Kensington Expert Mouse Wireless Trackball Review

Anyone who works in an office or works with computers is familiar with a computer mouse. Without a mouse, all of us would find it quite difficult to navigate our way around the computer screen. While we’re all familiar with the regular mouse, a type of mouse that not all workers are familiar with is a trackball mouse. 

A trackball is an ergonomic peripheral that’s mostly used by those who wish to prevent wrist injury or those who already suffer from wrist or shoulder troubles. Today, we’ll be taking a look at the Kensington Expert Mouse Wireless Trackball. If you’re beginning to experience wrist issues or if you’d like to avoid any wrist discomfort, maybe this trackball will suit you.

Are Trackball Mouses Better?

A trackball mouse has several advantages over a standard mouse. While they perform the same tasks, trackballs work differently. Implied in its name, trackballs have rotating balls on the top or sides that a user rolls when they want their pointer to go somewhere or do something. Most trackballs are either operated by thumb or fingers, but there are also models that can be controlled using the palm of the hand. 

Trackballs are great for both left and right-handed individuals as they can be used in the same way. All one has to do is to program the buttons to suit their needs, no matter which hand is used. A standard mouse can cause physical strain to the user. A trackball, on the other hand, only requires the user to move the large ball and not the mouse itself. Since one only needs to move the ball to operate the pointer on the entire screen, it remains in one spot, unlike a regular computer mouse. Additionally, because it doesn’t have to be moved around, a user doesn’t need to have a wide surface area despite the large size of a trackball. 

Trackballs are also more favored by graphic designers due to their precision and accuracy. Due to that, a lot of artists have traded in their Wacom Tablet for trackballs. They’re also popular with gamers as they offer fluid consistent movement. 

Is a Trackball Better For Carpal Tunnel?

While there are no products that can completely prevent carpal tunnel syndrome, there are items that can help reduce the risk and provide relief as well, such as vertical mice or trackballs. Unlike a regular computer mouse that needs your hand to move it across your workspace for you to reach your desired position on the screen, trackballs don’t require to be moved across the desktop. 

A trackball is seen as less fatiguing for some tasks, allowing it to be used by people who have conditions such as arthritis or carpal tunnel syndrome. By using a thumb-operated trackball or a finger-operated trackball, you’ll lessen the strain on your wrist and arm.

About the Kensington Expert Trackball Mouse




Expert Mouse Wireless Trackball

Product Dimensions55mm (Trackball diameter)

A trackball may look odd to anyone who’s never used it. After all, we’re so used to the standard mouse that has two buttons for clicking and a scroll wheel in the middle while a trackball is a mouse with a huge ball sitting either in the center or on the side of the body. Despite how odd it may look, a trackball can aid you in a lot of ways. 

The Kensington Expert Trackball is an ergonomic alternative for those who suffer from wrist pain and other issues due to using a typical computer mouse. Many mouse reviews on the world wide web consider this as one of the best trackballs around. Let’s get into its specifics to find out why.

Kensington Expert Mouse Trackball Features

The first prototype of a trackball was invented way back in 1952 with a bowling ball acting as the control. Thanks to the development of technology, we’ve come a long way from having an immensely large ball to a marginally smaller ball that fits better with our hands. The Kensington Expert Mouse Wireless, with its bright, red ball that’s almost the same size as a billiard ball, provides relief from wrist strains and more. Check out its highlights:

Ergonomic Design

The Kensington Expert Mouse Wireless is a rather large device, but don’t let its size deter you. It has an ergonomic, symmetrical design and a simple grid layout that allows you to use it in a natural and comfortable manner once you’re suited to your preferred hand placement. At the center of the mouse cradle sits the large ball, and it’s surrounded by a scroll ring and four buttons. 

The big trackball, designed as a perfect sphere for exceptional precision,  is smooth to the touch despite its size and weight. Its ambidextrous design allows it to be used by right-handed or left-handed people. Moreover, the Kensington Expert comes with a detachable wrist rest for extra support.

