Contour RollerMouse Red Plus is an ergonomic computer mouse designed to improve comfort and efficiency while working on a computer.

It features a unique rollerbar that allows for precise cursor control by simply moving the rollerbar side to side or up and down. The rollerbar also functions as a left-click button when pressed down.

In addition to the rollerbar, the Contour RollerMouse Red Plus has several other buttons that can be customized to perform various functions, including copy, paste, left-click, right-click, scroll wheel, and double-click.

The click force and click volume of the rollerbar can be independently adjusted to suit the user's preference, and the double-click button can be reconfigured to function as a middle button if desired.
