Large Trackball Mouse

I have arthritis in my thumb & this trackball/mouse is fantastic.The large ball & the scroll wheel is very accommodating & easy to use.The wrist pad that is included is comfortable & attaches to the mouse so there is no slipping away.

The Kensington Trackball really hits the spot for me. CAD is my primary use... It is large diameter and cruises across the screen. I got a red one. Green or blue would be my choice (that I did not make.) The four assignable buttons and the scroll loop are added benefits.Track balls were the first mouse products long before mouse options became available (using a rolling ball to surface desk, etc. they got dirty) One thing I might like is a travel security as the ball is not secure in its pocket. It is so nice to have the large orb, I take it home and to work and use it on various computers, and laptop. I need to take the dongle with me, but let me say it is nice. It stays in place and does not need all the space a mouse consumes. The wrist rest is a sweet accommodation, but is not required (it was delivered with the trackball. One reason I spent the extra funds for this deluxe product is it can be operated with either hand, hence when I first used a mouse 35 years ago I trained myself to use my less dexterous left hand for the simple point and click two button, and my right hand for the 100+ keyboard. I've had other track ball devices and they were never as easy to use as this honky-dory device. Ron P.

I have been using a trackball for more at least fifteen years (my preference). The 4-button USB Expert Pro Mouse - Trackball by Kensington is there best trackball yet.

I'm at the computer 12 hours/day and I find a trackball much better than a mouse for my hand, wrist, elbow and shoulder. My Logitech Trackball developed floating cursor and I couldn't cure it. I looked at lots of recommendations from friends and relatives, but no one mentioned the Kensington SlimBlade Trackball. I found it on my own, and it is perfect for me. The large ball makes for easy cursor precision. Its simple clean design is very appealing to me. It's the easiest least stressful pointing device I've ever used. (I started out with a CPM machine so some of you will have an idea of how many pointing devices I may have used over the years.)

My 2nd Orbit Trackball. The first lasted MANY MANY years. Made the mistake of buying a cheaper Logitech trackball, that barely lasted ONE year. I really like the big buttons on the Orbit Trackball, & the velocity response (can move cursor both in very small increments, or sweep across the screen quickly). Because I've had a small computer desk (30 wide) for 35yrs, a trackball is necessary. My extended keyboard & trackball fit nicely. A mouse not only requires MUCH more space, I HATE constantly picking up & relocating a mouse to move around the 21 monitor: a waste of time, distracting & frustrating. I never have to look to find where my trackball is! Plug & play simplicity, & easy to clean.

Works great for me. Very good trackball mouse.

Love this wireless trackball Mouse,the ball rolls so smoothly, like silk, this mouse works like a charm We love it thank you

I've used the Kensington Expert Mouse for years now and won't do without it. I recently bought a new iMac with the new Magic Mouse. I did like the scrolling ability of the Magic Mouse but after a week I broke down and bought another Kensington Expert Mouse. It has much more accuracy and stability than the Magic Mouse. Plus, the trackball is easier on my hands and wrist than a traditional mouse. I'm on the computer all day and do everything i can to make my day run smoother. Moving the cursor on the screen is much more intuitive to me with a trackball than with a mouse. The Kensington Expert Mouse does have both horizontal and vertical scrolling. While not as intuitive as the Magic Mouse, it still works.

This trackball mouse works very smoothly and can be customized for your applications and how you work.

Already, somethings I do are easier and more accurate with the pen than mouse or trackball, but still into it's learning curve.
