This review is from: Kensington 4-Button Expert Mouse USB/PS2 Trackball (Personal Computers)

I've used the Expert Mouse, daily, for at least eight years. Computer systems have come and gone, but the Expert Mouse endures. Calling it rugged doesn't begin to do it justice. I originally purchased this unit for computer graphics applications. The very large ball and stable base give the user precise control over cursor movement. And for games...it's speed and responsiveness are unbeatable. My first Expert Mouse developed a problem with the cable socket. Kensington replaced the entire unit, free of charge and no questions asked. The replacement has endured seven solid years of hard usage. The Mouseworks configuration software is a real bonus. Overall, the Expert Mouse is one of the better hardware investments you could possibly make.

This review is from: Kensington 4-Button Expert Mouse USB/PS2 Trackball (Personal Computers)

I was sad to see Kensington isn't offering this model on their website anymore...I was drawn in by one of their new, shiney, Death-Star-Black models, and was sadly dissapointed how "Un-ergonomic" (anti-ergonomic?) it was. So, back to this model, I'm going.

This ugly, clunky white thing has allowed me to surf carpal-stress free for years. I might actually order more than one...

The only issue I have with it, is that it isn't coffee/soda/name-your-beverage spill proof...but I guess that's my own fault.

They should market and sell a cleaning kit with it as well. Sometimes the rollers get a little gunky, if you tend to eat a lot while you surf...quick-evaporating alcohol wet-knaps seem to do the trick.

Regardless of all the problems I've created for myself, this thing is a marvel of modern engineering. Once you get used to it, it's hard to go back. It's definitely allowed me pain free computer usage.

5.0 out of 5 stars THE Best!, March 23, 2005

Once you use this trackball, you will NEVER go back to using mice, ever again!

No more lifting up the mouse, placing it down, then going up with it again to get to the top of the screen, just keep moving the ball and the unit and your hand STAY on your desk, no more lifting!

Do NOT use the software that comes with this for assigning features and such to the buttons, it causes programs and computer to crash all the time. Just install the DRIVER, if needed, but use the mouse adjustements in the CONTROL PANEL of windows for fine tuning, you don't NEED the software that comes with this, and not only do you not NEED it, it will CAUSE problems!

Several recording studios tried to use this great trackball with the Steinberg AUDIO CUBE, and said it did not work. I said hogwash, and installed and used this trackball on an AUDIO CUBE without problem, because I did NOT use the included software!

When I explained this to the other studios, they found they were able to use this trackball just fine without the software too, the software CAUSED the problems that would not let it work with that program or computer.

And the last thing you need is another program running in the background using up your computer's resources! Windows ALREADY HAS software for a mouse included on your computer NOW, so you are already set!

I have used this trackball at work, and have the same one at home, and used them for over 10 years and would never use anything else.

The BALL inside this is the exact size of a Pool (Billiards) Ball, so you can just lift the ball out with your hands, and drop in an 8-ball if you want.

You can draw, and trace out objects in photoshop with this that you can NOT do as well with a mouse.

For Digital Audio Workstations, or Photoshop / Graphics design, you MUST have this trackball, nothing else is acceptable.

The 4 switches are quality MICROSWITCHES that never wear out and give you that perfect tactile feel so you KNOW you are activating the switch. The same type of quality microswitches in arcade video games.

There really is NO trackball or mouse on the planet that even comes close to this one. This one IS THE best.
