3DConnexion CadMouse Pro Mouse - Optical - Cable - 7 Button(s) - Black

The Button for CAD Professionals The middle mouse button is designed specifically for CAD users who require a third button to access their application functions. Using less force than a scroll wheel click, the middle mouse button is ideal for CAD applications. More Comfort, Less Strain Designed with an angled shape, CadMouse Pro creates a more natural hand posture, reducing the muscle and tendon discomfort frequently encountered with traditional mice. The Ideal Thumb Rest Complementing its slanted shape, the incurvated thumb rest gives thumbs an ergonomically natural place to hold onto the mouse and easy access to its side buttons.
