Elecom Relacon Handheld Trackball Mouse, Thumb Control, 2.4GHz Wireless, Ergonomic Design, 10-Button Function, Windows11, MacOS (M-RT1DRBK)

As I have rheumatoid arthritis my hands, especially my right one, are largely useless, so using a conventional mouse, or even a standard trackball is now impossible. My right hand is constricted into a claw, with no finger movement and minimal thumb movement, so finding an adequate substitute has been both very expensive and difficult; *all* specialised input devices designed for the disabled are prohibitively expensive, usually starting at £150 plus. Enter the Elecom Relacon Handheld Trackball Mouse, which has *all* buttons - and wheel - customisable via the supplied software. With this rodent, I can control everything with my thumb, and don't have to worry about moving it around on a mousepad as, like other trackballs, the ball controls all movement. And best of all, it has a scroll wheel, which most adaptive trackballs simply don't have. Now I can play my favourite games again, with no loss of either speed or range of movement, not to mention being happily able to scroll down web pages with no difficulty at all. It also has variable DPI settings, again thumb controlled, so I can set it to best suit whatever I'm doing. And best of all, it's *much* cheaper than any of the "designed for disability" options around. So, if you have limited hand movement, or just want a more comfortable and ergonomic rodent, I can honestly recommend this one.

I hacve been waiting for this for years. I don't understand why this type of pointing device is not more common. The only others like this are cheap chinese things that break quickly. I tried two of them and they both broke within months. This is on another level of quality altogether, but it is a little pricey. It does have the same issue like the cheaper stuff though, which is that the ball is not kept in place snugly and if you rotate your wrist or otherwise move your arm away from the horizontal, the ball tends to shift from its proper position. There should be some kind of ring to keep the ball in place. As a result, clicking and scrolling takes some practice but the trackball is very smooth and works very well. So this is great for couch surfing or standing, any situation where you're not sat on a desk in front of a keyboard but not much good for anything other than basic browsing. The ball is also too small for precision work, and index finger operated trackballs are more ergonomic IMO. Otherwise this has the usual Elecom high quality and it is super nice to be able to browse without being tethered to a desk!

Works really well for my use case of using it as input to android TV for apps that want mouse input. Comfortable, good battery life, precise. Edit to update that I paid £50 for this in 2020, these prices in 2023 are scalper prices and it is not worth £90/£100 at all. Not even close.

The Relacon does what i bought it for, that being to relieve the stress on my arm making it hurt. My arm is indeed feeling better. But i feel the price is not reflected in the quality of the product although looking at the alternatives on amazon and elsewhere this is probably as good as it gets. The biggest problem is that when i start my computer and the relacon dongle is in the computer wont recognize any clicks from the relacon or any of my other mice. I have to restart the computer once or twice and then it works. This is not great, ive never in all my years with different mice had this problem, sure if it was just the relacon but as it will stop button clicks from any mouse. I can live with it but i dont feel great about paying as much as i did for it and considering you can get a top notch mouse with very good quality from other mouse brands for the same price this is disappointing to say the least and with the other quality issues its definitely not worth the prize. The DPI button, The relacon is ambidextrous, but somehow they forgot that the DPI button is on the left side, this means that if you are using it left handed you cant use that button as its against your palm, luckily that doesnt seem to mean that the button is pressed inadvertently so thats good. On the other hand while im using it right handed i now and then manage to hit the button, which is annoying. It needs to be a little stiffer to avoid unwanted button presses and it also needs some kind of texture so you can feel that your finger is on it as its completely smooth and blends into the surface of the mouse so much so that when i actually want to press it i cant find it with my thumb. Trackball and the tracking is good no problems there and no stuttering or the ball sticking to the pins because it has bearings, awesome. I tried a kensington trackball and it was useless when it came to doing small adjustments because it would stick to the pins it used instead of bearings. Be aware that while you can use it having your arm straight down the ball will fall a little bit out of the socket and while it will still track, everytime you release the ball it will change position making the mouse pointer jump but if you adjust how you hold it so that the Relacon is horizontal in your hand you can still use it, some buttons will be awkward to push but its fine. Software, it allows you to reprogram button and move some sliders around, i didnt use any of that and the one thing i wanted, to be able to set DPI and to set the different DPI levels for the DPI button is not possible to set with it :( Size is ok, i wish it was a bit tiny bit bigger but it feels fine, after long and intense use my hand can get a bit stiff, no worries just switch it over to the other hand. Weight is fine, you feel it in your hand but long use wont tire your arm out. Buttons; the right click is too easy to push, much easier than the left click button and it leads to some inadvertent right clicks now and then. Right and left click are otherwise nicely clicky but a little rattly. The other buttons are fine except for the DPI button which i talked about above. Scroll wheel, works fine. For some reason if you push it from the left it will click but if you push it from the right side it wont click it will slide a little to the left, still works the same and you can push it back but i've never had a scroll wheel where i could push it along the axis. Battery, 2 AA batteries, easy to install. I've had it a week and so far so good. Sadly the battery lid comes off too easily as when i grip the relacon tightly the battery lid will come lose. Not a problem, there is really no need to grip it tightly but wtf it shouldt come off just by squeezing it. Dont get me wrong it sits just fine in place and isnt a problem until you actually squeeze it hard. All in i would return it but as the trackball is very good and it helps with my arm i use it whenever i don't need to use a regular mouse(more intense gaming and some work where you have to click on small things rather quickly). Its good i use it a lot but the flaws and the prize are too muchfor anything more than 3 stars.

