Logitech Trackball Mouse Original

I am so grateful to have found the Kensington Trackball. I bought it to replace two Logitech trackballs that I had previously owned (the M570 and the Ergo M575). I had to go online to find the Kensington because all of our local stores only carry Logitech. The Kensington is brilliant. Once you learn how to customize the trackball using Kensington's software, it's easy to find the most comfortable angle for your wrist. The Kensington is solid and heavy, which I like. It stays in place on your desktop. The USB dongle connects the mouse without disruption. And I like the scroll wheel. The Kensington itself is more intuitive to use than you would think, and (hopefully) it will last a long time. It comes with a manufacturer 3-year warranty, which is the longest manufacturer warranty that I have seen on trackball mice of any brand. This mouse is definitely worth the price. I take online classes and write computer programs, so this trackball mouse helps a lot with relieving wrist and forearm pain. It's worth the investment. It takes a few days to get used to it, but once you do, it's doubtful that you will go back to other mice, trackpads, and such.

I've always used a trackball over a mouse. No need for extensive desk real estate. This is my second Orbit, one on home desktop and one on work desktop, both of which replaced Logitech Trackman trackballs. The Logitech was good but no scroll ring. I also have two Kensington Expert Mouse trackballs on editing machines. These are the best but a little pricey. The Kensington Trackball Works software also makes it easy to customize your user preferences and responsiveness.

I've been using Kensington trackballs for about 16 years. I forget what they called the with one with the wheels but that was my first. I moved to expert mouse when optical technology came out. I still use an Expert Mouse wireless, an Expert Mouse, and now this SlimBlade. Believe me folks NOBODY makes a trackball as smooth as Kensington. I got this SlimBlade to use with my HP laptop because I just couldn't stand the products offered by Microsoft and Logitech. The SlimBlade has a unique way of scrolling by twisting the ball and after two weeks I see the death of the scroll wheel on the horizon - it's that intuitive. If you want a trackball save the money you'll waste on a MS or Logitech ball and pay the few dollars more for the Kensington. You won't go back.

I have owned Logitech trackball mouses since 2000. Most I loved, a few I used but recognized some issues. In general, I consider a thumb based trackball mouse to be the best out there. It uses a thumb which can rotate in any direction and is built for fine motor skills unlike the wrist driven mice. Here's why I like this particular mouse and call it the best I've ever had: 1. Everything is well built and works without issues. The ball itself swivels easily. It's easy to clean. The buttons work. It sticks to the desk and doesn't move 2. Bluetooth is a dream. It connects easily to my Mac and stays connected. It's just rock solid in that way. 3. Battery life is long. I have usually forgotten the last time I replaced the battery by the time I swap in a new pair. I was a bit worried because I wanted to use bluetooth and Logitech warns that bluetooth connections consume more battery than their proprietary connector 4. It's easy to use Mac config to set tracking speed, scrolling speed, and double click speed. Overall, this is the best mouse I've owned.

I tried several mice and trackballs including logitech M570 and the Trackball Marble. This trackball by far is the best for CAD. The ball movement is so precise, fast and smooth. The stroll ring could be better, but it's not so essential to my work. Highly recommended.

This is a very nice mouse, better than the original Logitech MX Master that I use, in terms of button click noise and smoothness.

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.
