Summary: The ultimate trackball
Comment: I have owned one now for 6 months, and I can say without a doubt that this is the ultimate trackball and maybe the ultimate hand-input device for a computer besides the keyboard. If they were a little less expensive I would buy a few more for work and other computers I have, but if the one I had broke, I would replace it in a second. If you are an experienced computer user and you want a great trackball or mouse alternative, this gets my vote for the best option if money is no object. Anything cheaper will have some drawback or another, this doesn't have any drawbacks other than the higher initial price.

Summary: Smooth action
Comment: As always, this Kensington trackball is smooth as can be. My only negative comment is that they have gotten rid of their direct launch buttons. I switched to trackballs years ago to help with the ergonomics of my set up and having those buttons was a huge help.
Great functionality here.

Summary: Best of All Trackballs!
Comment: I purchased this as a gift for my husband. The box, when it arrived, was surprisingly heavy. We opened it up and found that the thing is HUGE. The ball is about the size and weight of a pool ball. It has an optical movement, so perhaps it won't be plagued with the problems that he had with the Kensington TurboBall(for no discernible reason, the TurboBall, no matter how often he cleaned it, would periodically glitch out where the cursor would only go in straight lines- horizontal or vertical- and it drove him nuts, eventually back to a regular rodent). This trackball, he says, is great. He is enjoying it a lot, and the huge ball is very comfortable to use, as is the scroll wheel. An added bonus is that the buttons are programmable, so he can truly make it work HIS way. Good news indeed- I know that I will have something to go to when my beloved Microsoft Trackball Explorer (no longer manufactured) bites the dust!

Summary: Indispensable trackball
Comment: After using this trackball, it is absolutely frustrating to be without it! I even carry it along with my laptop!
No more running out of space on your mousepad in the middle of an operation and having to start over.

Summary: Great improvements on a great product
Comment: I have been using different Kensington Expert mouse products for almost a decade, and have gone through quite a few of them. This new optical version is great because you don't have to take out the ball and clean the rollers anymore, and the ring-scroll wheel is awesome.