Putting aside that this took ages to arrive because it is an obviously Asian product sent from America... it is, to put it lightly, disappointing. The trackball rattles loosely in its casing which also harms the precision of cursor movement, the construction itself looks and feels cheap and shoddy, the "left" and "right" buttons are obviously wrong way around (regardless of which hand you use, you're left-clicking with your middle finger), and the mount seems to serve no purpose whatsoever. Basically I'm expecting it to break down and stop working in the next week or so. [Update] Three more things worth noting: Firstly I downloaded the official software to try and switch back the first and second buttons, only to find it was in poorly programmed Engrish and didn't even warn me before forcibly rebooting my computer, and the program itself left an unwanted icon on the screen until I force closed it and ordered the computer NOT to restart it. Secondly, the trackball cuts out when the device is held at certain angles, and doesn't work at all at other angles, which rather defeats the purpose of it being handheld. Plus the cursor will skip when the thumb is removed from the trackball due to the ball falling back into a neutral position. Thirdly, the power switch is stiff and it can't be easily switched off without clawing at it and applying a lot of force... which ruined my attempt to use the power switch to stop the cursor skipping when I remove my thumb from the trackball. [Update 2]: It fell on the floor (on a rug) once. The ball fell out. It lasted less than a week.

Love this mouse. Wouldn't go back.

Quite expensive item that took a week to deliver and after installing the software discovered that right click button was defective. Then have to post back at my own expense. Take care if considering purchasing

This item was delivered: 20 Jul 2020 and by September 2020 it stopped working! ( BROKEN ). I contacted the seller and asked if they could send me a replacement receiver (as the controller part still lights up) and I was still happy to pay for the replacement. They refused to do this, so now I'm down £50.00. I was unable to return the item due to illness, I explained this but it made no difference to them, not very helpful.

Le prix vaut le coup pratique à utiliser et il fonctionne bien avec un adaptateur USB sur un smartphone Android

