The Pro Fit Ergo Vertical Wireless Mouse from Kensington presents with a body angle of approximately 47°. A short flange keeps the side of the hand clear of the surface but still permits most of the little finger to make contact during movement. This wireless mouse is contoured specifically for right-handed use and operates plug-and-play. However, optional drivers are available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch accommodates quick access to four DPI settings (800, 1000, 1200 and 1600) to accommodate different work requirements. The wireless receiver offers an impressive 20 metre range and can be stored in the underside of the mouse to ensure it isn't misplaced. The scroll wheel is spherical and has a lower protrusion from the body of the mouse than most traditional scroll wheels with rotation being possible using the side of the fingers. Detents provide clear feedback but the smaller diameter of the scroll "sphere" seems to require a greater degree of force than most traditional "wheel" designs.

The size of this mouse means it is best suited for smaller to average sized hands. The body is narrower than most vertical mouse designs, which can lead to a tendency to want to "grip" the mouse which has the potential to lead to exerting unnecessary static grip force.
Note: While being identified by the manufacturer as a "vertical" mouse this angle is substantially less than most other "vertical" mousing products, the majority of which orient the hand well above 60° and therefore much closer to a truly vertical presentation.

The Pro Fit Ergo Wireless Mouse from Kensington presents with a body angle of approximately 40°, rotating the hand away from a traditional fully prone position. This wireless mouse is contoured specifically for right-handed use and operates plug-and-play. It is able to connect via either standard 2.4 GHz wireless with the included receiver dongle, or through Bluetooth 4.0 with devices that can support this option. A switch on the underside changes mode and doubles as a batter-saving power switch. Optional software is available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch just behind the scroll wheel accommodates quick access to three DPI settings (800, 1200 and 1600) to accommodate different work requirements. The wireless receiver can be stored in the underside of the mouse to ensure it isn't misplaced. The scroll wheel has detents to provide clear feedback response. The click action is somewhat soft and very quiet. This lack of tactile and auditory feedback may make it difficult to determine when clicks have truly activated and may lead to a greater degree of force being exerted, resulting in unnecessary stress on the fingers.

The size of this mouse means it is best suited for smaller to average sized hands as those with larger hands will find their palm either unsupported or their fingers extending past the end of the buttons, with the "inset" of the buttons into the body of the mouse making it difficult to perform clicks. The body is fairly narrow as well, encouraging "gripping" rather than permitting larger hands to relax.

The Pro Fit Left-Handed Ergo Wireless Mouse from Kensington presents with a body angle of 41°, rotating the hand away from a traditional fully prone position. This wireless mouse is contoured specifically for left-handed use and operates plug-and-play via standard 2.4GHz wireless with the included receiver dongle. Optional software is available for both Windows and Mac OS should one desire to customize the button functions. A convenient DPI switch just behind the scroll wheel accommodates quick access to three DPI settings (800, 1200 and 1600) to accommodate different work requirements. The wireless receiver can be stored in the underside of the mouse to ensure it isn't misplaced.

The Orbit Fusion Wireless Trackball from Kensington features a contoured body that supports the hand in a naturally relaxed position, rotated outwards at approximately 40°. The large 40 mm trackball provides silky-smooth and virtually effortless cursor control and is positioned so that multiple fingers can share the workload. Three DPI settings are available, a fixed 400 DPI for fine control and two dynamic ranges of 400-800 and 800-1500 DPI that respond to the rate of the trackball rotation to provide both speed and control. Speed adjustment is achieved via the thumb switch. A convenient patented light-action detent-free scroll ring around the base of the trackball gives quick access to scrolling and for viewing lengthy documents a quick press of the thumb on the middle-click button converts the trackball to scroll function. On the thumb side are conveniently-placed Left Click, Middle Click, Back and Forward, and DPI buttons. A large right-click button is positioned to the right of the trackball for access by the ring finger.

Since the Orbit Fusion connects wirelessly and can be placed on any surface - even soft or uneven ones, this a great mousing option when working on a Smart TV. The 2.4 GHz wireless receiver connects via USB-A or USB-C (using the included adapter) for laptops or devices that do not include full-size USB ports. Basic functions are available plug-and-play but can also be customized using the KensingtonWorks software (Windows and Mac)

Those who in the past may have used the Microsoft Explorer or Logitech TrackMan Marble FX trackballs may find the Orbit Fusion Wireless Trackball to offer a degree of similarity to these discontinued devices. The overall angle, hand placement and finger control are similar and are now combined with improved overall function and performance.

The Newtral2 Mouse from Microtouch offers new features and improved performance over its predecessor while still retaining all of the features of the original. Designed to support the palm and thumb, the body of the Newtral2 Mouse encourages users to rest their hand on the mouse rather than trying to grip it. The 33° outward angle of the mouse body helps to reduce pronation of the forearm, a common risk factor for fatigue and pain in the forearm and hand.

Three interchangeable flanges provide a surface for the little finger and outer edge of the palm to rest on, reducing friction and drag. The largest flange is a new addition to the Newtral Mouse family. This flange elevates the side and heel of the hand, as well as the wrist, with an integrated gel pad providing comfortable support. This new 'Ergo-Grip' configuration eliminates the need to maintain a grip on the device. Instead, the hand is held in position by gravity, and moves with the device.

