The third generation DXT Mouse 3 from City Ergonomics is designed for those with average to larger size hands who may have found the DXT 2 to be a less than ideal size. It features improved contours and a new rubber thumb rest for even greater fingertip control than earlier models. This finger-controlled vertical mouse positions the hand and wrist in a relaxed natural vertical orientation. Control of the mouse is primarily achieved by employing the small muscles and joints of the fingers, with minimal involvement of the larger muscle groups of the shoulder and arm. The much greater precision attainable through the fingers makes the DXT Mouse 3 suitable for those requiring fine, precise cursor control. The DXT Mouse 3 features light click buttons to minimize the effort required for clicking and the unique ambidextrous design readily facilitates workload balancing between the left and right hands. The DXT Mouse 3 also includes convenient Back/Forward buttons and is overall larger and taller than the earlier DXT and DXT 2 models. As such it is also better suited to those with average to larger size hands. Those with smaller hands may wish to consider the wired or wireless versions of the DXT Ergonomic Mouse 2. The DXT Sizing Chart should be used to determine which DXT Mouse would be most suitable.
The DXT Mouse 3 moves with minimal resistance, requiring nominal effort to accomplish effective cursor control. The mouse is equipped with a weighted zinc base to ensure vertical stability and to optimize control by providing enhanced tactile feedback. With four DPI settings available at the touch of a button, the DXT Mouse 3 can meet the requirements for any type of work, regardless of the sensitivity and accuracy required.
The DXT Mouse 3 is also available in a convenient rechargeable Wireless version.
Eliminates Static Grip Force - When using a DXT Mouse individuals are able to lightly hold the mouse between the fingers and thumb. In fact, movement is actually easier to perform when less pressure is applied. Once this reality is realized it is possible to greatly reduce the level of force being exerted, eliminating the need to "grip" the mouse. Learn More about Static Grip Force When Using the Mouse.
Encourages Load Balancing - The convenient ambidextrous design of the DXT Mouse means that switching between left and right-handed use throughout the day is virtually effortless. This can be beneficial both in avoiding potential RSI-producing overuse by one hand and arm as well as a means to accommodate graduated usage redistribution during rehabilitative therapy.
Reduces Pronation - The pen-like orientation of the DXT Mouse rotates the forearm out of the pronated position required by standard mousing devices. This can reduce the risk of developing pronation-related issues such as Tennis Elbow. It also eliminates much of the Wrist Extension which tends to occur when using a traditional "palm down" mouse. Learn More About Pronation.
Reduces Risk of RSI in Shoulder - The design and usage of the DXT Mouse 3 significantly reduces the amount of movement required from the shoulder, especially the "overreach" which is common when using a traditional full-size keyboard and mouse. Learn More about Overreaching Outside of the Comfort Zone.
Ambidextrous Design: The symmetrical design of the DXT Mouse allows use by either the right or left hand. This feature means that the DXT can be used to aid in recovery from or to potentially prevent upper limb disorders.
Compact Ergonomic Design: Since it is held primarily through the fingertips and controlled by the fingers, finger length and palm size are less of a concern with the DXT Mouse than with more traditional designs. However, the DXT Mouse 3 is broader, wider and taller than the DXT Mouse 2 and therefore better suited to those with average or larger hands. The larger dimensions position the buttons and thumbwell at a height that naturally matches larger hands. The more "pen-like" movement is natural to most people, requiring minimal adjustment to the method of movement. The compact size and minimal degree of movement required makes the DXT well-suited to mobile usage or deployment where limited space is available. The DXT Sizing Chart should be used to determine which model of the DXT Mouse would be most suitable.
Precision Grip Design: The DXT Mouse 3 has an optimized fingertip grip that facilitates a relaxed hand while still offering a high degree of control. This control is enhanced by a rubber grip in the recessed thumbwell. The shape and size of the DXT Mouse 3 are what permits the thumb and fingers to work together to facilitate higher accuracy and performance. The DXT takes advantage of the higher sensory input afforded by fingertips and thumb, input that traditional palm-controlled mouse designs cannot provide.
4 DPI Settings: The selectable resolutions permit quick cursor speed changes to accommodate the varying demands of different tasks.
USB Connection Plug and Play: No software to install. The DXT Mouse 3 lets you get started quickly.
Optional Programmable Driver: The downloadable driver offers the option of custom programming up to 7 button functions to personalize the mouse for individual needs.
Light Click Buttons: The DXT Mouse 3 features Light Click Buttons to reduce the effort required to perform Left and Right click functions.
Textured Scroll Wheel: The rubberized textured wheel features soft detents but scrolls with minimal effort.
Weighted Base: The DXT Mouse 3 has a zinc base that ensures stability as well as offering the weight necessary to provide the tactile feedback necessary for accurate fingertip control.
Wired and Wireless Options: The DXT Mouse 3 is available in both Wired and Wireless models.

Hold the DXT Mouse lightly between the thumb and fingers. Employing a high degree of pressure will actually limit the amount of control you have over the mouse, leading to a desire to exert even more pressure in an effort to achieve the desired result. This results in an unhealthy amount of "static grip force" and will also leave you frustrated with the mouse. A light touch on the mouse will permit the thumb and fingers to move the mouse easily to achieve fine levels of control but it may take time to train yourself away from the old habits of gripping a mouse more firmly. If you find that your hand is hurting or that you are unable to achieve fine control you may well need to relax your hand.
Load Balance your usage throughout the day by regularly switching between right and left hands. Not only does this reduce the load borne by a single hand, it can also stimulate the brain as the non-dominant hand learns to accomplish movement that until now may not have been required of it.
Consider switching to a Compact Keyboard. If you do not require the numeric keypad or can train yourself to utilize the "upper rank" numeric keys you should consider a compact keyboard which can reduce the reaching to the mouse. The design of the DXT Mouse already addresses this to a degree but eliminating additional unnecessary reach is always worth considering.
Take Regular Breaks, especially in the learning stages. Overworking any part of the body can result in RSI but because computer use puts an exceptionally high load demand on the hands they are more susceptible to this overuse. Load Balancing is one way of addressing this but not all users will be able to achieve sufficient control with both hands. Anytime you begin to experience discomfort you should either consider a hand changeover (if it is possible) or take a break and perform some other work or even do some hand stretches and flexing.
