Review: Carpal, cubital, and radial tunnel relief. Plus, this thing just works. - Here are my operating system specifications: * Hardware: MacBook Pro 2020, Apple M1 Chip * Software: macOS Ventura 13.5.1 UPDATE: After 5 days of heavy use (10+ hours per day), there are a only two issues I've noticed that have no impact on my love for this device, but that I'd like to share to make sure others who experience these issues do not become frustrated. Issue #1: Continuous heavy pressure on the left or right side of the wheel can cause the wheel to slide slightly ajar, degrading the function of the wheel and whichever button the wheel has been pushed towards. I was pressing my thumb on the right side of the wheel unconsciously, and found that eventually this pushed the wheel towards the left, causing some accidental clicks of the left arrow "" as left-click and right-click, respectively, because I have no use for the "back" and "forward" web browser functions that are the default. I also reprogrammed all of the media player buttons to more useful actions (e.g. Copy, Paste, Undo, Redo, and Tab). For the most part, the custom-programmed buttons all function as expected. Occasionally, however, I have to re-open the "ELECOM_Mouse_Util" GUI and click "Apply" to re-apply all of my customizations. The GUI remembers all of my button preferences, so I don't have to do any tedious resetting in the GUI, I just have to quickly open it up and click "Apply," and my customizations are automatically applied to the device. I recommend keeping the GUI in your dock (on Mac) for convenience, since you might have to do this a couple times a day. Other than that, I just recommend being disciplined about resting the device upright on its docking station when you switch to the keyboard. I've been lazily setting it in my lap, where it shifts around, activating the rollerball and moving my cursor around the screen. This is my fault, not the device. These are the only issues I've noticed in the past five days. On the upside, I've noticed that updating dense software code files has gotten WAY easier. After updating the media player buttons to my most frequently needed actions while coding (Copy, Paste, Undo, Redo, and Tab), I find that I can make most of my code updates with my hands resting in my lap or at my sides, and only spend about 20% of the time actually touching the keyboard. I'm able to go a lot longer now without any numbness or pain setting into my wrists and hands. ORIGINAL: I have only been using this little thing for an hour and I am already crying tears of relief. I have been searching for a device with this exact design for three years, and I cannot believe it actually exists. After installing the utility software, the mouse worked immediately, right out of the box. The software package seems to have auto-detected my default OS language, and the program opened in English (no need to select "English" as the default language, as indicated in earlier reviews). I also did not need to download Rosetta 2 to get this to work on my MacBook Pro, even though I have an M1 chip (as indicated on the manufacturer website). The mouse was so easy to use, that I actually used the device itself to customize its own functionality through the utility GUI. I am shocked at the level of customizability across the 10 (!) onboard buttons, and how easy it is to quickly update this functionality in the utility GUI. If you look at ergonomic keyboards with comparable customizability, you will find that (1) they are very, very expensive, and (2) full customization usually requires some code, and cannot be achieved with a simple, user-friendly GUI. In my opinion, the GUI software that accompanies this little device is easily worth an additional $300.00. The "loose trackball" complaints are unfounded. The trackball slightly lifts out of the cradle when you tilt it > 90 degrees on its side (or upside-down). It DOES NOT fall out of the cradle, even if you hold it upside-down and shake it violently. This is how all trackball devices work. You can read reviews of the highest-rated trackball mice on Wirecutter, and you'll find the same issue. A "tighter" fitting trackball design would have reduced functionality, and you would not be able to pop the ball out to clean it (which you do actually need to do every so often, as gross stuff gets trapped in there and degrades functionality after a while). When I use this mouse with my arms straight down at my sides, the trackball lifts slightly out of the cradle. I do not find that this affects the functionality at all. The trackball still settles exactly where I left it (it doesn't continue "spinning around" when it lifts out of the cradle) and the on-screen pointer position is stable. If you're really having issues with pointer precision, decrease the DPI. The design of the device is so intuitive that I didn't require a single minute of acclimation. My hands just sort of knew what to do, even though I have never owned a trackball-style mouse in my life. I found that I naturally started switching between using my thumb and my forefinger to operate the trackball. So, I changed the "back" and "forward" buttons on either side of the scroll wheel to "left" and "right" click. This allows me to constantly change my grip on the device, which lets me switch off between types of movement in my thumb and forefinger. This sort of rotation between types of movement, and between hands, is critical for managing my the symptoms of my repetitive strain injuries. I need to use a computer mouse continuously 10-14 hours per day, 7 days a week, in order to do my job. I often have to do difficult design work that requires precise control over graphics in clunky presentation and statistical software (e.g. STATA's graphic editor GUI that is unavoidable given the limits of code-based graphics customization). Unfortunately, I have severe carpal *and* cubital tunnel nerve compression on both sides, complicated by a botched surgery on the right side that resulted in tendonitis and neuropathy (my medial, ulnar, and radial nerves are all damaged). Holding my elbow bent at a 90-degree angle causes my ring and little finger to go numb, and severe stabbing pains in the knuckle of my ring finger and in my upper forearm. Articulating or putting any pressure on my elbows also causes pain and numbness. Any pressure on my wrist, or continuous finger articulation, or gripping, causes my thumb, forefinger, and middle finger to go numb, and causes pain in the base of my thumb, in my palm, and in the back of my wrist. So, pretty much any desktop mouse exacerbates my symptoms, no matter how "ergonomic" the design (vertical, trackball, rollermouse bar, external trackpad, pen-shaped mouse, whatever). I need a mouse that I can