ELECOM Relacon Handheld Trackball Pointer, Ergonomic Thumb Mouse for Right or Left Hand, Bluetooth, 10 Buttons for TV, Presentation, Game, PC & MAC

When I read the other reviews, I worried that the ball might fall out when you turn it upside down, but no, it is not like that. I set this thing on the table on its side without the cradle and I have no problems. What people are talking about is if you drop this, then maybe the ball will pop out like the Logitech (and every other brand's) trackballs do. I don't know, because I like this too much to let myself drop it. Before going any further, let me stop and just say that I love this mouse. I have only had it a couple of days, and it is about as quirky as I am, but this mouse is really and trully everything I had hoped it would be. First, keep looking back at the price, which is amazingly affordable. Second, take a look around and the nearest similar device is a bulky version with a finger loop hole and basically everything to signal that it is for videogaming and not for the office. By contrast, this is like the classiest possible way to control your laptop during a presentation. If you had this, connected to a Macbook, controlling Powerpoint, people would assume it is some hot new tech they never heard of, rather than an actual obscure company with an idea that is bold and forward-thinking. That is if they even notice it, being so compact and discreet. For anyone with limited mobility, this could be a really enabling device on a whole other level. The quiriest detail is also it's coolest feature once you master it, and that is the variable speed control beside the "on" switch. I never knew there would be such benefit to changing my mouse speed conveniently. This will be the key to enabling maximum mobility with this mouse. There is one small drawback. I have medium-sized hands, so there is one motion that requires two hands, which is to move from side to side. You have to push down the scroll wheel and then roll the ball. That is the only feature I found here that requires two hands, excluding the moves that require that I hit shift on the keyboard before a mouse move. However, if you are planning to work with this thing up to an hour strait, then you should anticipate switching hands or fingers to keep from getting a cramp. When I do switch hands and fingers, I am able to manage and not cause that type of cramping. Doing this also helps you to find the most relaxed sort of default ways to hold this. One way is if you slide your hand back, so that your first and second fingers are only at the very edge of each trigger button, then that promotes a hand position that is curled at an angle very close to the natural resting postion of your hand. One final considerataion is that your success with this mouse will be linked to the task you most hope it will benefit. I got this almost entirely for graphic design, because the mousepad on my Macbook is not working ideally for my workflow, and the stylus-type pads are for drawing more than for designing. With most devices, the challenge is threefold. First, it is very easy to summon the left click on the Macbook trackpad, to the extent that it is so annoying and constantly in my way that I forget it's also a quick access to certain features. With this mouse, I am suddly actually using that left click and noticing it's options and benefits. Secondly, when I pull my finger off the Macbook trackpad, my cursor position is subject to a slight jump. That is a problem in precision graphics, and even the Wacom tablet or IPad with the Apple Pencil are not safe from this hiccup without a fair amount of finesse. This mouse solves that problem the second you get your ideal mouse speed calibrated, and get oriented to the device. The weight of the ball means the cursor absolutely only wiggles when you touch the trackball. This is the precision I needed. I can get used to the muscle memory of pressing the trackball to make it zoom in/out, and the two handed side-to-side movement is not too bad once I got in the habit of switching hands. Why would you want to switch hands, you ask? Well, welcome to your new reality, because you don't have to be ambidextrous to use this mouse with either hand. That is another reason I feel this would be a really great and affordable solution for enabling people who may have limited mobility. If you don't end up liking this mouse, it could only be because of a very limited number of reasons. Maybe you want to use this for many hours a day without changing up your grip or which hand you use, then this may not be the most comfortable mouse, unless you learn how to master that looser grip that I explained earlier. Another of the limited reasons you might not like this may be because of the size. This is probably most ideal for small-ish hands and least ideal for really large hands. My average-sized hands are maybe a small bit larger than what is ideal for this. Really, the bottom line is that if you are a person who wants to hold your mouse in your hand, not working it on the desktop, then I am convinced that this is the model to get, especially if you want it to be discreet. But that is why this seems like such an ideal mouse for giving a presentation, because it is nice and small in your hand and not like the handle-bar look it would have if it was the most ideal comfort for a large hand. Some reviewers commented on this mouse, feeling that it was too light and not sturdy. Well, think of this as a mouse, because this is a...well, a mouse. It is equal in durability to the average mouse you have seen. This is not a piece of sporting equipment like a Wii controller that offers a rubber cover because it expects betting mistakenly tossed. Please do not toss this mouse. This is a tool that is sleek and designed for a professional who wants to whip their cursor around their monitor screen with an impressive sense of command and agility. This is my ultimate mouse. Oh yeah, and the button to calibrate the speed is what you hold down to get the mouse to sync with your other gear. This can confuse you when you return to your Bluetooth menu on your laptop and click the old icon, which takes you nowhere. Again, hold down that calibration button beside the power switch on this mouse, and it will pop up in your menu as a new Bluetooth option. There are so many amazingly well-thought-out features in this device. A feature that I really love and did not expect, is that I can control my music on iTunes or Spotify in the background, while I am designing on Affinity software, without having to summon the player window to appear in front of my graphic window. The circular play controls function independently of which app window is in front. I mean...wow...really and truly, this thing checks every box I could have hoped for. We should be grateful they did not make this thing heavy for no reason, or three times this cost for no reason. This is simply a great product for a great price. I am thrilled with this purchase! Put the batteries in it and the weight is perfect!

