6D Ergonomic Mouse Scroll Button

This mouse is a must have for anyone working with a 3D program that requires a middle mouse button. At first glance the mouse looks like any other mouse with a scroll wheel. Look closer. Between the left and right button is a real middle mouse button needed for navigating 3D space in most programs. Using a clickable scroll wheel instead of a real mouse button just doesn't work for me. The activation force required for clicking a scroll wheel is cramp inducing and it's too easy to accidentally scroll (zoom) at the same time. The CadMouse solves this problem with the extra button. I have a 3Dconnexion Space Mouse as well, so I don't know how I missed this gem. It's perfect for 3D on its own or as a Space Mouse companion. Thanks 3Dconnxion!

Compared to the mouse, this trackball takes some getting used to, though I'm finding the scroll ring, ball and left button intuitive, and will learn to use the right button with time. I am glad that I also ordered the mouse pad with gel wrist rest; much more comfortable than the extended tailpiece.

[This review was collected as part of a promotion.] A good basic wired mouse. 2-button with a scroll wheel in the ThinkPad color scheme.

I love how the mouse is totally silent, and it is super comfortable to use. I really like how you have that extra button on the scroll wheel, and you can customize that in the app, it helps with productivity. 5 stars

Home use. Great ergonomic mouse!

This is a very comfortable and ergonomic mouse pad.

As the headline says. I like the scroll wheel too. I use it at a workstation w/o room for a mouse.

In a touch screen digital world, switching from Logitech MX Master mouse to Kensington Expert felt like going Back to the Future. I gave myself 7 days to work only on Kensington Expert Mouse. The tactile feedback of a large ball turned out to be extremely satisfying experience. The feature I've used the most on MX Mater, and I thought I would not have on Expert Mouse was a thumb-wheel function, which was setup to switch between the 3 virtual desktop screens I have on my Mac. Quickly I've discovered that the top buttons on the Expert Mouse are perfect replacement for my MX master thumb-wheel. I've also programmed top buttons to run Expose when pressed simultaneously - the feature I used on MX Mater with a thumb button. Now the biggest issue was a middle mouse click.. but it turned out to be as simple as programming two bottom buttons acting as the one, when pressed both at the same time. The big bonus is that if one needs to use buttons to perform different actions, one can do so. Kensington software allows per application button customization. I would consider all mentioned above as pros for this product.. now few if any cons - the scroll ring needs a redesign. At first I thought that I may have a faulty item, but watching couple of videos on the internet, I've found out that that gritty feeling is due to the ring design implementation. It's true.. the grittiness fades with use, but it's still far cry from a silk-smooth operation of MX Master scroll wheels. Minor cons is a somewhat high profile of the Expert Mouse. I have a large hand, so this is no issue for me at all. I'm looking forward to get the Kensington SlimBlade, which in my mind would eliminate high profile and gritty scroll ring. Overall.. if your desk keyboard/mouse space is limited, or you want to discover what you were missing all these years, using regular mouse - trackballs are way to go. Especially if you have a full size keyboard. Excellent product - highly recommended.

Not one, or two or three, but Four programable buttons this Mighty Mouse can do things no ordinary mouse can do! Great scroll Wheel also programable,

Mouse is one of the modern instruments most of us use most during the day, and incredibly enough not much thought in terms of ergonomic design is given by manufacturers. This mouse is excellent. I used to have minor pains after prolonged usage, until I found this mouse.. Hope more manufactures start giving more serious thoughts to mouses. I know the price is high, but how much is a healthy right hand / arm worth?