use in either hand without having to exert a lot of force, without having to articulate my fingers very much, and while letting my arms hang at my sides. Until today, I thought this was an impossible request. This mouse feels like it was made specially for me. Additional features and responses to earlier reviews: * My Mac is able to track and display the battery level in the Bluetooth settings, so if you use rechargeable batteries and carry around an extra pair and/or a little charger, this thing will be just as convenient as any wireless peripheral that takes a usb charge. * The scroll wheel customization is great. You can set up "flywheel" to work in any program. Flywheel auto-scrolls in whatever direction you were turning the wheel at the time it was activated. The number of "revolutions" is the number of times you need to rotate the wheel to activate flywheel. You can choose from 1-5 revolutions. The scrolling speed is how quickly the page scrolls automatically when flywheel is activated. I messed around with these settings a bit and was able to get close to the two-finger flywheel scroll I'm used to on my Mac trackpad, but found that I actually prefer a slower auto-scroll. * The buttons are actually infinitely customizable. The only restriction is that at least one button on the device (can be any of the 10) is reserved for left-click. The other 9 buttons can be programmed to do whatever you want. For each button, you can select "arbitrary key" and then program a set of commands that will be executed by that button. You can also select a "gesture" button, and then use the Gesture tab of the GUI to set up gestures. Basically, you select sets of commands that will be executed whenever you are holding down the "gesture" button and perform some on-screen gesture with the mouse. * It is lightweight, not "cheap." If you have an RSI or arthritis, you will appreciate how lightweight the device is. Heaviness is not an indicator of quality. Buttons are responsive without requiring very much force, and provide the satisfying "mechanical" feedback clicks that haptic devices just can't reproduce. The "skin" is also slightly grainy (versus slick) which makes it easier to grip loosely, even in sweaty hands. The trackball itself is substantially heavy and does not float around in the cradle.
Review: Good overall, a few niggles, does feel a bit pricy, software great. - Would have liked to put 3.5 stars but can only do 3 or 4. Have been using this for just a couple of days and have mixed feelings but overall positive. Will update when I've used it longer and made a decision as to whether to keep it. Reading some of the negative reviews, it seems like people just don't understand how this works or how to use the program - which really isn't that difficult. I'm not sure where "broken english" is coming from either, given that almost everything in the program is only 1 or 2 words like "main button" or "sub button" or "keyboard input". It's really quite self explanatory and I had the mouse connected to my mac and the software installed in less than 5 minutes. If you're older or not very computer literate, you might need to have some patience or get someone to help you set it up initially but I'm not sure you even need the program and if you're that computer illiterate, I'm not sure what use it would be to you anyway. I actually found the program great, you can assign almost any function, to almost every button (except the dpi button and on/off switch). You can also create profiles for different programs, so buttons do different things depending on what program you're in. Exceptionally useful for a graphic designer switching between InDesign, Photoshop and Illustrator all day, all requiring different shortcuts. I've specifically been looking for something like this, which I can use in my left hand as I have awful pain in my right hand from repetitive strain. I've certainly noticed a difference already in how much better my right wrist and hand feels and it was very easy to use in my left hand despite being right handed. My only gripes would be that the roller ball isn't terribly smooth. 90% of the time it's fine but there's a small area which seems to judder when you're on it and it makes it difficult to click specific spaces, which is often what I need to do. As others have said it does feels a bit loose and that may be part of the problem but it certainy isn't falling out. I'm assuming it must come out somehow to be cleaned but I havn't gotten far enough to figuring that out yet. The build quality is actually pretty good over all, I would not confuse how lightweight it is with it being cheap or poor quality at all. The left and right buttons either side of the scroll wheel do need to be pressed in the middle or lower down rather than where my thumb naturally sits nearer the top of the button but I think this is a design flaw rather than a cheap build - it is intentionally not "clickable" at the top, because that's where the pivot is. It also wouldn't be an issue if I had slightly bigger hands or longer fingers. My hands are very small so it does make it a little difficult to reach the buttons right on the bottom but it's not a deal breaker at all and those click perfectly well. I have quite a large screen too and a second screen next to it so it has been a bit tricky to get the dpi I need in order to move around the large area and also do the more detailed things in smaller precise spaces. I'm going to assign the dpi to another button so I can more easily switch dpi while holding in my left hand and see if that makes it better. I had a similar issue with the Logitech MX Ergo S which I ultimately found a good middle ground for without the need to be switching all the time but ultimately had to send back because the tilt of the mouse wasn't enough, I still had a lot of pain in my right hand and it wasn't able to be used left handed. It does feel a little bit expensive, especially as the Logitech mouse I mentioned above was around £80 and did feel a lot nicer with the roller ball, which let's be honest is the main function of the mouse, to move around the screen. Even though the quality is good and the program it comes with is great. There was a review saying it was required but I'm pretty sure you don't actually need to use it either. I don't know why you wouldn't use it though because it's great and gives so much more functionality. I'm not sure if this will replace my drawing tablet which I've been using as a mouse for over a decade, and would still be using if I could do it left handed, but at the moment I'm likely to keep it and switch between the drawing pad, normal mouse and this, depending on what I'm doing at the time, and so my right hand and wrist can have a break more often.

