Almost a Logitech Marble Trackball....but Not Quite
This is a LARGE trackball, which is perfect for any operation requiring detailed operation (CAD, Painting, etc.) as well as general everyday usage. The 4 triggering buttons are well placed and responsive, the whole housing is quite ergonomically designed for an extraordinarily comfortable fit - regardless if you have small hands and fingers, or large paws like me. The scroll ring is the high point of this trackball, since it is not a mouse, there is no scrolling wheel. Almost all other trackballs have no ability to scroll except to move the ball along the drawbar - and most trackballs' ball is too small to be delicate enough to just move a line at a time. The scroll ring acts just like a scroll wheel on a mouse and is extremely accurate. So why the 4 stars instead of 5? You have to ...

I have never had to clean a Logitech trackman Marble ball, but this Kensington requires constant cleaning to operate smoothly. But, then again, the Logitech model isn't even close to being ass accurate as this Kensington, which is why I purchased the Kensington in the first place. For everyday computing, get the Logitech. For detailed applications, this is the ONLY trackball - get the Kensington!!

Good device with correctible ergonomic issue
I am a trackball fan; I thin they can provide the best general mouse service; most especially, I think a trackball, properly designed, is least likely to cause strain to the wrist and arm. We have a number of ITAC trackballs in service, they are built like the proverbial brick outhouse and they are very good for long sessions at the computer. But I recently had a couple that needed service (after a decade or so of active use...), and I needed a fill-in. The Kensington Expert and Slimblade models were the best options I could find. I opted for the Expert, based on its included wrist rest. It is mechanically simple and appears robust. The scroll ring is convenient and works well — a selling point. However, the hand position when using the unit is a problem. The angle of the unit ...

However, the hand position when using the unit is a problem. The angle of the unit means the wrist is flexed upward when twiddling the ball. This is a stressed position. The quick work around has been to use a foam "eraser" sponge on top of the wrist rest. Pictures suggest the SlimBlade trackball may have the same problem, but more readily corrected.

great large stationary mouse!
Excellent mouse for those with muscle cramping issues and carple tunnel and vision problems. I have vision problems and this mouse replaced a similar serial version from the 80s with no scroll ring which was anoying. I love the flexability and features this mouse has for what I payed for it preowned. I only wish they redesigned it with a standard scroll wheel and placed it between the two top buttons instead. I tend to bump it from time to time and it can be a little distracting. If there was a way to disable it in sofware and assign top left, top right to scroll up and down respectively that would be good enough for me for now, I am sure there is a way. Besides the little wheel issue there is nothing really to complain about I absolutely love this thing and super happy to have found it ...

I use fl studio, drawing softwares, audio editing and other presision tools and this is a great mouse for playing old arcade emulators too.

Great mouse for beginners or experts
Solid mouse. Trackball feels natural in your hand and makes workflow much easier. Really useful for my setup at home. While it’s a bit noisy it is still very much worth it. Especially if you find a deal on these models. Next best thing to this one would easily be the wireless or thinner version of the expert trackball mouse.

Used by professionals of many types of business and software
I went to a power plant several years ago as a visitor and the control room had 8 large monitors with 8 of these trackballs in front of all of them. I tried one and now I have 1 of these in front of both of my systems with large monitors. Oh yeah, 1 at work also. Never looked back. 4 buttons will do 6 functions of your choice. The wired version is very precise.
