I got the Slimblade Trackball for my office, to be used alongside a TypeMatrix keyboard and a Func MS-3 mouse. It took a little while to get used to, but what a brilliant tool! Arm movements are no longer necessary, which means less pain in the neck and shoulders.

The base of the SlimBlade Trackball is made of a granite-coloured plastic with four rubber feet on the bottom to prevent it from sliding around on your desktop. Unfortunately, the trackball draws its power and connectivity from USB 2.0.

Comfortable for those physically unable to use a standard mouse; Heads-up display conveniently shows the current mode

Toggling between three modes complicates work flow; Expensive; Lacks Bluetooth; Can't customise buttons or alter trackball sensitivity; Large footprint

Kensington resurrects a dying breed with the SlimBlade Trackball, but the potential of its unique shortcut buttons devolves into a mess of clumsy extra functions and awkward movements that restrict productivity.

There's always been those who'll use a trackball in preference to a mouse or trackpad. Other than aesthetics there's very good reasons for this, not least that employing different controllers is an effective way to reduce risk of Repetitive Stress Injury (RSI) when using your Mac.

Easy to use; extra features beyond other trackballs; nice looking; can help prevent RSI when used in conjunction with other controllers

Action is high for RSI sufferers; accuracy in use doesn't match that of graphics tablets

I love this slim mouse! I'm having problems with my index finger so my employer wanted me to get this mouse to save the 'scroll finger.' I do however miss the scroll wheel from the other Kensington mouse. I find scrolling with the whole ball not as convenient as they make it sound.

Like the Expert Mouse, the Kensington SlimBlade Trackball's based around a static base with a large weighted ball to roll under your fingers, moving the mouse cursor on screen. There are four clickable controls spaced around the Kensington SlimBlade Trackball's metallic grey frame, one in each...

Amazing design... most comfortable mouse I have ever used. Very accurate (although not as much as the expert mouse). Don't like how hard you have to press the buttons at times... not as ideal as expert mouse for gaming (if you like trackballs to game) due to button location.

The Slimblade Trackball is a very nice device. I have been using Kensington Trackballs for years because I like that it sits in one place and your fingers intuitively can move a cursor around the screen without moving your hand like with a typical mouse.

Accurate Tracking; Comfortable Design; Fast Response; Glides Smoothly; Innovative Design; Works On Any Surface

Not Configurable

I've been using the Expert Mouse for years. The newer SlimBlade looked great but i was unsure if it would work under linux. A guy at work had one and i plugged it into my laptop and it worked perfectly. Sold

Very Comfortable; Twist the ball to scroll is great; Low profile

A bit pricey; five stars otherwise(still bought it

Very streamlined and easy to use. I've been waiting for Kensingtin to upgrade their trackball.
