The Kensington Expert Mouse Trackball is like no ordinary mouse . I got this mouse as a gift. However, I did a Google search and this mouse costs $119.99. I, personally, feel that this mouse is over priced. I had expected this to be roughly 60 dollars. This mouse is nowhere near what I had expected.

I have several of the Kensington Expert Mouses. Everytime I use a a regular mouse, it reminds me of how much I love the Expert mouse. you never have to pick up and reposition a traditional mouse when you cant get to the edge of a page.

This is excellent for people w/ carpal tunnel or other "grip" problems. The grooved circle around the ball is great for scrolling. Regular mice strain my thumb & wrist. But if you need a mouse for gaming, this is not it. The gamers in my house hate it.

Love this mouse. I have been searching for an ambidextrous wireless trackball for a while and was hesitant to spend the money on the Kensington Expert Wireless trackball. There should have never been any fear. The button placement is perfect and the trackball glides effortlessly.

I use this without the wrist rest, it's a very comfortable mouse to use. The scroll wheel is a great feature. The software was easy to install on to my mac so you can then add functions to the extra two buttons, such as copy and paste.

great product! other then the the scroll ring stopping clicking this holds up and is easy too clean and just as accurate as the day I bought it.

I love this trackball. It is very comfortable to use. It is much faster using a trackball than it is a mouse. It is more precise than a mouse. So if you are using CAD or photo software this is the best type of pointing device. I highly recommend this trackball.

Moving forward, for personal usage on a gaming rig, I would look elsewhere. As a device for productivity, I don't think it can be beat if you have the option to use Trackballworks (I would so buy one for usage at a job with an assigned station, your coworkers have less of a tendency to get grabby!).

Excellent accuracy; and granular control of functionality within the driver software (Trackballworks)

Trackballworks; Functionality is mostly tied to the driver software, as the extra buttons aren't recognized properly within Windows 10 or Linux Mint without it (no experience with this mouse in prior versions of Windows); The driver software impairs compatibility with a lot of the games I tried.

I was so excited to see this trackball not only that it is wireless but also a new look, the red ball and black Matt color that it seems like something out of Star Trek, LOL. The Spinningwheel is not as smooth as my previous wired truck balls but I think that will just come with time and usage...

After ordering this item along with a motherboard from this site i was so surprised to see it sitting on my doorstep the next morning, also exited because they were the last pieces of my most recent build. The packaging for the mouse was decent if not better than most.

I however had sent it back for one reason though, it felt really cheap; even though the ball itself had some weight, the rest of it felt so incredibility cheap under my hand; the scroll wheel and the buttons were made out of really light and thin plastic and it felt as though i would certainly break...
