What is logitech trackballs?

Logitech trackballs are input devices that allow users to move the cursor on a computer screen by rolling a ball with their fingers or palm. Unlike mice, which require space to move around, trackballs can be used in confined spaces and are popular among professionals who need precision and comfort. Logitech offers a range of trackballs, including the Trackman Marble and the MX Ergo, which are designed to reduce wrist strain and provide customizable button and scroll wheel options. Some trackballs also come with Logitech's Unifying receiver, which enables users to connect multiple devices to a single USB port. Overall, Logitech trackballs offer an alternative to traditional mouse-based input and provide a range of features for different needs and preferences.
