The Orbit Optical Trackball from Kensington is an ambidextrous alternative to traditional mice which require a constant grip to be used and a larger amount of space on the desktop. The 40 mm trackball utilizes optical tracking for accuracy and is centrally positioned for ease of movement by the fingers. Left and Right buttons are located adjacent to the ball, with the thumb and pinkie fingers naturally dropping into position over them. The Orbit Optical Trackball is sized to best fit the needs of those with small to average sized hands. Individuals with larger hands may wish to consider one of the larger trackball options.

Note: Those who perform large amounts of scrolling need to be aware that the Orbit Optical Trackball does NOT have a mechanism to perform vertical scrolling and should consider a trackball which includes a dedicated scroll wheel or ring such as the Orbit Optical Trackball with Scroll Ring.

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 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 Kensington Pro Fit Ergo Wired Keyboard features a winglike design that orients the alphanumeric keys at approximately 11° with the navigation and keypad keys being at 0°. This sloping of the keys reduces pronation of the hands and forearm while typing. The left and right key groups are also splayed outwards at 33° to encourage a more neutral alignment and reduce ulnar deviation at the wrists. The integrated palm support on the Pro Fit Wired Keyboard is just over 3" in depth, and offers cushioning for the palms. It is covered in a leatherette material that is easily cleaned.

The angle and height of the Pro Fit Ergo Wired Keyboard is such that the wrists are supported in a fairly neutral alignment when the elbows are about 1" below the desk surface. For those who would rather sit at a more ergonomic height (i.e. elbows at or just above desk height) and benefit from a slight improvement in wrist alignment there are legs built into the underside of the palm support. When deployed these elevate the front to create a nominal 4° negative slope. When the keyboard is flat the highest point on the keys is 1.4" and with the negative elevation legs deployed the highest point is 1.9".

The island-style keys are fairly quiet but it should be noted that they have a moderately high peak operation force of 55 grams, which over time can cause fatigue and strain on the fingers. As well, the inner columns of keys are wider to create a more appealing look but this can lead to inadvertently striking the keys off-centre. When struck to the edge there is a tendency for these keys to partially bind, thus requiring more force to complete the key activation. This could lead to dropped keystrokes and an overcompensation response of exerting a higher degree of force to ensure activation. With a limited travel distance of just 2.5mm this will likely lead to the fingers impacting at the end of each keystroke.

Le Kensington Pro Fit Ergo Wired Keyboard est en forme d'aile (winglike design) qui oriente les touches alphanumériques à environ 11°, les touches de navigation et du pavé numérique étant à 0°. Cette inclinaison des touches réduit la pronation des mains et des avant-bras pendant la dactylo. Les groupes de touches gauche et droite sont également ébrasés vers l'extérieur à 33° pour favoriser un alignement plus neutre et réduire la déviation ulnaire au niveau des poignets. Le support de paume intégré sur le Pro Fit Wired Keyboard mesure un peu plus de 3po de profondeur et offre un rembourrage pour les paumes. Il est recouvert d'un matériau en similicuir facile à nettoyer.

L'angle et la hauteur du Pro Fit Wired Keyboard sont tels que les poignets sont soutenus dans un alignement relativement neutre lorsque les coudes se trouvent à environ 1po sous la surface du bureau. Pour ceux qui préfèrent s'asseoir à une hauteur plus ergonomique (c'est-à-dire les coudes à la hauteur du bureau ou juste au-dessus) et bénéficier d'une légère amélioration de l'alignement des poignets, il y a des pieds qui sont intégrés sous le support de paume. Lorsqu'ils sont déployés, ils élèvent l'avant pour créer une pente négative nominale de 4°. Lorsque le clavier est à plat, le point le plus haut des touches est à 1.4po et lorsque les pieds d'élévation négative sont déployés, le point le plus haut est à 1.9po.

Les touches de style "island" sont assez silencieuses, mais il devrait être noter qu'elles ont une force de frappe significativement élevée de 55 grammes, ce qui, après un bout de temps, peut causer de la fatigue et des tensions sur les doigts. Également, les colonnes intérieures des touches sont plus larges pour créer un apparance plus intéressant, mais cela peut causer de frapper les touches sur le côté par accident au lieu du centre des touches. Lorsque les touches sont frappées sur le côté, elles ont tendance à se coller partiellement, ce qui nécessite une plus grande force pour compléter l'activation de la touche. Cela peut causer les caractères d'être perdus et une réponse excessive qui nécessite plus de force pour assurer l'activation de la touche. Avec une distance de déplacement limitée à 2.5mm, les doigts risquent d'avoir la vibration/choc de l'impact à la fin de chaque frappe.

The Pro Fit Ergo Wireless Keyboard is able to connect either via Bluetooth 4.0LE or the included 2.4GHz wireless receiver (replaceable if lost) which employs 128-bit AES government-grade encryption for security. The connection is switchable via a switch on the underside that also serves as a power switch.

The Expert Mouse Wired Trackball will fit most hands. However, if a user has a small hand they may wish to consider the Orbit Trackball with Scroll Ring which features a smaller 40 mm trackball and is better suited for smaller hands.

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.