I really like this mouse in a lot of ways, but there are other times when I've struggled with it, and I've ended up not using it as my daily mouse (I keep it on hand in case my daily mouse dies, like my Logitech finally did). I could see it being great for specific situations (like the listing that shows using it with a laptop at a non-desk location, using as a media controller, etc) but as my everyday mouse at my desk it just didn't work out. I've been using a trackball super happily for about 5 years, so all of the pros and cons below I'm approaching as already being a trackball user. (If you're not already a trackball user... hang in there. Once you get used to it it's GREAT.) PROS ------ - Can hold it in really any position, and it doesn't have to be up on your desktop. I just held it down in my lap a lot, or next to my side when I'm using a standing desk, but you can also rest your hand on the edge of the desk in different positions too. Even set your hand on a luxurious pillow if you want. :D - It's ambidextrous, so it works great for righties and lefties. I'm not ambidextrous myself at all, but if my right wrist is really bothering me I can switch to my left hand; it slows me down a little, but I'm still perfectly able to keep doing what I was doing. - Super flexible in that it allows you to hold it basically however you want. I wish I could adjust the curve of the underside (like have the finger groove hold my other fingers further back) but I don't know how you'd possibly make that adjustable), but just being able to not have your wrist on a desk is a pretty big deal by itself. I've had a lot of wrist pain over the years and this DEFINITELY helps. - Programmable buttons are nice! I don't need them mostly and even the ones I would use (like the back and forward web browsing buttons) I just forget they exist, but if I used it for a long time I'm sure I'd eventually make use of them. It also has a tilting scroll wheel... I had to look up what that even was for, but turns out it's for scrolling horizontally. The more you know! :D I never used it, but it's often just nice to have more options rather than less with anything. - The driver/controller program for it lets you set which button does what, and things like your scroll speed and how to make the wheel do a speed-scroll, plus there's a DPI controller on the mouse itself. CONS ------- - Switching between mousing and typing is just prohibitively annoying. Because it's not on the desktop, every time you want to type two-handed you have to either put the mouse completely down or set it on its stand. And if you're holding down in your lap like I do it you're reaching up and down a ton (which to be fair you'd be doing to reach the keyboard anyway). I just wound up doing a lot of hunt-and-peck typing with my left hand only, which made me remarkably slow at what I was doing compared to what I was doing with my previous trackball. - The stand is basically there to hold the mouse when not in use, but it's a little bit precarious. If you set the mouse down carelessly, it might slide off. I've knocked it off by jostling my desk. My cat's knocked it off. (Why is my cat on my desk? I'd also like to know this!) I'm working in a room with carpeted floor so it hasn't been a serious problem, but if I was using this in my previous workplace with concrete floors, it'd be extremely broken by now. This issue AND the problem mentioned above could be solved by a more substantial base where you could set it (and it would stay) that could turn it temporarily but SECURELY into a desktop mouse. If the stand allowed you to more easily actually USE the mouse while it's set there, it'd become like 90% easier to work with it when you also have to type. - Precision work (like for instance trying to draw or erase an area in Photoshop) was surprisingly difficult. I'm not sure why; I've been doing that work with a trackball mouse for years, so maybe this one's just a bit more sensitive or the ball's a little looser? I really had a hard time producing any sort of non-wobbly line, and no amount of fine-tuning the speed or DPI or anything really helped. - It's a little small, so if you have huge mitts it might be too little for you. For reference, I typically wear a medium in latex/nitrile gloves, and a large in outdoor type gloves, and it fits my hand pretty great. I think smaller hands would probably be fine also, I just think it might be uncomfortable for folks with really big hands. - If you need to get the trackball out to try to clean out gunk, it's surprisingly hard to get it out. It is surprisingly EASY to get it out however if it's knocked on the floor. - I really needed this to have a storage space for the USB dongle, like my old Logitech did. That one you could store the dongle inside the battery compartment; this one's a little weirder shaped but it has an entire base that could have had, if not a screw-top compartment or something, a little slot built into it. I don't think it's terribly overpriced or anything for what it is, but an upgrade on the stand design would make it so much better. In summary, it's a good mouse and if you've got problems with your wrist and don't need to switch constantly between mousing and typing, it's worth a try. For me after about four days of trying I've switched away to another type of ergo desktop model (wish me luck lol) but I'll have it on hand if I need it. Possibly all bagged so I don't lose any components. :D

2 years now and I love this mouse. This mouse is perfect for the couch surfer, you can set up a pc TV connection and do all your activities in blissfull comfort. Whether it's streaming, websurfing, video editing, gaming, or anything else, this thing is sidekick. In fact, I think it could be the ultimate gaming mouse with a few tweaks and Im suprised there are so few similar options on the market. I would suggest this company design a second product from this, and adjust some functions for improved accessibility. The trigger buttons for example, they are not easy to have both covered for long periods, the ergonomics of the button placement is not ideal. One finger is fine, so 95% off ehat you do, you will not have a complaint with this, but in game it's almost a game breaker. You need to have both index and middle finger naturally positioned on buttons for proper gameplay. Next, rethink the middle mouse button. Alot of times in a game you need to hold the middle mouse button while moving the mouse, and this controller makes that a two handed or awkwardly painful process. Not The controller would. Benefit greatly from a grip button function, so this could be explored. And finally, improve the ball design. It's pretty good, but it's loose in the well and jiggles or moves as you move your hand. This creates mouse pointer instability. Put a lock on collar around the top with replaceable felt liners to firm up that feel to smooth AF. And add some buttons along the side for the thumbs. And give it a belt clip for the wrist strap. It needs to hang from the waist line with a short lead so you can walk around with it and drop it freely. I'm going to 3d print one, but it would just be a tiny little thing to include and it would go a long way. Those few things will take this thing to be the ultimate living room, home theater, gaming, or conference companion. Seriously. I had the surface mouses and the the surface rested trackball mouses. This thing is superior anywhere other than a desk. It's also tough. Dropped it probably well over 100 times now. Sometimes the ball goes flying, but it still works great and isn't damaged. And batteries last forever in it. Would suggest getting Bluetooth to reduce number of USB plug in devices, also because others report the the 2.4 ghz transmitter failing and they aren't standard channel transmitters either so you can't really replace them with a universal one. It would be incredible if they made both left and right handed versions, mirror imaged. Then users could buy two and then no keyboard game as well. And no, it's not the same as a xbox controller experience. I would pay $200CAD for each controller if it were available.
