Perfit Mouse Optical


Contour Design


Product Description

Product image 200x100

The Perfit Mouse Optical from Contour Design is an ergonomic mouse designed for workstations that require above average clicking or cursor movement. The contoured shape of the PMO ‘perfectly fits’ your hand, no matter what size it is or whether you are right- or left-handed. This ‘perfectly fitted’ mouse allows the hand to easily control the basic functions of the mouse while reducing any fatigue that would otherwise result from constantly using a uniformly shaped or ambidextrous mouse. With the PMO, the mouse is meant to perfectly fit your hand, not your hand the mouse. This design principle is just good ergonomics put to effective use.

Highlights include:

Reasons to Choose the PMO over the CMO Easier to slide your hand between Mode 1 and Mode 2 usage, easier to clean / sanitize.
Reasons to Choose the CMO over the PMO Less likely to slip your hand back off the mouse by accident and be forced to 'grip' the mouse, less potential for grip force

  • If your computer has a USB port, we strongly recommend you use the native USB connection on your PMO or PMO5 rather than using the optional PS/2 adapter which is only available by special request.
  • Contour mice work with the operating system's (OS) built-in drivers on all of the ports shown.
  • Contour Design provides drivers with additional features for each of the OS/port combinations highlighted.
