The MX Vertical Advanced Ergonomic Mouse from Logitech is their first attempt at offering a mouse which more aggressively reduces pronation than other mice in their line. The body of the MX Vertical is angled at a fixed 57° to reduce the risks associated with pronation of the forearm. The angled body is designed to provide the support necessary for the hand to "relax" while engaged with the mouse. However, those with smaller or narrower hands may find that they need to maintain a degree of tension to hold their hands "up" in position over the buttons. Large or wide hands will likely have less of a problem with this requirement to maintain hand position.

The MX Vertical is equipped with a top quality sensor capable of reading from 400 - 4000 DPI. Two nominal settings of 1000 and 1600 DPI can be adjusted anywhere within the range in 50 DPI increments. The top-mounted DPI button enables users to adjust the mouse as needed for basic or fine control movements. The scroll wheel has a rubber tire for grip and features distinct but soft detents. There are 4 programmable buttons (left, right, back, & forward).

The MX Vertical offers 3 connection options: Wired via the charging cord, 2.4Ghz Logitech Unifying Receiver with an operation distance up to 33 feet, and Bluetooth (Bluetooth Low Energy Technology required). The 270mAh Li-Po rechargeable battery can provide up to 4 months use on a single charge and offers a 1 minute Quick Charge that can provide up to 3 hours of use. Of course, individual usage may affect this. Using Logitech "FLOW" users are able to connect to and control up to 3 computing devices using a single mouse.

The "flatness" of the buttons on the MX Vertical prohibit the fingers from achieving a fully relaxed and naturally curved "position of function". This factor, combined with the almost slick surface on the buttons could lead users to try to "pinch" the mouse between the thumb and fingers in an attempt to achieve a better sensation of "control". In addition, to minimize the activation force on the buttons the fingertips need to be as close to the end of the buttons as possible. Those with large hands or very long fingers may be able to achieve this position but most users will find their fingertips falling short of this "optimum" position, resulting in a higher force being required for click activation.

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 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 Penclic Mouse (3rd Generation) provides an effortless and intuitive way to move the cursor with fine precision by employing motions similar to those used when writing with a pen. The pen can freely pivot in a recessed circular depression (ball/socket joint) on the base, allowing the user to find the best angle and orientation of the pen to maximize comfort and precision. The base itself glides to provide mouse control, and the movement of the base is achieved by using the small muscles and joints of the fingers as opposed to the larger muscle groups of the shoulder and arm. As the orientation can accommodate a wide range of positions, the user is able to move the mouse with either fine or gross movements (and accompanying positions) which can help to reduce any one set of repetitive movements. The design of the Penclic Mouse (3rd Generation) is also ambidextrous, enabling the user to easily balance the workload between the left and right hands. A number of improvements were made on this latest Penclic such as moving the scroll wheel onto the pen for easier access and better control. The buttons have also been simplified and are more intuitive and easy to use.

The 3M Ergonomic Mouse (formerly the Renaissance Mouse) features a unique, vertical grip design which largely eliminates pronation. It is ideal for those who have limited articulation of their fingers and need to 'hook' their hand onto a mouse. The mouse is for right handed individuals only and available in both a wired and wireless model.

La 3M Ergonomic Mouse (connu auparavant comme la souris Renaissance Mouse) a une charactéristique unique qui est une prise verticale qui élémine la pronation de grande façon. Elle est idéale pour les usageurs qui veulent l'articulation minimale des doigts et qui veulent avoir une sensation d'accrocher la main sur une souris.

The CST3645 Vertical Mouse allows the hand to adopt a nearly vertical (approximately 60°) hand position while mousing. The unit has raised 'ridges' where the hand and thumb make contact with the mouse to prevent pockets of heat from forming when using the mouse for extended periods of time. The thin contoured left and right click buttons are on the right side of the mouse (with a clickable vertical scroll wheel nested between), and two convenient thumb buttons perform Back and Forward actions. There is a dpi toggle on top of the mouse to adjust between 600, 1000 and 1600 dpi. A removable palm support 'surround' at the rear of the mouse prevents the edge of the hand from dragging on the surface when moving the mouse, encouraging mouse movements to be made with the entire arm. The Superior-X driver is available to allow reprogramming of all the buttons.

