I have a weird way of holding this... and it works
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!

I was looking for a more ergonomic mouse to compliment my ergo keyboard. This does the job nicely, and is priced right. My first impression on the Amazon listing was that it could also be used like a traditional optical mouse, but that is not the case. It's almost better that it is stationary, however, as I have limited desk space. The trackball and mouse buttons feel nice, the Bluetooth connection works very well, and the build quality is very good. Would recommend!

5.0 out of 5 stars Excellent Starter Trackball
Reviewed in the United States on February 18, 2024
Color: K72337USStyle: wired usbVerified Purchase
To be fair, the Orbit with Scroll Ring is more than just a good starter finger-operated trackball - it's practically the only one on the market since Logitech stopped producing the Trackman Marble, but I digress...

The Orbit with Scroll Ring is wonderful - I've been using it at work since my purchase. I now have virtually no errors caused by mouse movement while clicking, and the ergonomics of it don't agitate my tennis elbow like traditional mouse use did. There was a certain 'break-in period' where the the ball could sometimes feel 'sticky' (as in, needed a little extra force to start it moving), and this kind of use in general takes a little getting used to, but just a few months later it feels so natural and accurate that I feel like I could play mid- to high-intensity games on this thing. The only thing holding me back is a middle click for games that use one.

I've actually been enjoying my Orbit so much, that I got another trackball for home - but I still feel much more comfortable with this one. If only it had one or two more buttons... But for an entry model or for work applications that don't need a middle-click, this is an excellent choice.

4.0 out of 5 stars Great wireless trackball option, but would benefit from some minor improvements in design.
Reviewed in the United States on October 24, 2023
Color: Black-RedStyle: wirelessVerified Purchase
I am coming from a Logitech Marble Mouse, with over 15 years of usage on it. The Marble Mouse has finally hit end of life and it was time for a replacement. I was able to briefly try some of the Elecom mice, that a friend had purchased.. and I was overall disappointed with those. The form factor was either way too tall and short length wise, or the ball was just way too big/heavy (maybe they will figure out a good design eventually). I did use an old school Kensington blue trackball mouse back in the day, so I am familiar with this general mouse shape. I have used this new Kensington for a few months now, including gaming.

So anyways onto the Kensington mouse:

Ergonomics/comfort: 7/10 It's plenty acceptable, but as some other reviewer said, the button placement relative to how you control the ball, is a bit "off". I don't understand why the buttons are not shifted back, at least a tiny bit further on the device (with exception to internal design restrictions). If you set up your hand on the mouse, and press the center of the buttons, it places the ball more towards the palm of my hand, than the finger tips, which isn't ideal. I sort of rotate the mouse and so on to make it work. I do not use the wrist rest it comes with.

Scroll wheel: 10/10 Excellent idea, finally able to have a scroll wheel with a trackball, as the Logitech always lacked this feature. I find it very comfortable and satisfying to use.

Ball Accuracy/Smoothness: 10/10 Everything is solid in this area, precision of the ball relative to mouse cursor is so good (night and day over the old Logitech). The DPI adjustments are fine but I don't use them often.

Button/Switches: 6/10 Honestly wish the switches had a lighter feel and were more quiet. They are rather slow in actuation and a bit stiff. This makes it more fatiguing on the hand as well. I guess we'll see how they feel after a good period of usage. I would like to see a change in this for sure (I doubt it but one could hope).

Wireless: 10/10 Using the 2.4Ghz, I have no complaints, no lag or anything either.

Gaming: 7.5/10 Honestly it works just fine for me, having the extra resolution ball sensor makes everything so much better, wish I had this a long time ago. Sometimes I hit the scroll wheel by accident. Depending on the game and in general, the slower/stiffer/longer travel switches make for a more fatiguing experience than on the old Logitech; or basically what you'd get on most laser/optical mice on the market.

Build/Material Quality: 9/10 Of course this could change, but initially the build quality seems perfectly fine. I couldn't find any defects. The body feels durable and generally the same as any other good mouse. I like the amount of padded feet it has, and it stays put.

