This product is pure joy..........................

I have only used the Kensington Expert Mouse Trackball& continue to love this product!

This mouse may be large on the desktop, but once used to it, it is just what I needed.

I'm straining not to be too critical because I haven't really begun to use the trackball. I finally had to give up trying to install the trackball onto an HP with a wireless mouse and keyboard combination and summoned the Geek Squad to my apartment. He got everything up and running in about 15 minutes. I couldn't get help from Kensington and I still haven't found a user guide that explains a very complex device.

I could not get the Bluetooth to work. The USB connection works with no problem. The mouse itself is huge . My fingers get numb in no time because of the uncomfortable wrist angle.

Great product!!! Works well easy setup and no issues.

The Kensington - Expert Mouse® Wireless Trackball - Black is great!

Trackball mouse easy to install and it works great.

Overall this roller mouse worked. It has a big red ball and it was also shiny. I didn't like it so much so I returned mine but I bet somebody out there would like it.

Terrible, uncomfortable and the trackball does not accurate track

Did not work good with my laptop and it was way too big!

I tried a large variety of mice and trackballs over the years to deal with repetitive motion strain and the the Kensington Expert remains among my favorite. The ball allows for effortless control of your PC, it's great for internet navigation and game play. The wrist rest tends to come detached much too easily, it's not worth the hassle using, Kensington needs to work on this part.

Man if I knew transitioning from Apple Mouse to Trackball Mouse was this easy, I would have brought 2. The time of purchase (2) weeks ago, I paid $85 & purchased a Logitech Mouse the same day. Got use to the Logitech quick fast, and then opened this one here, comparing Hyundai to a Mercedes!! Now the price has increased to it’s regular price, for what I paid I should have brought two!!!

I am 87 and the track ball is very cumbersome to use

The scroll function on this trackball never worked on my MAC, so a year later, I buy another and the same issue occurred. Kensington will not replace unless I have the original invoice, but they asked that I sent the old one back. Crap Company!
