So you're an Epinions junkie, but you've been diagnosed with carpal tunnel? Other than relying on a trained monkey (if you can afford to get one trained to use computer equipment), you will probably have to go in for a major computer workstation/set-up...

Pros: Big, smooth rolling ball. 4 big, easy to hit buttons. Excellent acceleration software.
Cons: Doesn't use USB. Buggy drivers

Kensignton made a big name for itself many years ago with its original Turbo Mouse and Expert Mouse designs. The two mice were legendary for their solid feel and was a must-have for professionals. The latest revision, the Expert Mouse 5.0 and Turbo Mouse...

Pros: Durable, programmable, best designed non-optical trackball around.
Cons: Takes up desk space; pricey (but worth it).

Please understand to start with that I've never liked mice and have always preferred a trackball to chasing a mouse around. As a result, over the past 16 years, I've tried many different trackballs; none have equaled the Kensington Expert Mouse series...

Pros: Precision and features are the best around for maximum efficiency
Cons: Button placement could be better

This is a review of a newer model: Kensington Expert Mouse Pro Model 64213.

This trackball style mouse has everything that the one pictured above has, plus the application/web site launch buttons.

Who buys a track...

Pros: large solid trackball, large easy to click buttons. Awesome 5 year warranty
Cons: serial cable with ps/2 adapter (should be a ps/2 cable with serial adapter)

The Kensington Expert Mouse track ball is an excellent product. I've been using mine for 4 years now. One thing I am very impressed with is the 5 year warranty. For some reason, probably my overuse of the product, the "mouse" stopped working...

Pros: Many Options
Cons: none

I have had my expert mouse for almost a year and I have been very pleased with it.
You can set it up to double-click, drag, print a document, save a file, enter text, with just one click!

Pros: Ergonomically Ideal
Cons: Expensive

The Kensington Expert Mouse is expensive, but if you need something that isn't going to hurt your wrist, you have come to the right place. This is a premium input device.

The Kensington MouseWorks software allows you to configure the button...

Pros: Increases productivity, very durable
Cons: More expensive than other input devices

I purchased the Expert Mouse 5.0 (the version number makes a difference) in 1996. My Expert has DB-9 serial and PS/2 interfaces via a six-foot cable. The trackball is the size of a billiard ball, and sits in the middle of four buttons, two large...

Pros: Ball Size, Button Location, Ease Of Use, Versatility
Cons: No Built In Wrist Rest

http://www.kensington.com/products/pro_mic_d1324.html Having been a fan of trackballs for years, I attended this years Comdex in Las Vegas not expecting there to be very much new in the field. I was pleasantly surprised to find out that not only was...

Pros: Excellent quality construction, buttons are easy and comfortable
Cons: None

I've been using this trackball for nearly 3 years, on both Macs and PCs. I've used other trackballs, including older generations of this device, plus the Kensington Orbit, which I don't like at all. As someone who has suffered from carpal tunnel, the...

Pros: Smooth action, Comfortable
Cons: $$$$$$

Of all the mice and trackball products I have used (A lot by the way) Kensington Expert mouse trackball is just the best. The smooth glide of the ball far exceeds any I have used. It's sturdy, dependable and easy to configure. If you are a back button...

Pros: Great for lefties and righties alike
Cons: Takes awhile to get used to

The Kensington Expert Mouse trackball is a wonderful alternative to your standard computer mouse. It's easier on your wrist, since you don't have to move the whole piece of hardware around to navigate your computer screen. My arm used to get achy...

Pros: fantastic hardware design
Cons: Software needs to be better written to handle USB

Kensington has pretty much owned the trackball market since the introduction of the Expert/Turbo Mouse. It's a solid piece of hardware. However, as computers move into the age of USB, the software has lagged behind. If you use PS/2 or ADB as your primary...

Pros: Easy to use, more ergonomically appropriate, than most mice.
Cons: Gets dusty faster, and needs more cleaning.

I recently received this product for Christmas. I had asked for it because I like a trackball better than a mouse. This mouse is all I could ever ask for. The Kensington expert mouse has four buttons, one in each corner acting as the left and right...

Pros: Easy to use/don't have to worry about a mouse pad/reliability
Cons: Some would say the cost...but I would have to say it is worth it.

The Kensington Expert Mouse, Version 4.0 came into my life 8 years ago as a Christmas present for my husband, a Computer Programmer. Once I begin to use the trackball I understood why he insisted on having one.

Just recently we purchased...
