Kensington Ergonomic Expert Mouse

[Mac, Windows] 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.

[Scroll Wheel] I have been using Kensington's Expert Mouse since 1999 and I just do not know why so many others have not made the change. It just simplifies my work flow. I do have issues every so often with scrolling only because after years of use things do wear. Kensington is pretty good with their warranty but this time I had to purchase a replacement because my mouse was in use 7 years.

[3.25 lb] The best - in my opinion - is the Kensington Expert Mouse which has better precision and control. This one is better for travel since the ball does not fall out and it is more compact. Both provide additional buttons which can be customized to improve the workflow.

[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!

[0.41 lb] I have been using Kensington Expert Mouse trackballs for over 20 years, of course mostly the wired versions which are still in use in my studio. I added a couple of wireless versions, and I don't think I will be buying wired ones ever again. The best thing is these devices keep working year after year, update after update. Amazing!

[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.

[2] This is not my first Kensington track roller - I LOVE them. Great ergonomic set-up. takes a little getting used to, but then so good for your mousing hand. The newest version throws me off a bit as it puts itself into deep sleep so each morning I have to remember to flip it over and turn it on again, but that is better for battery life.

[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.

[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.

[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.
