The MX Ergo Wireless Trackball from Logitech shares many design features with the M570 Wireless Trackball. The body contours are virtually identical, with more angular lines and a metallic grey trackball to distinguish it from the M570. The differences focus on improved ergonomics and expanded functionality. The MX Ergo Wireless Trackball features a magnetic base plate on which the trackball can be angled to either 0° or 20° by a simple shift of pressure from the hand.
The MX Ergo Trackball transfers all cursor control to the thumb, which virtually eliminates arm movement when mousing. Accurate adjustable optical tracking is provided by a 380 DPI laser sensor with a thumb-activated Precision Mode button. The contoured body provides a relaxing support for the hand, naturally positioning the fingers over the right and left buttons. A rubber-coated tilting scroll wheel with crisp detents is conveniently positioned between these buttons to complete the traditional mouse control layout. The index finger has easy access to convenient Back and Forward Buttons for browsing through multiple pages of a document or web page.
The MX Ergo Wireless Trackball offers Dual Connectivity - USB via the Logitech Unifying receiver, or Bluetooth (see Detailed Specifications for compatibility details). Those working with multiple computers at a time may wish to take advantage of the "Logitech Flow" capability to connect with and work seamlessly across two separate computers.Note: As the MX Ergo Wireless Trackball places the workload fully upon the thumb, (which on most other trackballs is generally shared by several fingers), anyone who has existing thumb issues would be well-advised to consider alternative solutions.
Reduces Strain on Arm, Elbow and Shoulder Muscles
- Like a touchpad, the MX Ergo Wireless Trackball is a stationary mousing device. (Moving the ball with the thumb moves the cursor on the screen.) Limiting the repetitive movements of the arm and shoulder can greatly reduce the potential for injury and inflammation in these muscle groups. The housing of a trackball can also be angled in any direction, allowing the user to keep the elbow, wrist and hand in a straight line, and to limit ulnar and radial deviation.

Reduces Strain on the Hand, Wrist and Arm
- Trackballs effectively counter any tendency there may be to grip the pointing device too hard. This often inadvertent static grip can cause pain and injury to the muscles and soft tissues in the back of the hand and in the wrist and forearm. The MX Ergo Wireless Trackball, by requiring a simple spinning motion accomplished with the thumb, largely eliminates static grip. Learn More About Static Grip Force.
- The MX Ergo Wireless Trackball features a contoured shape which provides a natural, relaxing support for the hand.
Reduces Reach for Buttons
- The MX Ergo Wireless Trackball positions the left and right buttons as well as the scroll wheel for natural access by the fingers used on a traditional mouse. The fingers are actually able to relax against the buttons, assisting in avoiding the development of Trigger Finger. Software to customize the button functions is available from Logitech.

Can Be Used In Locations Where a Mouse Can’t

- Dual Connectivity Wireless Convenience: The MX Ergo Wireless Trackball uses a Logitech Unifying receiver or Bluetooth for connection. Minimum OS compatibility requirements are listed in the Specifications.
- Precision Optical Tracking Technology: The MX Ergo Wireless Trackball features accurate optical tracking. A Precision Mode button is conveniently located just above the trackball for use when enhanced precision is required.
- 34 mm Trackball: The 34 mm ball is easily be moved, regardless of hand size. The movement requires minimal effort so the load on the thumb is minimal. Although low effort is required, the ball still offers sufficient resistance, ensuring that a high level of control is retained. Movement is smooth and accurate.
- Natural Hand Support: The contoured body of the MX Ergo Wireless Trackball is shaped to offer support for most average sized hands. Those with very large hands might wish to consider a device with a larger supporting surface.
- Multi-Computer Functionality: Individuals with compatible computer systems can connect to 2 different computers using "Logitech Flow" for seamless workflow between systems.

- Since all cursor movement is accomplished by the thumb you should be vigilant and take notice if any pain begins to develop. Should this occur it would be wise to immediately reduce the usage or change to a device which does not require thumb movement. Most people are quite aware of carpal tunnel and often shift to trackballs as an alternative to address existing RSI issues or as a precautionary measure. However, most are not aware of the danger which can exist from overuse of the thumb. De Quervain Syndrome or De Quervain's Tenosynovitis can be as painful and debilitating as the other more commonly known RSI.

- If you are new to a trackball expect that it will take a while to get accustomed to the different style of control. It is also a good idea to limit the amount of time you use it in the first while. Rather, build up to longer periods of usage by interchanging with a different mousing device or by Load Balancing (see next point).
- Load Balance Your Use: Since the MX Ergo Plus Wireless Trackball is a dedicated right hand mousing device it cannot be switched between hands. For this reason it is a good idea to have an alternate mousing device either for either the left or right hand which can be used to give the thumb a break from continuous usage.
- Take regular breaks. If you find that you are experiencing discomfort in your thumb, especially in the learning stages - that is a good sign that you may want to take a break by switching to a different device or by swapping to the other hand. As with any device, make an effort to regularly change your usage, take breaks, and perform stretches. Some users find that the fingers can benefit from occasionally flexing them through a full range of movement, both extending and contracting them fully.
