Kensington Mouse Trackball Expert

I use this mouse por general purposes when using a computer. I love the fact that my wrist doesn’t get sore. One of the features that I find great is that after maybe 15 minutes of unused it turns off by itself.

Every time I do not use the cursor for a few minutes, it does not work until I unplug it and plug it in again.

The large-diameter trackball is totally smooth and has given me much better control over cursor position than any mouse I have ever used. I no longer have to be concerned about having to "row" a mouse to make large motions, and my control is always in exactly the same place, which saves desk space. Now if only Kensington would do something about that scratchy scroll ring... UPDATE: Subtracting one star because two days after my return window closed, the two top buttons stopped working. I had them assigned to Cmd-W on the left and Back on the right. Kensington Works shoed the buttons still have the functions I assigned, but they now do nothing.

This tracking ball is for our son who is disabled. He has used a Kensington programmable tracking ball since he was very young and we’ve found nothing better. We know this Bluetooth version will be just as great as his other one. This is a quality product.

This is my third Kensington mouse in only 35 years. That's a good stretch for a mouse. I love em. Why use a large space on my desk for a mouse. Takes a very short wile to get used to and is worth it. And makes it feel better to use an eight ball when its tax time. Its not that much more expensive and and outlasts a standard mouse so much its worth it.