This mouse does deliver what it promises, but barely. The build quality is REALLY cheap. Everything feels loose and on the verge of falling apart. I have only had it a few days and it hasn’t crumbled yet but I fear it will. With that said, it does deliver on function. There is a bit of a learning curve when switching from trackpads or normal mice, but it works. You really have to slow cursor speed down in software and use the lowest setting on the mouse itself. I can’t imagine using it cranked up. The cursor is just too unstable. The main trick is detail movements which I found to work best when applying some pressure to the trackball. However, if you switch back to a regular mouse on the fly you need to readjust all your mouse settings in the OS or your traditional mouse will be unusable. The one handed feature is great when using at glasses on the go. It connected to my ROG Ally no problem and the customization worked great with different layouts available for different uses. It really is the only item in its class. The cheaper one with the green ball doesn’t have the buttons and they are one of the best features for AR applications. I would love to see a mark II with quality improvements.

I switched to using a thumb trackball mouse from a logical technology company years ago. I was happy with it until recently when wrist aches made me turn back to the idea of a handheld trackball mouse. Previously I had tried a couple different units that featured a tiny, green trackball. Both units felt like junk and operated even worse. This time I was specifically looking for a bluetooth handheld trackball mouse so I didn't need a dongle tying up a USB slot on my laptop all the time. This Elecom unit turned out to be precisely what I was looking for. I am delighted with the functionality and features. The build quality feels on par with any logical technology trackball mouse and the performance merits the price. Initial setup was easy enough (despite foreign language instructions) and now when I turn it on, it connects to my laptop almost instantly. I'm happy with all the default button functions. I have smaller hands and find the device comfortable and easy to use. The tracking is spot on and I've been able to use it for work and play without issue. This mouse has several more buttons than I had before and I'm finding them all quite useful. I like that it uses AAA batteries as opposed to a built-in rechargeable. I'd rather swap out a couple batteries every 8 months than have to plug it in and wait. Not to mention I can pull the batteries for long term storage, if necessary. Also, those rechargeable batteries can only charge so many times before they fail, and good luck finding a replacement when it does. Alkalines for the win! Same goes for gasoline... But I digress. It's a great mouse, it's got a lot of features, seems of adequate quality, and is well worth the asking price. I read a complaint about the ball moving when the mouse is tilted to the side. I notice the slight movement as mentioned, but it has no impact on performance and I can use the mouse at almost any angle my hand can hold it without a problem. Holding it upside down, the ball will rise slightly before functioning as normal, but why on earth would you hold it upside down? Also worthy of note is that I can have the mouse and my headphones both connected to my laptop simultaneously without any issues. I cannot connect both my headphones and a bluetooth gamepad at the same time without problems, so I was concerned about that when I ordered this mouse.

