This is my 5th Orbit, which is both the pro and the con. Very comfortable to use, and has the scroll wheel, which my beloved Logitech Marble Mouse never implemented. However, the first 4 orbits, all wired, ended up going bad within a year of purchase. The buttons started going wonky and not clicking or double clicking, etc. But there's nothing out there quite like it, so this time I went for the wireless one. First off, the wireless functionality is great. Always works, though it needs a little shake after the computer wakes up from a period of non-use. And I just replaced the 2 AA batteries today after 4 months of daily (all day) use. We'll see if it makes it past the 1 year mark with working buttons, but honestly, I'll probably just replace it again if it does.

Works perfect just as pictured and described

I bought this track ball in India. The left click button stopped working in 6 months of use. When I contacted the support, they told that even though warranty is valid, they do not ship replacement outside UK. If they sell outside UK then why not honour warranty in same place?

Ok, I am a certifiable trackball addict who has purchased >5 trackballs over the past 5 years and still use them regularly. For this brand (Kensington) specifically, I can say that it is of higher quality than Logitech and Elecom. My Logitech MX Ergo's "soft-touch" surface has started wearing out giving it a disgusting mouldy appearance; meanwhile, the newer Logitech M575 didn't even last a year and now the scroll-wheel is broken. I also bought an Elecom Deft Pro and EX-G Pro, both of which don't work anymore, not sure why. I put in fresh batteries but the ball simply doesn't track.By contrast, I bought this Orbit Wireless with scroll-ring because in 2020, I bought the wired version, and 3 years later, it still works. With that vote of confidence, I purchased this wireless model and have been using it happily. The scroll-ring is an excellent feature that perfectly replaces a scroll-wheel in a more conventional mouse or thumb-ball, and allows you even to click, hold, and scroll down, unlike models like the Elecom Deft Pro/Huge where there is a conventional scroll-wheel that has to be thumb-operated, making it unusable simultaneously with the LMB. I have had no connection issues ever with this; for some reason this device has BT 5.0 despite being advertised as 3.0. Buy with confidence (as long as you're ok with using a "finger-ball" of course)!

Needed a trackball or trackpad mouse for my racing simulator. Was annoyed at using a normal mouse as I had limited room on my keyboard stand. Looked in to trackpads but wasn't practical as I'm using a triple monitor rig and don't want to be swiping over and over to get across the screen. Decided to give this track ball a try and wow. Absolutely perfect for my use and an amazing product. Good materials, sensitive settings so you're not bothered trying to select something and having the mouse jump around, ergonomic and very comfortable to use. Love the scroll wheel, and the placement of the buttons are perfectly distanced from the ball it self. I have a moderately normal to large size hand so for me it's a perfect size. Didn't expect it to be this big of a product but then again I had no idea what to expect when purchasing and now after having it for a month, I can safely say I'm very happy with the size and the product overall. 100% would recommend to anyone and especially those with racing rigs, this is the best option you'll ever find. I do wish it was around $50, found it to be a little pricy but then again, everything nowadays is. And for the quality you receive, you're definitely not complaining about the price, just in the grand scheme of things, it would be nice if it was a bit cheaper.Overall 10/10

Solo un par de días después de que cerrara la ventana de devolución, el trackball dejó de funcionar con su nanoreceptor wireless. Sí funciona con el BT pero necesito las 2 conexiones porque tengo 2 computadoras. Ahora ya no me sirve. No lo volvería a comprar.

