Perfit Mouse Optical PS2/USB Combo with Scroll Wheel - Small Right Handed. Introducing the New Perfit Mouse Optical (PMO) and Perfit Mouse Classic Plus (PMO5). Evolving from the original patented shape, the new versions maintain the ergonomic integrity of the time-tested form while adding new productivity enhancing features. The original Perfit Mouse, introduced in 1995, has provided over 100,000 users with unparalleled comfort and performance. Years later, the Perfit Mouse continues to be highly recommended by safety specialists, health professionals and ergonomists. In many instances, the Perfit Mouse is the only solution for eliminating or reducing hand and wrist discomfort while maintaining a high level of productivity. Proactive companies use the Perfit Mouse on mouse intensive workstations because it is highly effective in preventing mouse related injuries. What's the secret? Through years of testing we have discovered a unique posture for the fingers, thumb and palm that is not only great for rapid target acquisition, but also allows maximum muscle and tendon variation throughout point and click operations. Variation is only one of the keys. We also found that when the hand is placed in this balanced posture, local hand muscles come into play. This minimizes the need for flexor muscles that are connected to the fingers through the carpal tunnel. Reduction of carpal tunnel activity is the key to preventing carpal tunnel syndrome. The new optical versions add the latest technology to the unique design of the original Perfit Mouse. A high precision optical sensor provides excellent cursor control. The Perfit Mouse Optical (PMO) places a scroll wheel above the thumb support, rather than on the top of the mouse to reduce the strain on the index finger, which is already heavily used for the primary mouse click. At the bottom of the integrated Thumb Support is the innovative two-position side rocker switch which gives quick and effortless access to two additional programmable buttons.
Features:

• 800dpi 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 Optical Mouse is available in Small, Medium, Large, and Extra-Large for the right hand and Small, Medium and Large for the left hand.
• 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.
• Thumb Support with Integrated Scroll Wheel & Two position rocker switch (Perfit Mouse Classic Plus models do not have Scroll Wheel) - This gives you the user added Support, Control and Comfort. Allows you 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. (See Important side note.)
• 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.
• Multiple Platforms - The Perfit Optical Mouse support both PS2 and USB connections, providing support for the majority of todays and older computer systems.
• Programmable Software - Using our software enables you to customize the Perfit Mouse Optical and accomplish tasks faster and easier. Set the buttons individually.
