Best Vertical Trackball Mouse

[Optical] Best vertical mouse ever.

[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!

[White] 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.

[200 to 12,000] Best mouse to date

[Ball] [This review was collected as part of a promotion.] I have used a trackball mouse for years, this is my first wireless trackball and I love it.

[This review was collected as part of a promotion.] The HP 920 Ergonomic Wireless Vertical Mouse is a great alternative to the normal computer mouse. Although I have had no issues using a regular mouse, I was excited to try the vertical design. The HP 920 mouse is considerably larger, more meant to fit the curve of the right hand and thumb. It feels comfortable in the natural hand position. The bottom attachment adds to the bulk but provides a resting spot for the bottom of the hand and wrist. The included usb dongle works flawlessly and has a dedicated storage compartment on the mouse. I find it easy to move the cursor, scroll, right click, and left click.

[Ambidextrous] I was getting a bit of carpal tunnel from my mouse in my right hand. Got this trackball and set it up to use with my left hand. I now switch back and fourth between this and my mouse. Still training coordination but so far it's helping a lot.

[Ambidextrous] 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.

[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.
