Expert Wireless

This is a fantastic, well built track ball. I could always do with fewer wires on the desk so I love that it’s wireless and I can move it around. Bluetooth also worked great for me though I prefer to use the receiver since I switch computers often. I haven’t used a trackball in a long time but I wanted to try one and I have no regrets about trying this one. I have been using it constantly for the past week and I’ve got to say, I’m very happy with it. As far as ergonomics go, I’m not sure whether it’s better than my old mouse yet. I haven’t used a track ball in 15-20 years and it uses a different set of muscles depending on how you use it which has led to some muscles getting tired the first day. Being able to use it with my pointer finger, thumb, palm, or combination of digits, however, is a huge plus for me. I can adapt my grip for comfort or accuracy easily. It has a nice pad for my hand which I do like and is comfortable but sometimes prefer not to use as I’m used to having my wrist rest on the desk by itself. I also really like that the trackball stays in place and I don’t have to keep picking up my mouse to move it around. The scroll wheel also has a nice feel and I like I can scroll with my thumb, pointer, or middle finger instead of constantly using the same one and wearing it out. After a few days, I raised the sensitivity much higher as I felt the muscle control in my fingers was adapting. It may take a bit longer before I’ve really mastered this. As a side note, I tried a mouse accuracy test online and was able to achieve a slightly lower, but nearly the same, level of accuracy on the trackball vs a regular mouse. Even though I’m not regularly clicking circles on different sides of the screen often, I believe this ball can perform just as well as a regular mouse at any task. I even tried playing some FPS games just for the heck of it and it was fine, but I think it will take some getting used to before I prefer it. The hardware itself is beautiful. I love how it looks like HAL or a robot from Portal or something. The ball is a beautiful color. The cradle is rock solid. It goes well with the rest of my black colored accessories. The only negative for me, was the KensingtonWorks software on macOS Catalina. It was a pain to install due to security settings and required multiple reboots before it would detect the trackball. Even then it didn’t seem to update settings correctly. I should mention, Kensington support was phenomenal. They were available through chat right away and helped me get the software installed and working. Unfortunately I got sick of rebooting/troubleshooting and I ended up using another piece of software called BetterTouchTool that let me really jack up the sensitivity and assign Mission Control to the top buttons, a setup I’m quite happy with. I also turned off mouse acceleration on Mac since that gave it a weird feel I didn’t like. On my Windows machine, the KensingtonWorks software installed just fine, although I have noticed I can’t jack up the sensitivity any higher in KensingtonWorks which I’ve wanted to do after developing finer muscle control in my digits. I’m sure I will find a way when I get around to it. Overall, if you want a great wireless trackball, this is an excellent choice. You won’t be disappointed.

First I want everyone to know I have used a wireless mouse for years. Second, for most of those years, it has been a Logitech Trackball. I have been thru four of them. I work from home, and I think I just wore them out. Logitech is a great mouse. I have no regrets there. Then the other day, I left my home office for an appointment and when I returned home a few hours later, it was like my electronics went haywire. My mouse, dead. I mean dead. Not battery dead. But dead, dead. Every one of my Alexas, spontaneously disconnected from the wireless internet. Wireless Keyboard - also dead - but just the batteries - I had replaced them about a month ago, and traditionally replace them once a year on average. There was no power outage. and I have everything on surge protectors. My computer was fine. It was the peripherals that were winking out on me. It was bizarre. I thought maybe it was just time to investigate a new mouse after using my backup muse for half the day and literally wanting to huck it out the window. I read blogs and reviews. This Kensington Mouse was rated the number one choice for people in my industry, and to be clear, I was hesitant. I had been a loyal Logitech user for years. But with nothing to lose, I took the plunge, made this purchase - and KNEW I would know within minutes if I would like it or revert back. I received it less than two days later. Shipping was hyper fast. The pairing was incredibly easy. Getting it out of the package was harder than the pairing process, and it came with 2 batteries in the package. Because of my wireless habit, I always keep a healthy supply of batteries on hand, but it was nice to have them encased. Within 20 minutes of delivery I had it A.) out of the box, B.) Paired to my PC, and C.) Software downloaded and buttons custom configured. SHA-ZAM! I can absolutely tell you within minutes I am loving it. I thought the scrolling ring would be a bit tough to adjust to, but no. The scroll feature is probably one of the best things I like. No regrets. If you're on the fence - work in the tech industry, YOU WILL LOVE THIS MOUSE. I can't attest to gaming use, but then I'm not a pc gamer. Without hesitation- I know this will be my new go to. So worth the money.

