Summary: It's still my favorite track ball design. I've gotten used to the scrolling feature which is now accomplished by turning the trackball like a water faucet. I had the previous version of this track ball that had the scroll ring. So this took a couple of days to get used to it. My biggest disappointment is the software. MouseWorks did so much more.
Driver software is a serious issue; otherwise quite good if you have the desk space.

Summary: Like most people in the trackball market, I switched from ordinary mice for ergonomic reasons. From the three trackballs I own (Logitech right-handed thumb-ball, Kensington Orbit with Scroll ring and this), this may just have the best record in that respect, followed closely by the Logitech. (Unfortunately, I'm left handed, and there's a limit to how long I can use a right-handed device comfortably).
Great (GREAT!) hardware compared to Expert Mouse, but the programmable button issue is like BMW dropping cruise control...

Summary: UPDATE 10/21/09: Slimblade Buttons Programmable in Snow Leopard via USB Overdrive 3.0.1! As mentioned in my review below, I had tried earlier versions of USB Overdrive as a means of programming the Slimblade under Mac OS X without success. However, Alessandro has updated USB Overdrive and it now supports programming the Slimblade buttons (and is compatible with Mac OS 10.6).
Summary: Hi, I am an "expert" user. I have been using Kensington trackballs since the early 90s and must admit that I never truly got over the tragic passing of my Turbo Mouse Pro. In my opinion the standard by which all trackballs ought be measured. Eight completely customizable function buttons in addition to the standard right & left click plus a very convenient wee tiny scroll wheel in the perfect position just above the uber comfy ball.
Summary: PROS: This is a BEAUTIFUL mouse, I've had issues with past larger Kensington trackballs because of their steep rake, this one fits in the hand fantastically. The scrolling action is ok (done by twisting the ball), sometimes I accidentally trigger it when mousing around. CONS: The software ruin's this wonderful hardware. ZERO customizability.
Summary: Als je flink spasties bent is het een hele uitdaging om je computer zo aan te passen dat je er makkelijk gebruik van kan maken. Er zijn speciale aangepaste muizen op de markt. Maar die zien er meestal niet uit en zijn erg duur. Deze trackballmuis heeft een grote makkelijk beweegbare bal en grote knoppen. Daarom een serieuse kandidaat als je bewegingen niet al te gecoordineert zijn.
Pros: formaat, stijl, stevigheid, gewicht
Cons: onduidelijkheid hoe alle mogelijkheden te benuttiggen zijn., De bal kan er uit vallen
