It may look a little strange but the Natural Ergonomic Keyboard 4000 places your wrists in a more natural alignment so you can work more comfortably. With the unique wrist riser attached, the front edge of the keyboard is raised so your wrists get better support. Includes a 4-button mouse with four-way tilt wheel. Includes a PS/2 adapter for the USB mouse. Requires Microsoft Windows 2000/XP/Vista.