I like this trackball mouse, but the scroll wheel is positioned awkwardly. I keep accidentally scrolling up or down when I'm trying to move the mouse. I might have to try filing down the texturing on the scroll wheel to see if it stops my fingers from brushing it so easily. I wish that there was a wireless version of the Slimblade, which scrolls by spinning the trackball along the z-axis; it sounds a lot smoother. Update 3 years later: while I do still occasionally scroll by accident, this doesn't occur with enough frequency to be disruptive. I have also had an opportunity to try the slim blade, and I like my current one better than the slim blade. I have purchased four in total, two for home and two for work. With the programmable buttons, this makes it easy for me to have a right and left hand mouse at the same time, which is great for my carpal tunnel. If I start to feel even slightly uncomfortable, I can just switch hands instantly without issue. And since my monitors are actually quite large, if I want to zip across my workspace, I can use both mice at the same time to get from one side of the screen to the other quickly. You will notice some stiffness in the scroll wheel at first, but it will completely loosen up within a couple of weeks of use. And the mouse itself has held up well under frequent use. I don't use the built-in wrist rest, as I prefer a bean bag for ergonomic support. In summary, 4.5 out of 5 stars. I am all but certain to buy this again when mine eventually start to wear out.

February 04, 2024 Update: Track ball works well. Doesn't seem to have but one issue and that issue is probably my problem. The scroll ring sometimes and my fingers don't jive causing me top hit one of the corner buttons. I must further practice, do much more practice. New Thought, 31dec23: Dragging and dropping, for instance, an email in MS Outlook to a folder can be challenging. I have not figured out the best method. Am looking for any ideas... 28dec23: Overall, I like the trackball and am tentatively at about 60/40 thinking to keep the device. Has many interesting functions and possibilities. Will know more as I work to better use the device. I definitely need more practice with the trackball because my long-term use of a regular mouse allows me to be pretty fast with the mouse. Early Pro’s: 1. Bluetooth connecting is really easy. 2. Kensington Works software for the trackball is easily downloaded for the device and pretty easy to use although it is not overly intuitive. 3. Large trackball seems very good particularly located in the mid position. Is good for me with some tremors and a shaky thumb compared with a side trackball. The middle trackball is far superior, for me, to the side mounted track balls. With practice, I am sure that I can rapidly move the cursor via the trackball. 4. Left Click/lower left button works pretty well. I seem to have it pretty well figured. Using my thumb for this button. 5. Right Click/lower right button not so handy as the Left Click button. Learning. May do better with it after more practice. 6. Have not really used upper two buttons, yet. 7. Scroll ring works well. Don’t have clicking noise that other reviewers have reported. 8. Don’t know how the battery life will be; we shall see. 9. Don’t yet know how the wrist rest will be although it seems okay with this short time review. Early Concerns: 1. Will take considerable practice for me which I am willing to do to become proficient with the trackball. 2. Have already learned to be very careful not to simultaneously touch the trackball while trying to scroll. Is easy to do! Result is my inadvertent action takes me some crazy place I did not want to go!