Out of the box, I was immediately impressed with the size of this mouse! I am transitioning from the previous Kensington Orbit Wireless Trackball Mouse with Touch Scroll Ring (K72352US) to give y'all an idea of where I'm coming from. Or -- just check out the photos attached and see for yourself! The new mouse fits the same space. It's not the huge monstrosity that the "expert" version of the Orbit trackball is. There ain't much information on this latest trackball -- so I literally was buying this with concerns.Hopefully this review helps others breathe easier -- and make that purchase confidently.One concern of mine was the scroll ring. The concern was that it would be fidgety, like the touch scroll ring was on the older version (in the photo you will see where I disable half the touch ring on the older mouse with putty). Well, I'm happy to report that this is not the case! The touch ring is physical, and has some friction to it. Best way to describe it is matte plastic on matte plastic — it’s not oiled, and so does not have a free-spin. It just spins when you want it to. Strangely enough, I am not finding myself accidentally bumping it either (though I will update this review down the road). So, now I have a RELIABLE scroll ring!Buttons feel the same as on the older mouse — but are positioned at a better angle for clicking.I have a weird way of holding this thing. See, despite the ergonomics, I was getting THUMB strain with the older mouse (possibly due to the angle they’re at), working at my computer 10 hours each day (4 days a week). This forced me to learn to click with my ringer finger (on my right hand), and right-click with my thumb. So with this new mouse, I am using the same fingers — but now I can also use my middle finger for the scroll wheel.Don’t forget the Bluetooth. Y’all Mac users know where I’m at: the BT connection allows you to free up an oh-so-precious USB port!EVEN BETTER: I was thinking of using this alongside the old mouse as I needed one for my work computer and one for my Mac -- but I figured out something better : I can connect the 2.4Ghz dongle to my work computer and then flip the switch at the bottom to use this one mouse with BOTH!Overall, I am impressed. I will update this review down the road as I gain more hours of actual use!UPDATE (After almost two years): So the first one got “sticky buttons” for a brief moment after a year, I was worried it was failing and decided to buy a second one as a back up. No buyers remorse here: it was worth it. Once I stopped transporting the original unit to and from the office — the button problem resolved itself and now I have two perfectly functioning units: one conveniently at home, and one in the office. I put the button issue down to the unit getting smooshed in my bag from transporting it everyday from home to the office.

I bought this trackball at the end of April, '22, so am coming up on 5 months of use and feel I can now give it a proper review. I had limited space to manipulate a mouse which required me to move the cursor a bit, pick up and return the mouse to the starting point, and incrementally moving it again until I got the cursor where I wanted it. A real pain. The trackball has solved that problem completely.My keyboard and the trackball are on a forward tilting platform. Even so, the design of the trackball resulted ergonomically in my hand being cocked upward forming a V with my arm and bending my wrist at an unnatural angle. So I had to buy a wrist support pad to elevate my wrist and align my hand and arm properly. I can now use the trackball with much less discomfort than I experienced with the mouse, but prolonged use still causes me to have some pain across the back of my hand.I found this trackball easy to use and adapted to it within just a couple of days, now being able to trackball like a pro. I use my second and middle fingers to manipulate the ball, my ring finger to rotate the scrolling ring, and my little finger and thumb respectively to hit the left and right function buttons (I am a southpaw). Using my little finger took a bit of getting used to but now I am quite adept with it. I really like that the scrolling ring used with the CTRL key changes from a scrolling to a zoom function. The software is very versatile and allows me to configure the scrolling speed with an inertia mode function. Using inertia mode is handy because I can scroll slowly in a controlled fashion and then just spin the scrolling ring if I want to rapidly skip to something further up or down. Similarly, the pointer speed and acceleration can be set. However, I have both set to fairly slow because otherwise the pointer speed becomes blinding and is almost uncontrollable. The software also permits configuring the function buttons and reversing the action of the scrolling ring. The composite settings can be saved to and restored from a file. The settings make this a great trackball for use with either hand.I have only had to remove the ball and clean it and the socket a couple of times, when the operation started to become jittery or skip. It is as simple as pushing the ball out of the socket from the rear, then wiping away any dust or debris from both with a soft cloth, and clicking the ball back into the socket.One quirk that is annoying is that at times, the left button is not responsive. It will work fine for weeks and then start working intermittently, then start working normally again. This doesn't happen often but when it does, it is frustrating. The second complaint is that the trackball is just not as precise as a mouse for cursor placement (such as while editing a document). So I keep the mouse handy and still occasionally use it for this purpose. Interestingly enough, the trackball and the mouse work simultaneously and seamlessly and I have gotten quite good at two-handed operation. I understand that reduced precision is a characteristic of trackballs in general so this is only a small negative to me. The DPI switch on the bottom of the trackball housing is a push button, and the DPI is set by repeatedly pushing the button. Unfortunately this is trial and error because there is no way to see what the setting actually is, as would be the case with a position switch. The trackball also has an on/off switch on the bottom. But this is unnecessary for normal use because it turns off automatically if the trackball isn't being used and turns back on when one of the function buttons is clicked.Overall, I really like this trackball. and highly recommend it. There is room for improvement but for the price it is really loaded with features and has really worked well for me.