This is my first foray into the world of trackball mice. Ive had this now for about 20 days. As a pc gamer and someone who uses their pc also as a home theater pc, with my 15+ years of experience with tech, I must say, Im very glad I decided to try out this method of cursor control. Most of my time on a compooter is spent lying in bed where using a traditional mouse just isnt as conducive to comfort and ergonomics. Its great not having to have a flat smooth surface in order for it to function properly. I love the fact that theres dedicated media controls that my pc automatically recognizes them as such. My gaming background includes LOTS of controller time so using my thumb to move the cursor comes naturally as if I was using a joystick. +overall design is great. very ergonomic and makes for a lot less strain and fatigue on the hand +dedicated media controls are a big plus + i dno what it is about the trackball but it looks cool as heck and after a good application of oil from my face(google it lol) and a little break in period it is now very smooth and I can get pretty precise with it if i have to. + theres a program for it you can download that lets you assign different functions for keys and a few other options like "flying scrolling" that allows you to automatically continuously scroll up or down by quickly scrolling up or down. works good. + some people seem to not like the stand that it came with but i love it. yes, the mouse just rests on it and its not secured to it by any means, but for me thats preferred as I can quickly snatch it up and put it back without having to fuss. im also not constantly bumping into where its placed so its not constantly falling off - not usbc rechargeable - if you buy the bluetooth model theres only bluetooth and no usb receiver for 2.4ghz like a lot of wireless mice have. itd be nice to be able to choose depending on circumstance. i prefer 2.4 as theres better connection and i only use it on a pc and not a tablet or phone. -trackball doesnt like staying in place and must be used in a upright position in order for it to work smoothly. if you hold it in your hand sideways the trackball has room to play and shifts a bit out of its hole. you can hold it upside down and it wont slip out but it does shift a bit. i understand there might be a design limitation here but itd be nice to be able to hold it in any position without the trackball somewhat slipping out of its slot a bit. - the scroll wheel does not make smooth complete rotations on the upward scroll. i actually returned the first one i bought because i thought it was defective but the second one is the same. as youre scrolling the wheel up you come to a point of mushy resistance that takes about two thumb scrolls to pass through, then it gets easier for a couple scrolls, and then then the resistance comes back. Ive never experienced this on a mouse before. I really wish this thing had a QUALITY scroll wheel, as it's one of the most used features for me. maybe one of those magic magnet scroll wheels like logitechs mastr mx has. this is not to say its bad, just wish it didnt do that mushy stuff upwards. - the scroll wheel button is starting to not register clicks as easy. having to push harder now - scroll wheel itself does not have side clicks where you can shift the wheel to the side and itll register input. what they did was include a button on each side of it that the computer registers as side clicks. works, but if the scroll wheel had the side clicks those two side buttons could be used for something else. Overall Im very glad with this purchase and would buy again. The design has room for improvements, and itd be nice to see some of the bigger names offer a product like this. The price seems a bit high but without any other quality options on the market its kind of to be expected. Update 08/27/2024 - welp, i kinda figured this would happen based on the reviews. it died last night. the button on the right of the scroll started sticking and becoming hard to actuate. the scroll wheel had been getting screwy. i would scroll but it would do a scroll back up, meaning i would scroll and stay in the same place. noticed last night that the scroll wheel had become off center. once i corrected that it started scrolling right and the button to the right of it became easier to use. but then the buttons just stoppped working. it connects to bluetooth but none of the buttons work. ive never encountered this on a bt input device before. it makes me feel like some of these are programmed to die after a certain time so ppl keep having to replace it. companies have been caught doing this kind of thing before. ended up ordering the non bluetooth version. lets see if that one fairs any better. i bought the bt version thinking I could use it on my laptop as well but i only used it a couple times like that since i bought it. if the non bt version does it too then i can almost guarantee this company has its products programmed to fail for profit. which would really suck because this thing is almost perfect. my only complaint is the build quality.