The Newtral2 Mouse is available in sizes Large and Medium, and in wired and wireless models. Both wired and wireless models offer fingertip access to multiple DPI settings (see detailed specifications for details) enabling users to choose the pointer response best suited to their needs. The wired model is programmable (on Windows only), and ships with a Windows driver CD to allow users to reprogram all six buttons.

The Newtral2 Mouse is available for right-handed use only. Use this convenient Sizing Guide to assist in choosing the appropriate size of Newtral2 Mouse.
Please Note: The Newtral2 Mouse is now discontinued and has been replaced by the Newtral 3 Mouse.

The Lift Vertical Mouse from Logitech is styled after the larger MX Vertical Advance Ergonomic Mouse. The Lift, designed specifically for small to medium-sized hands, offers the same fixed 57° to reduce the risks associated with pronation of the forearm. The angled body is designed to provide some support necessary for the hand to "relax" while engaged with the mouse.

The Lift Vertical Mouse is equipped with a top quality sensor capable of reading from 400 - 4000 DPI. With a nominal setting of 1000 DPI, the Lift can be adjusted anywhere within the range in 100 DPI increments. The DPI button, just behind the scroll wheel, offers easy access to dpi adjustment for basic or fine control movements. The scroll wheel has a rubber tire for grip and features distinct but soft detents, with the operation almost silent. There are 5 programmable buttons (left, right, back, forward, & middle click).

The buttons on the Lift feature a light curvature to facilitate a more natural curl to the fingers and to provide more control. The left and right buttons require low effort to activate and are almost silent, with the tactile response being a better indicator of switch activation than the sound. However, the hard plastic of the buttons could lead to pinching the mouse between the thumb and fingers in an attempt to achieve a better sensation of control.

The Lift Vertical Mouse offers 2 wireless connection options: 2.4Ghz Logi Bolt Receiver with an operation distance up to 33 feet, and Bluetooth (Bluetooth Low Energy Technology required). It is powered by a single AA battery that the manufacture claims can provide up to 24 months of use (of course, individual usage may affect this). Using Logitech "FLOW" it is possible to connect with and control up to 3 computing devices using a single mouse.

The StudioMouse Wireless from Kensington is an ambidextrous wireless mouse that features touch scrolling rather than a traditional scroll wheel. Scrolling is accomplished by swiping the finger up or down the touch zone or holding the finger down for continuous scrolling. A middle button just above the touch zone supports auto-scrolling as well. The wireless receiver and charging station connects via USB (for data communication) and a standard wall adapter (for charging). The ambidextrous design makes this suitable for right- or left-handed use. The small dimensions of this mouse (4.5"L x 2.5"W x 1.25"H) make this best suited for those with smaller or average size hands.

This mouse is New Old Stock so the included NiMH rechargeable batteries are untested. However the mouse can use standard AAA batteries. It has been tested and verified to fully function under current versions of Windows.

This was the wireless version of the popular Evoluent VerticalMouse 3. It used a 2.4 GHz wireless method of transmission with a 30' range and estimated 3 month battery life. The wireless model featured a fixed 1200 DPI optical sensor and had the same shape as the corded model. This wireless mouse came in a right-handed model only, with a black housing and smoke (dark silver) buttons, with minimalist environmentally-friendly packaging.

Although the VerticalMouse 3 Wireless is now discontinued it has been replaced by the VerticalMouse 4 Wireless and VerticalMouse D Wireless, both of which offer the same vertical orientation but now with improved ergonomic contours, multiple sizes, adjustable DPI, and expanded features.

With Logitech's Performance Mouse MX you can track virtually anywhere - even on a glass desk - with Logitech Darkfield Laser Tracking. Turn the world into your mouse pad. This new mouse also incorporates the Logitech Unifying receiver - the tiny, wireless receiver that stays in your notebook and lets you add devices as you need them. Plug it. Forget it. Add to it.

The micro-USB recharging system lets you use the mouse even when it's charging. You'll fly through documents and Web pages with a single spin. Click-to-click scrolling gives you the precision you need when navigating lists, slides, and images. Designed to fit your hand and put it in a comfortable, natural position, the Performance Mouse MX also has customizable thumb buttons to help you do more, faster. Move backward or forward through Web pages, zoom in or out on photos, and jump between open windows.

Note: Although this is the recommended replacement for the MX Revolution Mouse, the revised shape makes one's hand more pronated (i.e. flatter) on this version than the old MX Revolution Mouse.

The Pro Fit Ergo Vertical Wireless Trackball from Kensington offers thumb-operated cursor control that eliminates the traditional arm and hand movement required with a traditional mouse. It also moves the hand and forearm away from a prone position by angling the hand outward at 60°. The 34mm trackball offers silky-smooth movement with adjustable optical tracking from 400-1500 DPI. The contoured body provides a support for the hand, naturally positioning the fingers over the right and left buttons. Side scrolling function is provided by a tilting scroll wheel that features crisp detents, 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 Pro Fit Ergo Vertical Wireless Trackball offers Dual Connectivity that can simultaneously support connections to up to 3 computers or devices (1 via the included 2.4 GHz receiver and up to 2 more via Bluetooth.

As the Pro Fit Ergo Vertical 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.
