NOTE: This mouse has been redesigned and is now called the Perfit Mouse Optical (PMO) Mouse, an optical USB device with a built in scroll wheel in the thumb rest and a two-way programmable rocker switch. For those who prefer the 'classic' design, the 'Classic' Perfit Mouse Optical (PMO5 - the unit on the right side of the picture) is also available, which does not feature a vertical scroll wheel.

View from the front. View from the side.   PMO5 (click on picture to enlarge)	Features of the Perfit Mouse: Elevated Wrist Support - Reduces pressure on the wrist by keeping it off the desk top. Maintains a straighter wrist alignment and minimizes lateral deviation. Balances the hand in a neutral, tilted posture. Prevents static grip by allowing the hand to rock freely. Sculpted Elevated Buttons - This enables the hand to remain open with the fingers extended in a ready position for quick button activation. Buttons are elevated and shaped to reduce excessive load on the fingertips - you click with the first knuckle on your hand instead of the tip of your finger, with your fingers relaxed and extended instead of curled and clenched. 800 dpi Precision Optical Tracking - Twice the tracking precision of many other optical mice. No performance degregation due to dirt buildup like 'ball' style mechanisms. Multiple Sizes for both left and right hands - The Perfit Mouse Optical is available in Small, Medium, Large, and Extra-Large for the right hand and Small, Medium and Large for the left hand. Thumb Support with Integrated Scroll Wheel & Two position rocker switch - This gives the user added support, control and comfort. Allows one to move the mouse with reduced Pinch Force which is known to increase the risk of Carpal Tunnel Syndrome. The Scroll Wheel provides scrolling and the textured, rubber coated light touch two position rocker switch provides access to additional repetitive commands. *** Note the PMO5 (Classic Perfit Mouse Optical) does not have an integrated scroll wheel) Super Light Touch: The 2 position side rocker switch uses very light touch internal switches and are designed not to require pinch force to activate. The switches 'click' with a very slight forward or backward motion of the thumb. The switch 'rocker' is rubber coated and textured to provide maximum grip, with little effort. Multiple Platforms - The Perfit Mouse Optical supports both PS/2 and USB connections, providing support for the majority of today's and older computer systems. Programmable Software - Using the drivers and software bundled with the unit allows customization of the Perfit Mouse Optical to accomplish tasks faster and easier. Set the buttons individually. Find the Perfect Fit The table below is an aid to help you determine what Perfit Mouse Optical size you will need. You should measure your hand size using a ruler and compare the result to determine the recommended size. Measure on the palm side of the hand, from the tip of the middle finger to the first wrist crease with your hand held flat, as shown in the figure below: Compare your measurement with the table below. Note: If your hand measurement is between two sizes and you have a relatively thin hand, select the larger size. If you have a thick palm you should choose the smaller of the two. Hand Size Mouse Size Imperial Metric Under 6.75" Under 17 cm Small 6.75"to 7.5" 17 to 19 cm Medium 7.5" to 8.25" 19 to 21 cm Large 8.25" and above 21 cm or greater Extra Large

Refer to the tables if you're not sure what connections are available on your system. If your computer has a USB port, Contour strongly recommends you use the native USB connection on your PMO or PMO5 rather than using the PS/2 adapter.