## Questions & Answers

**Q: Does it have Bluetooth? Can i use this on phones?**
A: It uses a dedicated USB-A Bluetooth dongle. You might be able to connect it to a phone using an adapter, but I'm not sure if it would work. It's really designed for PC/laptop use. I tried to use my laptops bluetooth, but couldn't get it to find the mouse, so I believe it only works with the dongle.

**Q: Do you have to use the transmitter for a wireless connection or can you connect directly with bluetooth?**
A: There are two versions, only one of the versions can connect by way of Bluetooth and the supplied dongle
This particular (M-RT1DRBK) does NOT have Bluetooth. Only M-RT1BRBK claims to have.
I purchased (M-RT1DRBK) and it only lasted 2 months, before it all of a sudden stopped working..

**Q: Is this suitable for child-sized hands?**
A: Having been IT lead in primary schools, I would think it a little bulky for an under 8, but otherwise fine, just need to get used to positioning thumb over the red cursor movement ball and index over front trigger.  Hope that helps.  (It works really well and I've found it a boon!)

**Q: If you lower your arm, will the ball fall off?**
A: No. It is a little loose and has fallen out a couple of times when I've dropped the mouse, but realistically it won't fall out in normal use or if you place it down. Even upside down you would have to shake it or knock it significantly to get it to come out. There is a hole in the battery compartment for pushing it out. I have to say I love this mouse it is very good. My only criticism is that if you are using this for portability it needs a case or small bag to transport it to protect it and keep it clean and in case the trackball falls out.