Great Build Quality

With over 40 years of expertise in the industry, it’s not a wonder that Kensington produced the Expert Trackball with excellent build quality. The Expert Mouse Wireless is constructed with premium plastic materials, making it a sturdy and robust wedge. It even has small rubber feet on the bottom of the base, ensuring that it doesn’t move across your desk when in use. 

The scroll wheel is made out of solid rubber that turns very smoothly. There is also the detachable wrist rest that is comfortable yet firm, offering good support. It makes use of leatherette for its cover and while it may not be plush, it’s soft and thick enough to ensure that your wrist and hand stay in an ideal position to reduce pain, even during long sessions.

Four Programmable Buttons

The Kensington Expert Wireless features four buttons that you can program to your liking. The buttons are springy, unlike most mice out there. With the use of the KensingtonWorks Software, you can adjust things such as pointer speed, scrolling speed, command it to launch applications, and such. You can also set combination keys for the two top buttons and the two lower buttons, giving you a total of 6 button commands according to your preference. 

For example, if you own a Mac, you can set the top two buttons to activate Mission Control or the Launchpad. It’s worth noting that you don’t have to press both buttons in the same second either; Kensington’s software is great enough at distinguishing clicks.

Dual Wireless Technology

While Kensington also has a wired version of the Expert mouse, the wireless model raises its usability to a whole nother level. The Expert Mouse Wireless Trackball has dual wireless technology, allowing you to connect via Bluetooth or through a 2.4GHz USB nano receiver. Simply toggle the switch on the bottom of the device to activate the Bluetooth mode. 

As for the USB dongle, you’ll find it stored on the bottom of the device, behind the battery door. The receiver is plug-and-play and already paired with the Expert Mouse Wireless Trackball. Simply toggle the switch to 2.4GHz mode, plug the receiver into your computer, and install the two AA batteries included for it to work. Additionally, it features an auto-sleep mode that kicks in when the mouse is not in use, helping conserve battery life.

Frequently Asked Questions:

How do you use the Kensington Expert Trackball?

You might feel intimidated seeing the Kensington Expert and worry about using it but fear not, for this mouse is pretty user-friendly. Thanks to its ambidextrous design, the Expert can be used with either your right hand or left hand.

If you’re a new trackball user, it’s important to ensure that your hand sits in the right place on the wrist rest and your fingers in the correct position. With the Expert, the one position that you can do is to roll the ball using three fingers while your thumb and pinky rest on the two lower buttons.

Another way is to use it is to “claw grip” the top end of the ball and occasionally rest your index finger and ring finger on the two top buttons. Your ring finger can also be used to spin the scroll ring while your index and middle finger can control the ball.

What is the difference between a scroll ring and a scroll wheel?

A scroll wheel is a vertically-oriented wheel that can be found between the left and right buttons of a standard mouse. A scroll ring encircles a trackball. It operates similarly to a scroll wheel, allowing you to rotate it with your thumb or fourth finger while still in contact with the ball. With the scroll ring, you can move your cursor and scroll up and down simultaneously.

Are there alternatives to the Kensington Expert?

If the Expert isn’t available to you, fret not for there are other trackballs that you can look into. One of them is the Expert’s sibling, the Kensington Orbit. The Expert is a poor choice when it comes to portability; on the other hand, the Orbit has a smaller stature, allowing you to bring it wherever you want. It also features a ridged, rubber scroll ring around the ball. 

Another one that you can consider is the Logitech MX ERGO. Part of the MX lineup, this mouse has its ball located on the side, making it ideal for those used to a palm grip. You can also look into the Logitech Ergo M575 that has a right-handed design and is well-suited for a palm grip or claw grip. Compared to the Expert, the Ergo M575 uses only one AA battery. Both the MX ERGO and Ergo M575 are compatible with the Logitech Options software for you to customize the mouse buttons.