I did a lot of research when trying to find the perfect solution to my problems. I’m a developer and I do a lot of work with the keyboard and mouse. Normal clicking and wrist movement hurts over a long period of time for me, so I decided to get something more comfortable. After everything, I decided to get two mice and compare them. I got the Elecom HUGE and the Kensington Expert. Here goes the breakdown. I will comment on resting comfort. To clarify, this would be the comfort of simply resting my hand on the mouse without actually using it. This is different because sometimes you don’t want to actually use the mouse but you want to test your hand. I found the Elecom HUGE to be the most comfortable. It had a great padding and it’s shape was made to fit in a palm. However, I will now reference functional comfort. This would be the comfort of actually using the mouse. After a while, the HUGE began to strain my thumb from using the scroll wheel. The Kensington has never given me any kind of strain for using it. It’s design is meant to be ambidextrous so it’s not going to fit in your palm the same, but it is nice because you essentially use your whole hand to use it. It balances use and doesn’t strain any part of your hand. The palm rest extension on the Kensington is comfortable. It probably could be a lot softer, but it hasn’t given me any discomfort so I’m happy with it. The only thing I had to sacrifice when deciding to keep the Kensington was the functionality. I loved the buttons and programmability in the HUGE. There were a lot of buttons and it felt nice and convenient. However, I was pleasantly surprised with the software that the Kensington provided. There were a lot more options for commands to program to each of the buttons. I felt like I had to actually choose between useful functions. The HUGE had a lot of functions but not a lot of useful and Mac-specific ones. The Kensington has a lot specific to my Mac and made it nice to program. And it was not just the four buttons. The software allows you to program the four buttons separately, the two top ones together, and the two bottom ones together, giving you a total of 6 functions you can program to the mouse. The quality is by far the best and it’s a great mouse.

It's really frustrating just how poor this product (Wireless Expert Trackball) is despite the price you're paying. I remember the red trackball used to be a cool mouse that professionals used in their studios or desks. Now I question why. Here's a quick summary of things. I was going to write out in detail everything, but here's just the points: 1) Scroll wheel doesn't work. A mouse needs to do at least, AT LEAST, two things: 1) Click on things; and 2) scroll. This mouse does only half of what is expected from it.; 2) I thought it was just software/driver issues, so I double checked everything. Apparently the manual packaged with the product is outdated and tells you to download an old version (KensingtonWorks) instead of the new version (Kensington Konnect) despite the change earlier this year. Regardless, old or new - nothing fixed my issue; 3) Upon further research, it seems that the scroll wheel being broken is a common issue due to sloppy alignment or placement of the IR transmitter/receiver; 4) I requested a replacement, completely understanding that sometimes you just get a faulty product. And if the replacement works as intended, then cool. I was approved immediately for a replacement and notified I would get a replacement next day. Sweet. 5) Next day came, no replacement. Was told that there is a delay due to supply issues and they'll let me know when I'll get a replacement. 6) I'm literally looking at the product page right now and if I pay $87 (again), I can get the product delivered tomorrow. But since they have my money after sending a broken product the first time, they're telling me to wait and see when they can send me a replacement. I'M LITERALLY LOOKING AT FREE DELIVERY FOR TOMORROW IF I JUST BUY ANOTHER ONE. I got this because I do a lot of editing - for video and photography. I also do a lot of work involving excel sheets, accounting software, creating forms and etc etc Boring computer stuff mostly. My current trackpad isn't up to snuff with how fast I tend to work anymore so I wanted an upgrade. This product is great, I won't lie. I really like it. I've been using it to at least see if a trackball does make a difference, and does it ever. The trackball tech is really great compared to standard mouse and trackpads. But how do they mess up the most common feature of all mouses? I can live with a faulty product every once in awhile. That's life.That's why there's return/replacement policies. But between this being a common issue apparently for years now, the fact that they're still sending outdated manuals and material despite new software being needed to use their product, and having my replacement cancelled from next day to "we'll see" unless I just buy a whole new product, I'm left extremely disappointed. This is the first 1-star review I've given for a product (that I can remember), and I tend to buy a bit from Amazon and am even part of the Amazon Vine program where I review things from time to time. But this experience just left me extremely disappointed.