The R-Go Break HE Ergonomic Mouse from R-Go Tools is a proactive model of the HE Ergonomic Mouse which includes customizable "Break Reminder" software and a coloured visual reminder on the mouse. The Break model features the same design and functionality of the other HE Ergonomic Mouse models, rotating the hand upward and outward. This angled posture reduces strain on the tissues of the forearm when compared with the traditional pronated "palm down" position. In addition, because the hand is now elevated up and away from the surface, users are no longer able to "plant" the heel of their hand in the manner that the traditional mouse position encourages. This virtually eliminates the potential for the development of RSI from repetitive or sustained wrist extension.

The customizable "Break Reminder" software provides a mechanism for users to set the duration and spacing of break periods as a well as a maximum daily use. The software monitors computer activity and changes the logo colour between Green (Good), Orange (Break Reminder), and Red (Break was skipped or daily usage limit exceeded).

The R-Go HE Ergonomic Mouse is also available in a standard Wired model as well as the Wireless model for cord-free convenience.
Note: When selecting the appropriate size of R-Go Mouse the hand should be measured from the tip of the middle finger to the first crease in the wrist.

The R-Go HE Sport Ergonomic Mouse from R-Go Tools rotates the hand upward and outward. This angled posture reduces strain on the tissues of the forearm when compared with the traditional pronated "palm down" position. In addition, because the hand is now elevated up and away from the surface, users are no longer able to "plant" the heel of their hand in the manner that the traditional mouse position encourages. Thus, the potential for the development of RSI from repetitive or sustained wrist extension is virtually eliminated.

The R-Go HE Sport Ergonomic Mouse offers support for the hand and fingers, encouraging users to let their hand relax against the natural contours. The R-Go HE Sport is sized to accommodate hand sizes ranging from 6.5" to 7.3" in length, is available in both Left and Right. It is equipped with a 4-level sensor that can read from 800-2400 DPI.

The R-Go HE Sport Ergonomic Mouse features a striking red body with contrasting silver buttons. The highly textured thumbrest ensures firm control but users with high sensitivity may find the braille-like nodules less than comfortable. Connectivity is via Bluetooth so this model will only connect with computers that are Bluetooth-enabled. For non-bluetooth environments there are both Wired and a 2.4 GHZ Wireless models available. The wired BREAK model provides also visual cues to remind users to take regular breaks in order to reduce the risk of developing RSI.
Note: When selecting the appropriate size of R-Go Mouse the hand should be measured from the tip of the middle finger to the first crease in the wrist.

The Penclic Mouse from Penclic is an elegant precision mouse using a 'pen-shaft' design to make moving your cursor as easy as writing with a pen. Mouse buttons are on the pen-shaft for quick access, while there is a scroll wheel on the base. Available in wireless or corded models.

The Rockstick Mouse offers an ingenious alternative to address the single most repetitive activity while using a computer - generating left mouse clicks. Instead of clicking a button, the user need only 'rock' the 'stick' portion of the mouse (tilting it slightly to the left for a left click, and to the right for a right click). Finally, users can mouse without lifting a finger! This makes this mouse a potentially good alternative for individuals with trigger finger, arthritis, or anyone who has difficulty clicking when using the mouse by allowing individuals to use the muscles in their entire hand to click instead of being limited to the strength and endurance of a single finger.

The base of the mouse supports the hand and provides control of the mouse without the need to 'grip' the mouse. The vertical orientation of the Rockstick also eliminates pronation which is the rotation to a palm down position which for some people can also lead to discomfort while mousing.

At the top of the stick is a vertical scroll wheel which can be clicked to generate middle clicks. The Rockstick Mouse comes in two sizes, a Small/Medium size and a Large size, and is corded.

La Rockstick Mouse offre une alternative ingénieuse pour adresser l'activiter du répétition unique pendant l'usage de l'ordinateur - générer les clics gauche du souris. Au lieu de faire le clic avec un bouton, vous avez seulement besoin de faire un mouvement "rock" the "stick" du souris (la pencher ce portion du souris légèrement à la gauche pour avoir un clic gauche, et la pencher à la droite pour avoir un clic droite). Finalement, vous pouvez bouger une souris sans lever un doigt! Cela donne cette souris une alternative potentielle pour des gens avec des mal douleurs trigger finger, ou l'arthrite, ou n'importe qui qui a de la difficulté a faire un clic avec une souris en utilisant le muscle dans le tout de la main pour faire le clic au lieu d'être limiter de force et endurance d'un doigt seul.

La base du souris support la main et offre le control sans le besoin de serré la souris. L'orientation vertical du souris Rockstick vient en deux tailles avec fil, un petit/moyen et un grand.
