## Summary description

Contour Design RollerMouse Pro3 is an ambidextrous ergonomic pointing device with optical movement detection and 2400 DPI resolution. It connects via USB Type‑C and is powered by cable. The unit features eight pressed buttons and a rollerbar/wheel scroll for horizontal and vertical navigation, suitable for office work, CAD, and precise cursor control.

## Long description

Contour Design RollerMouse Pro3 ergonomic ambidextrous input device is an optical pointing device with 2400 DPI resolution and wired USB‑C connectivity. The unit places a centred rollerbar directly in front of the keyboard so users can operate the cursor with either hand, reducing lateral reach and supporting a more neutral posture during extended computer work. The device includes eight press buttons and a rollerbar/wheel for smooth horizontal and vertical navigation, and is supplied with an integrated wrist rest.
Advantages
The RollerMouse Pro3 combines central rollerbar control and ambidextrous layout to minimize reaching and gripping associated with a traditional mouse. Its optical sensor at 2400 DPI provides precise cursor movement suitable for detailed tasks. Wired USB‑C power and data connection removes the need for batteries or charging. The included wrist rest and low-profile shape help keep wrists and forearms aligned, which can reduce strain during long periods of use.
Suitable for
Office productivity and general computer work
CAD and design tasks requiring precise pointer control
Data entry and spreadsheet navigation
Users seeking an ergonomic alternative to a traditional mouse

How to use
Position the RollerMouse Pro3 directly in front of your keyboard so the rollerbar is centred beneath your hands. Connect the device to your computer using the supplied USB‑C cable. Use the rollerbar to move the cursor horizontally and vertically, and operate the eight press buttons for clicks and programmable functions. Alternate hands as needed to distribute movement and maintain a neutral wrist posture. Adjust pointer speed in your operating system if required to match the 2400 DPI sensitivity.
Usage recommendations
For ergonomic benefit, keep the device centred and switch hands periodically during long sessions. Use the integrated wrist rest to maintain a relaxed wrist position and avoid excessive gripping of the rollerbar. If you require specific button assignments or pointer settings, configure them in your system preferences or any compatible driver/software to optimise workflow and precision.