The reason I bought this trackball mouse may be different than others. ARCADE GAMING!!! More on that in a bit.. However, I have found that this is probably THE BEST accessory I have purchased for my computer(s) in many years. And that's saying a lot considering the number of goodies I have bought. I have 4 mice sitting here. All of them are wireless. 2 of them are gaming mice with many buttons, DPI changers, etc.. They all do exactly what they should do, and they do it very well. However, as one that uses my computer at times 20 hours at a time my hands can get very painful holding/using a mouse. I use an ergonomic keyboard and will NEVER go back to using a straight flat keyboard again. I had a trackball (wired) from Kensington many many years ago (like back in windows 98 era I think) and loved it. So I have had some experience with them. I did a couple days of research into which trackball mouse I would want. I looked at the finger ones, thumb ones, marble, full size, etc.. I read literally 1000's of reviews. (Just a hint, I ALWAYS read the negative reviews first. Show me the issues people have so I can decide if it is worth it, just in case....then show me all the positives.) The reviews of this one over many different sites sold me. And of course, since I buy via Amazon, I have NO ISSUES if I don't like it and want to return it. So, why exactly did I want one? Well, because I LOVE to play arcade games. And my favorite arcade games are old one like Crystal Castles, Centipede, Star Wars, Missile Command, Golden Tee (golf), etc. And to play these where they simple don't suck, you MUST use a trackball. Well, I sold my video cabinet years ago which had a trackball panel with it. So I thought I would give this a try as a replacement. WOW!!!!!! This is a dream when it comes to playing arcade games that utilize trackballs. The ball spins so beautifully and has exactly the right momentum force that the games play exactly how they are supposed to. As for use as a mouse for the PC? Again..... WOW! My hand does not fatigue at all, even after 10-15-20 hours of constant use when doing design work. I LOVE the fact that you can program the 4 buttons to do whatever you want PER APPLICATION!!!! In other words, you can tell it to use button 1 for this function in MS Word, and that function in Photoshop. And the scroll ring???? OMG I have fallen in love with this thing!!! While I wish I could use it in games that use a spinner (tron, arkanoid, etc.) I have not found a way to do that. It simply scrolls pages up and down. And can also be used for zoom effects zooming in and out. LOVE that feature. What makes it so much better than any mouse wheel I have used (and some of my mice are $$$$$) is that you can program the speed/range. Same with the ball speed. You can adjust it for how far it will move, acceleration speed, and how fast overall. I can't boast enough about this trackball. And while I got down to two choices....I am so happy that I picked this one. I am selling my mice now...(may keep one, just in case) but will never NOT have one of these trackballs on my desk.

I've been writing about - and reviewing - trackballs for decades -- probably more than 30 years. I've been working with trackballs since the days before they were using the oxymoron 'trackball mouse.' A trackball is NOT a mouse. It's a trackball - it does some of the same things as a mouse, but it ISN'T a mouse. It's like 'car bicycle' Both get you from point A to point B, but you really can't confuse the two. Trackball mouse is just stupid marketing speech. Anyway - back to my review. I've been using trackballs for a LONG time. I don't like to use a mouse - it takes up a lot of desk space, it requires a lot of arm movement, it usually requires a smooth scrolling surface, the buttons have stopped working (on the mice that I DID use). I prefer a trackball over a mouse. I prefer a trackball over a touch pad. I've used the Logitech thumb mouse - and it was my 'go to' device until I got a wired Kensington trackball for a then 97-year-old friend who didn't have the muscle control