Kensington Arm Rest Trackball

[1000 to 2400] For many years I have used the corded version of Kensington Trackball. Now is the time to make the switch to Wireless!

[2x AAA] I've been using the Kensington trackball for a couple of weeks. It worked out of the box on my Linux machine and it's been responsive and reliable. The ball doesn't seem to clog quickly, and the button on the bottom to push it out for cleaning is a great idea. It works on Bluetooth as well as with their wifi dongle, which caused me some trouble when I switched it to Bluetooth mode by mistake, but when I finally read the instructions I quickly changed it back. It has buttons all over the place. I don't know how to program them under Linux nor would I want to, but fortunately they seem to do nothing if unprogrammed, as it's hard to use the trackball without clicking them now and then. This hasn't interfered with my use of the trackball, though. It feels much like the old Logitech Marble Trackball with a handmade tilted stand that I've used for years.

[Windows] The only better pointing device - in my opinion - is the Kensington Expert Wireless Trackball. This one is a bit less easy to control since it uses the thumb rather than the fingers, but it is great for portability. I especially like that the ball won't fall out and that it can switch between two blue-tooth and one other wireless device.

[USB-A ] 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.

[12] I've been using Kensington trackballs for many years. This is a very ergonomic and sexy-looking one. Also, Kensington has updated their Trackball Works software so it's flawless and quick on Apple's latest Yosemite OS X 10.10.1. B&H Photo offered the best net price.

[1.405 lb] I have been a Kensington Expert Mouse Trackball customer for decades, but up to now have only used the wired version. I wanted the wireless version for when I'm away from home. I use it with a 16 MacBook Pro and prefer something besides the built-in trackpad for moving the cursor around and scrolling chores. When I'm at home, I have the MBP plugged into a dock that has a Kensington Wired Expert Mouse connected. I'm very happy with the wireless version. Works as well for me as the wired ones at home. I use the Bluetooth connection option, not the dongle. No issues to report. Yes, the trackball is somewhat bulky, but there's plenty of room for it in my backpack. I'd recommend it!

[2] Love this product! Kensington's Trackball with scroll ring is the BEST. It helped heal my carpal tunnel due to the natural relaxed hand postion, and it's fantastic for the precise work I do. Toss the mouse and upgrade to a comfortable, efficient, smooth-gliding Trackball. (NOTE: unlike a mouse, there is 1 bit of maintenance to keep it going through it's full warranty period - to wipe the sensors clean where the ball sits. Super easy, to do, but FYI for Trackball newbies.) Cheers!

[1000 to 2400] 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.

[Scroll Wheel] This is by far the best trackball every introduced to the computer world. Nothing compares. Kensington has been making them for a very long time and haven't had to change a thing. It's a smaller footprint and much quicker to get around. LOVE IT. I keep spares in case one dies or Kensington stops making them.

[Scroll Wheel] Kensington has been making excellent mice and trackballs for decades. The trackball is highly customizable and helps me zoom along effortlessly on my 24 iMac. It has four programmable clickers and a scroll wheel that sits at the base of the trackball. Scrolling is effortless and the degree of control offered by this track ball is awe inspiring. Mice run out of real estate and your always repositioning. Track balls don't move, they stay in one place where you can control all the action. Works especially great on dual monitors and large screens.