### ⭐⭐⭐⭐⭐ Carpal, cubital, and radial tunnel relief. Plus, this thing just works.
*by K***O on 20 August 2023*

I was pressing my thumb on the right side of the wheel unconsciously, and found that eventually this pushed the wheel towards the left, causing some accidental clicks of the left arrow "<" button. Part of the issue is that I programmed the down-press on the wheel as "Command," and instead of pressing straight down. I was pressing at an angle. Once I noticed this issue I just gently slid the wheel back into place and it worked fine. It is not fragile, I was really putting too much pressure on it. Issue #2: After turning the mouse off and then back on, sometimes the key functions revert to the default. I custom programmed the left-arrow "<" and right-arrow ">" as left-click and right-click, respectively, because I have no use for the "back" and "forward" web browser functions that are the default. I also reprogrammed all of the media player buttons to more useful actions (e.g. Copy, Paste, Undo, Redo, and Tab). For the most part, the custom-programmed buttons all function as expected.

My only gripes would be that the roller ball isn't terribly smooth. 90% of the time it's fine but there's a small area which seems to judder when you're on it and it makes it difficult to click specific spaces, which is often what I need to do. As others have said it does feels a bit loose and that may be part of the problem but it certainy isn't falling out. I'm assuming it must come out somehow to be cleaned but I havn't gotten far enough to figuring that out yet. The build quality is actually pretty good over all, I would not confuse how lightweight it is with it being cheap or poor quality at all. The left and right buttons either side of the scroll wheel do need to be pressed in the middle or lower down rather than where my thumb naturally sits nearer the top of the button but I think this is a design flaw rather than a cheap build - it is intentionally not "clickable" at the top, because that's where the pivot is. It also wouldn't be an issue if I had slightly bigger hands or longer fingers. My hands are very small so it does make it a little difficult to reach the buttons right on the bottom but it's not a deal breaker at all and those click perfectly well. I have quite a large screen too and a second screen next to it so it has been a bit tricky to get the dpi I need in order to move around the large area and also do the more detailed things in smaller precise spaces. I'm going to assign the dpi to another button so I can more easily switch dpi while holding in my left hand and see if that makes it better. I had a similar issue with the Logitech MX Ergo S which I ultimately found a good middle ground for without the need to be switching all the time but ultimately had to send back because the tilt of the mouse wasn't enough, I still had a lot of pain in my right hand and it wasn't able to be used left handed. It does feel a little bit expensive, especially as the Logitech mouse I mentioned above was around £80 and did feel a lot nicer with the roller ball, which let's be honest is the main function of the mouse, to move around the screen. Even though the quality is good and the program it comes with is great. There was a review saying it was required but I'm pretty sure you don't actually need to use it either. I don't know why you wouldn't use it though because it's great and gives so much more functionality. I'm not sure if this will replace my drawing tablet which I've been using as a mouse for over a decade, and would still be using if I could do it left handed, but at the moment I'm likely to keep it and switch between the drawing pad, normal mouse and this, depending on what I'm doing at the time, and so my right hand and wrist can have a break more often.

### ⭐⭐⭐ Great device when using your TV as a monitor
*by C***F on 3 November 2025*

I really enjoy this device as a change from previously using my Steam Controller for mouse input whilst using my TV as an external monitor for Windows 11. However, I can never seem to get keyboard buttons to map to the middle wheel successfully, and there are a couple of other quirks (when not totally flat, the ball feels a bit loose and rattles around slightly). However, the functionality is generally great, and my hand doesn't cramp up anymore compared with the prior setup. Also, the battery life seems really good so far. If the ball was more secure and the button mapping worked with keyboard inputs, I'd give it five stars. It is slightly expensive for what it is as well, worth bearing in mind. However, there's not many options for comparable products on the market. Update: took off a star, as the cursor does 'jump' fairly often leading to mis-clicks. It's not frequent enough to be a massive pain, but common enough to be an annoyance. When you are working with multiple tabs open and it jumps to close the browser, it's maddening.
