Trackman Wheel Optical Trackball Mouse, USB-A

The Logitech 804360-1000/T-BB18 Trackman Wheel Optical Trackball Mouse is a classic, wired, ergonomic trackball mouse designed for right-handed users. It features an optical tracking system (utilizing “optical Marble technology” as Logitech called it) for precise and smooth cursor movement, eliminating the need for frequent cleaning typical of older mechanical trackballs.

A key highlight is its thumb-controlled trackball, which allows users to move the cursor by rolling the ball with their thumb, significantly reducing wrist and arm movement compared to a traditional mouse. It also includes a scroll wheel and three customizable buttons for enhanced navigation and functionality.

Connecting via USB-A, the T-BB18 is known for its comfortable design, aiming to reduce hand fatigue during extended use. It was a popular choice for users seeking an alternative input device that offered precision and ergonomic benefits.