to use a mouse. I used that trackball, too, and fell in love with the scroll wheel. Even though I didn't want a wired device, I bought one for myself. I got tired of pulling the wire when I walked away from the computer, and it got tangled under my foot. I wanted a wireless alternative that was similar to the wired Kensington trackball that I had been using ALL THE TIME. I realized that this wireless trackball was heavy. I realized that this wireless trackball was large. I realized that this wireless trackball had a massive ball. After it arrived, I had to figure out how to insert the batteries (there's a notch in the battery slot in the case for the Positive end of the battery - you angle the negative in first, then slide the positive end down. Once I figured that out, it was easy. I didn't see a dongle in the box, so I concluded that the dongle was in the battery compartment -- it was. Bluetooth didn't pair. Instructions weren't very helpful. In the case of bluetooth for this trackball, I suspect that the signal from my bluetooth dongle is too weak to talk to the trackball. For me, it doesn't matter - radio frequency works fine. I use my trackball differently from most users -- it's sitting on my right leg, near the knee. It's hefty enough that it won't slip off. The angle isn't a problem for me. The scroll ring on this trackball is very smooth - perhaps Kensington has resolved the issue that others complained about in their trackballs. I would have preferred larger 'nubs' on the top of the scrollwheel, like some other Kensington products, but have gotten used to this scrollwheel. (Tip - for scrolling a large area, you can hold your finger on the wheel, lift your hand, and scroll the wheel around the ball). The ball and buttons work fine for me - I click the lower left button with my thumb, and the upper right with my right ring finger. The top left and lower right buttons haven't gotten much use, yet. I've configured the buttons with the Kensington software, but it didn't seem to want to make top left into a middle button and lower left into a click. I'll work around it. I've only used this for a few hours. I can't comment on durability or battery life. I'll probably append to this review after a few weeks or months of use (assuming it doesn't fail in the meantime and I wind up returning it). For now, it's probably my pointing device of choice. If that changes, I'll report on it. A few more things -- I'd prefer that the mouse was held in, somehow, so that I don't worry about it dropping out. I'd like to see Kensington and Logitech getting together on the one aspect that they could really work on -- to help the user, set up the protocol that lets the Kensington wireless products work with the Logitech Unifying Receiver -- I'm using Logitech with two thumb trackballs, and it would be great to NOT have to dedicate a USB port to the Kensington USB dongle when I've got a perfectly good USB dongle for the Logitech products. DO YOU HEAR ME LOGITECH? DO YOU HEAR ME KENSINGTON? DO THIS FOR THE CUSTOMER -- IT'S GOOD P.R., AND GOOD TO PROMOTE STANDARDS UPDATE - ONE WEEK LATER (9 20 18) At first, I thought that this trackball was great. After a few days, it started skipping - I'd move the ball, but nothing happened on screen (this was, of course, AFTER it woke up). I tried blowing dust out of the area where the ball rolled, I tried wiping the ball with a cloth - this didn't seem to help. It seemed at times that I couldn't roll it from the top - I had to roll from an area just above the scroll wheel. I've had issues like this with other trackballs, but I'm not sure what resolved them (if they WERE resolved). I'll give this a few more days, try contacting Kensington, and may wind up - even though I'd prefer to keep this ball if it worked properly - returning it for a refund. I've deducted a start for now -- if I can get this to work well, one or more stars may come back. The bluetooth doesn't work, either. I called Kensington Tech Support and theyre replacing the trackball -- I'll report on the new one, after I've tested it for a while.