Overall I'm satisfied with this as a good wireless upgrade/replacement of the Logitech Marble Mouse, though I'll say the shape of the Logitech was a little more comfortable in the palm area. I'll update if anything goes wrong.

5.0 out of 5 stars Definite keeper!
Reviewed in the United States on February 18, 2011
Color: K72337USStyle: wired usbVerified Purchase
I've had the trackball for about a month now. I bought it to replace the wireless Mighty Mouse that came with my Mac 'cause it ate batteries like no tomorrow. VERY, VERY pleased with the trackball. It took me about a week to figure out how to comfortably use it as I had exclusively using a Wacom tablet in place of the mouse, before deciding to get some sort of mouse.

The software: To start off, for those reading reviews of those complaining about the program, you CAN plug and play it. You don't actually need the program for the trackball to work. The mouse adjustments that you can make in the System Preferences will still work for the trackball. However, in order to access the additional features, you will need to download the software. It's a very easy process, just go to the website, download and install it (the instructions come in the packet). The icon will show up in your System Preferences window under the Other header. I don't know where it appears for Windows as I've only transferred the trackball between our Macs. In the trackball program, you can adjust the usual features (scroll speed, click speed, etc) and also the left/right combo click which you can set to do stuff like go back or forward. The program also allows you to choose which direction to have the scroll ring turn to go up or down. The default is set to clockwise for scrolling down.

The buttons: overall, they're pretty standard in function. However, I do find that sometimes in certain programs like a Flash game, it won't always want to click on the first try, so I wouldn't recommend this for gaming purposes for games where you do need an immediate response. All other uses, I haven't really noticed any problems. I love the option of being able to set the dual click to do something :) As a first time trackball user, something else I also had to remember to do was take my fingers off the ball before clicking as I often catch myself nudging the ball when I click and then missing the spot I wanted to click. Same goes for the scroll wheel. I seem to subconsciously fiddle with that too.

Trackball: No issues with it at all. It took some getting used to with adjusting from a mouse or my tablet and I found myself trying to click on the ball itself a number of times. *lol* But no fault of the device.

The scroll ring: So far, I haven't experienced any of the major problems that have been complained about so far. Up till about a week ago, I hadn't gotten around to looking into the trackball's software and once I did, it made a huge world of difference with how smoothly the ring scrolled. It felt a little slow, previously to the point where it sort of staggered sometimes. I love how I can now just give the ring a quick flick with a finger and I'll be back at the top of a web page. I've actually caught myself trying to do that with a scroll wheel on a mouse at work and wondering why it just inched up instead of flying up where I wanted it! Keeping in mind of the complaints though, I have been careful with the wheel and trying not to use it when I don't feel I really need to, as not to potentially abuse it to death as I really like it. So if I'm scrolling to skim an article or search it for something, I'll use the scroll bar on the browser, which with the trackball is pretty effortless.

Extras: It includes a wrist rest that you can attach to the end of the base. I didn't bother with it as my desk has a built in one.

Size of whole unit: it's a decent size for me. My hand length is about 7 inches and the size of the unit allows me to perch my fingertips on the ball and comfortably roll forward to the middle joint of my fingers if I want to do one long continuous drag. I've play tested some older trackballs in stores many years ago when the majority seemed to be a lot larger, so this works fairly well.

Advice: if you find yourself needing to clean your trackball, don't use Clorox wipes. It leaves a sticky residues that slows down the ball's spin. I just pulled out the ball and washed it with hand soap and water, wiped out the dust in the holder, dried off everything and stuck it back in.

User troubleshooting: If you find that your hand is more tired using the trackball than a regular mouse, try adjusting your chair height. This can make a very big difference. If you have an arm rest on your chair, take advantage of it and adjust your chair height to make the rest level with your trackball.

Uso meu trackball conectado numa dockstation usb-c universal e achei ótima a compatibilidade com windows, Linux e Mac. Oferece ótima ergonomia pro pulso e é muito fácil de extrair a esfera pra limpar. Pra que pagar mais caro pra ter algo sem fio? Só pela mobilidade? Satisfeito por usar num lugar fixo por cabo USB.

5.0 out of 5 stars Amazing quality and perfect for my use

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.
