Four DPI settings let you easily adjust the cursor speed to fit your needs by selecting the appropriate level (400, 800, 1,200, or 1,600) — lower DPI for precision editing, and higher DPI for word processing or casual browsing.

Compare size of the Kensington Orbit with Scroll Ring (grey and white version (top), Kensington Pro Ergo (left), Kensington Orbit Fusion (middle) and the Kensington Expert Wireless (right). The speed of the scrolling can be set in the latest Kensington Works software. Be sure to update your KensingtonWorks if you have an older version installed, so that the Orbit Fusion shows up. ButtonsThere are also some companion app issues, though these could also be exclusive to Windows 11, which I've tested it with. There are settings for DPI and scroll speed in the app, as well as to enable and disable acceleration. Only they do nothing. You have to use Windows' built-in mouse tools to make any fine changes. New to the Orbit Wireless over the regular Orbit is an integrated DPI switch (four stages from 400-1600 DPI) on the bottom, right next to the switch to go between 2.4GHz wireless and Bluetooth. You also find the battery door underneath because the Orbit Wireless takes regular old AA batteries. I don't mind this, though some might because as a parent I have an endless supply of AAs ready to pop in at short notice. But you're not likely to be swapping them very often, anyway. Insert the AA battery in the Fusion Orbit, insert the USB 2.4GHz nano receiver in your computer, with or without the USB-A adapter, and turn on the Fusion Orbit with the button at the bottom. Holding the Orbit Fusion, it feels nice and solid. Nothing too spectacular, but it’s well made, nice matte plastic, with some sharper edges and smooth palm shape. The unique finger-operated scroll ring provides a more precise, intuitive and comfortable scrolling experience

A detachable wrist rest delivers soft cushioning to support the hand and wrist in ergonomic comfort for pain-free productivity during extended periods of activity on the computer. The Kensington Orbit Fusion (left) is a direct competitor for the Elecom DEFT PRO (right), but its scroll ring sets it apart.I prefer the bigger devices as I have large hands. I can work with this Orbit Fusion quite well, although I do find it easier to move the ball with the middle of my fingers, not my finger tips. However, they tend to be suited for right-handed users. Left-handed ones are available, but they can be harder to find! All-day comfort is provided through a sculpted mouse-like design to improve palm, wrist, forearm and shoulder position with less hand movement. While the mouse is fantastic for gaming, it has limited compatibility. You will need Windows 7, 8.1, RT8.1, and ten or later. It is worth noting that the horizontal scrolling function will not work with Windows RT8.1.In terms of Mac, OS 10.13 or later will be required for the mouse to work. While this is not as much compatibility as other mice on the list, there is still a good range that most gamers will be using. That alone is enough to make it worth buying because, like its wired sibling, it's extremely comfortable to use, good value and the scroll ring is a thing of genius.

The ring is quite big and high, and on an angle. I’m a big fan of a scroll ring compared to the small scroll wheels, so I’m very happy with this feature and it doesn’t disappoint. It feels smooth and is very easy to move with the ring finger. The unique finger-operated scroll ring provides a more precise, intuitive and comfortable scrolling experience. It just sort of sits there, it comes away far too easily, and it'll move about more than you'd want a wrist rest to. It's a shame because it is comfortable, but it's just so frustrating to actually try to live with. The first time I bought a replacement, but when it happened again, I called Kensington to ask about this problem and alert them to the fact that there was a problem. They denied that there was a problem and told me point blank that I was the first and only one to have complained.

Why Convert to a Trackball Mouse?

The only thing I really don't like about the Orbit Wireless is the same thing I don't like on the regular Orbit. The included wrist rest is a nice touch and it's useful, but it's also not very good. Personally, I prefer not using it anyway, as the position of my hand feels better, but the point is more that it's just not very good. It sort of clips to the lower portion of the Orbit Wireless except it doesn't really. ELECOM’s mouse uses a DPI cursor to ensure high-performance gaming can be delivered to you. The DPI button allows you to change between 500, 1000, and 15000 DPI adjusting the speed of your movements when you need it most! Great for those who play a wide range of games.

All-day comfort is provided through a sculpted mouse-like design to improve palm, wrist, forearm and shoulder position with less hand movement Another factor to consider is the connection of your mouse. These days, most mice on the market will have a wireless option. Using a USB port or Bluetooth connection, you won’t need to worry about wires getting tangled or clogging up your desk. The size of the ball is 40mm, a good, medium sized ball. I’m happy it’s not smaller. For me, it could even have been a bit bigger like the 44mm Elecom DEFT PRO ball, but it’s not a dealbreaker.Compare the ball size of the Kensington Pro Fit Ergo (left), Kensington Orbit Fusion (middle) and the Kensington Expert Wireless (right) Kensington is in denial, they have been for 15 years at least. I wish it were otherwise– I like their products…I just don’t trust them. You have the choice between a wired and wireless mouse with the Kensignton Expert. You can connect your mouse with Bluetooth to save a USB port or use the nano receiver for fantastic connectivity. If you have large hands, and are willing to spend a more, I would look at the Kensington Expert / Kensington Expert Wireless (a classic), or the CST (my current personal favorite, but expensive and not many buttons).