Desde que lo uso ya no se me cansa la muñeca, a pesar de que lo utilizo unas seis horas al día. He ganado en productividad porque, gracias a su gran bola, puedo situar el cursor exactamente donde quiero a gran velocidad. Los cuatro pulsadores de que dispone son grandes, sensibles y cómodos para usar. Aunque puede configurarse para que la pulsación conjunta de dos botones adyacentes sea equivalente a otro botón, esto no me resulta práctico porque es difícil hacer la pulsación simultánea.

A trackball is nothing I would have considered in the past as most of my PC time is used for gaming and being able to do work has always just been a "bonus" of the platform. However, over the course of the wonderful year of 2020, I had to find solutions to working from home and purchased not just one, but two trackballs. I first started with Logitech's M570 (wireless) and followed it up a couple of months later with the Kensington Expert Wireless. Chances are that if you're seriously considering transitioning to a trackball, you are looking at exactly these two models or their wired siblings. Both solved a very simple problem of making the most of confined space. For my gaming and personal PC, I have a typical desk setup with a brick of a gaming mouse, but for the work laptop I lugged home with me, the idea was that it was a temporary thing and I'd be back in the office with a full desk in no time. Three quarters of a year later and the work machine is growing roots in an old TV table. I managed for a very long time as I was quite comfortable with simply using the built-in trackpad, but when they replaced my machine with a new one, I could no longer work without wanting to throw it out the window. The 'brilliant' minds that designed the new trackpad clearly never used one as they removed the physical buttons that bisected the pad and made the pad itself one giant button that would only right click if you used the very bottom right corner. So now I needed a mouse, but TV trays don't have the runway for effective mouse use. Enter the trackball. Since trackballs stay put, they can sit comfortably in a small space and you still have full use of your cursor. The second thing both trackballs solved was the right-click issue. While the M570 has more traditional placement of buttons like a regular mouse, the Kensington Expert (herein "Expert") has four fairly large buttons that can be tapped easily regardless of what hand position you take. Since the laptop's trackpad cut the right-click distance by 2/3rds and I live and die by context menus, I needed that functionality without feeling the need to break equipment. The above issues are solved by pretty much any trackball device available in the market today, so what it really comes down to aside from general reliability and longevity is preference. First off, while the M570 seems sturdy enough, the Expert feels like a tank. It has a fairly large footprint compared to the relatively mouse-sized M570, but the Expert also has a much larger ball (maybe three times bigger?) and is heavier and kept in place with rubber feet. As mentioned above, it has four large programmable buttons surrounding the trackball and a rubbery ridged wheel that provides you with your scrolling (compared to Kensington's Slimblade which has you twisting the ball in the socket to scroll instead). The Expert uses the bottom left button (by default) for left click and the bottom right for right click. Since the ball is finger operated as opposed to thumb-operated M570, you typically use your thumb and pinky to click and right-click respectively. It takes some getting used to, but it really becomes second nature pretty quickly. On top of that, you get two extra programmable button assignments by clicking the top two or the bottom two buttons together. Despite its wider footprint, the Expert has become my go-to device for work while the M570 has been repurposed for the media machine I have connected to my TV. While it comes with a very sturdy wrist pad to help with your ergonomics, since I sit higher than the Expert instead of level with it, I find it feels better without the pad attached. The larger ball is much easier to manipulate and makes more logistical sense than when using the thumb ball of the M570 and Kensington's software allows you to set up keyboard hotkeys to assist with accuracy. For example, I can hold the Ctrl key to drastically slow down the cursor (this is completely customizable) so I can select specific things or position the cursor with precision. For cleaning, the ball is held in the device by gravity only and can be easily lifted out without having to lift the base unit (and it's kinda fun to do that anyway). Underneath you'll have access to the sensor as well as the three beads or skates that the ball rides on. I don't find that the ball is a dust magnet, but normal use will see crud accumulate either on it or on the skates. It's easy to simply lift the ball and give everything a wipe down. There's only two things that I am nitpicky about when it comes to the Expert. First, the ball has a very high profile (exactly half of it is exposed) and while I find it very comfortable to use throughout the day and experience no wrist strain whatsoever, it would have been nice if the 'horizon' or the plane of the base unit was a bit higher and the ball sunk a bit lower (things addressed in the Slimblade). The second thing is that this thing puts itself to sleep, which is admittedly a good thing. However, you cannot wake it by rolling the ball or scrolling the wheel; you must click one of the buttons to wake the device from sleep, but the click is actually registered with the OS and is not thrown away. Therefore, unless you're expressly positioning your cursor safely when you go idle, then you need to be careful on what button you press to wake your device. Neither are dealbreakers, but I really find the registration of the wake input to be weird. Overall, I am very happy with both of my purchases, but the Expert won out as my day-to-day solution for work. I would never use the device for gaming (at least competitively), but its customizable configuration from speed to keystrokes with Kensington's lightweight software easily make it a power-user's device. It may be unintuitive at first, and I was always first in line to mock these devices, but I have completely turned around on them. I think wherever I go in my professional life, the Expert will come with me.

It works quite well, but If I compare quality or at least the feel of quality it is not the feel belonging to 100 euro's. I had a logitech before (but problems with my thumb) and if you take that as standard, this kensington has the feel of one of 30 euro's. But maybe the quality is there and it will prove that to me by functioning perfect for the coming 5 years and I can come back for more stars. The software works, but isn't very nicely done. Again, it works so when you have set it, you don't have to do till you take a new computer. Tip for the manufacturer. Don't present a drawing where the dongle had a place in te mouse and then hide it in the cartons :) So for sofar a 4/5 for function and a 2 for the way it looks for that amount of money, making it a 3 stars item. Hope to come back to add stars as the quality is better then it looks at first sight.

Love a trackball as it’s much easier to control.

Great trackball. Easy to connect; just plug the dongle in, and it's good to go. Really good size of trackball allows me to use three fingers to navigate precisely with my non-dominant hand. Comfortable to use from the couch too. The buttons click nicely and the scroll wheel works well. It's definitely a little bit pricey, but definitely worth it to be able to rest my injured dominant hand but still be able to enjoy good precision when using my home PC. The ball comes out easily to clean, so I wouldn't want to take this loose in my bag into the office, but that isn't really a consideration for me since I've switched this one out for the Orbit Fusion, which I'll take to work instead.
