It loses one star for two reasons. First, the price. Paying over $100 for a pointing device is hard to justify, especially when the Kensington Expert Mouse Optical USB Trackball for PC or Mac 64325 is $67, and the Logitech Trackman Wheel Optical (Silver) is just $26. Second, the build quality isn't perfect. I have three of these units, and on all of them, one of the ball rollers has a sticky point (you can feel the ball get a little "stuck" briefly). On two of the three, the scroll wheel gets loose in its housing.
But these are small details for what is otherwise an excellent trackball.
Things about this trackball that are better than the SlimBlade Trackball: Everything.
1. This trackball mouse fits my hands better. 'Case you know what they say about one with large hands? E needs a large trackball.
2. ALL buttons are recognized as expected without having to modify the input pipeline. (Seriously, Kensington was insane to make 3rd and 4th buttons non-standard on the SlimBlade)
3. The trackball tracking sensors do not require constant cleaning. The SlimBlade constantly required cleaning the stupid holes the optical sensors where in.
The only issues I have are:
1. The scroll wheel could do with a bit of resistance. I find it's a bit *too* easy to move.
2. The button combination middle + right is used to change the tracking resolution. I actually use this combination. This causes problems.
After using it for a week:
- The scroll wheel is awesome! Hard to reach, but really, really good.
- The ball has more resistance than I have had with Logitech balls.
- The ball moved well vertically and horizontally, but grinded down on moving diagonally.
- It had a middle mouse button, which was configurable.
- But no dedicated back/forward buttons, which is a loss.
- It's amazingly heavy. Most of the weight is the billiards-sized ball.
- It's corded, which isn't a big deal, but just makes it look "dated".
- DPI switching is a nice idea, but it fails in execution as I have reassigned the middle button to minimize
I would like to like this model. The price tag gives the impression it is something special, but in reality it feels to me like it is a "government" pointing device that is meant to stay in an office until the end of time. As such, it hasn't kept up with the times with mouse functionalities that are considered standard.
The design forces the wrist far below the hand: about the worst position to put the user in. The scroll wheel is positioned so reaching for it either results in a miss (hitting and depressing the third button) or inadvertent rolling of the ball. Large hands will reach the scroll wheel without arm movement, though still hitting the trackball. Users with small hands must lift their whole arm and move it forward to utilize the scroller.
The slab of plastic the heel of a user's hand must rest on absorbs heat quickly but does not conduct it away from the hand; half an hour of use and it feels like there's chemical heat pack in the case. To add injury to insult, the surface becomes slippery and dries slowly when the hand inevitably sweats in response to the heat characteristics of the plastic.
In short, not a terrible device to have on the shop floor for occasional use, though too expensive for an area where it's likely to be damaged frequently or used by dirty hands. Poorly suited for long or precision use, e.g., CAD, gaming. People with a proclivity for wrist or forearm injuries should avoid this like the plague.

I love how it scrolls and how fast it is when you are using the cursor. I just wish they could have made it smaller so that it has a natural feel when your using it. Read morePublished on August 8, 2013 by tadd