I own a few Elecom wireless track ball mouse before. The performance and feature on those mouse work really good. For that reason I bought the handheld version. But I can’t say it held up to my expectations. The feature on the mouse is ok, but not great. The performance is where they drop the ball. I try this unit on a few system to see if it was the computer or the Elecom. Each time it was the Elecom. The connection failed after a few min, the trackball would skip and not follow the movement accurate, also after walking away few feet from the computer is was connected to, it gave more connection issue, and this should be for a wireless presentation device. The trackball was not the most smoothes thing giving it’s a trackball and need to roll good. Over all I think this is one of Elecom worse devices. Maybe if they kept the 2.4hz connection it would response better

Used for 2 years now, have dropped it plenty of times, the ball has come out multiple times, but there are no visible marks or damages to it, it still works great, and it is always extremely comfortable. Will be buying a second eventually in case my first ever poops out because I can not see any using any other mouse anymore. Seriously ergonomic since you can use your mouse in your lap and does not demand you rest your hand/wrist on a desk. This is even better than the upright, Shark-fin mice. It does the job during games but definitely takes some getting used to. The biggest complaint is the DPI buttons location, which tends to accidentally get pressed. An inconvenience. The other button placements, like right and left click, are extremely intuitive and comfortable. Overall, takes getting used to, but once you do, this is the ultimate mouse for ergonomics on your arms.

The functionality itself is fine but the problem is the hardware. The ball inside the mouse is not secured down and even holding it dead level causes the ball to jump around while rotating it which leads to the cursor jumping around on screen. It has good ergonomics this is inherently the shape that Playstation and Nintendo Wii use for controllers so it's following a common form factor that's widely approved of. I also did not notice any lag the response time was good but this didn't matter because the accuracy was terrible. I disagree with the summary that said this was good for gaming the accuracy is terrible as I can't imagine trying to click on things in a game with this or trying to aim, that sounds like a special challenge to give to game streamers but not ordinary people who want to enjoy games. The price is also unreasonable for the cheapness of the product. $60 U.S. for cheap plastic, a few sensors, and a circuit board that talks to bluetooth should be under $15, these are very common parts purchased for a few cents each and low labor effort to assemble.

I'm liking it. I've tried the other handheld trackball mice found here on Amazon (if you've been on this search for awhile, you know the ones. There are two cheap white-label/generic models, one with a green trackball, one with a red trackball, both of which can be found with the names of multiple different companies slapped on them, and sold for wildly varying different prices. Those are both terrible, in too many ways to list here.) This mouse, on the other hand, is much higher quality. The trackball is smooth and responsive, the buttons are all well-placed, and equally responsive, but I've not been accidently pushing buttons I don't mean to, so they're just right. The ergonomics are pretty good. It is taking some getting used to holding it so that my middle finger is resting on the (default) left-click button and my index finger on the (default) right-click button, but as I'm learning to relax my grip and hold it lightly, it's starting to feel more natural. And the design makes it easy to drag things while holding either the left or right mouse button (yes, there are right-click drag functions in Windows.) I find myself wishing for slightly more granular DPI option than the three included, but perhaps I'll eventually adjust. The lowest feels too slow, the middle setting is just a wee bit too responsive for my tastes, and the fastest setting is just way too touchy (even on my 38" monitor), but some people like it that way. The only thing I don't like isn't about the mouse itself. The little stand that comes with it is worse than no stand at all. The slightest accidental nudge will knock it from the stand, and when that happens, the stand acts as a little slide, which sends accelerates toward the front edge of the desk far faster than most people could react to catch it. Luckily, the mouse seems tough. It fell to the floor 3 times before I gave up on the stand. The trackball popped out, and twice the battery cover popped off, but after putting it back together, it seems completely unfazed by the impacts. The localization (language options) in the app for it is very sloppy and unfinished. Once you've figured out how to flip it to you language of choice, several things are left untranslated, still showing kanji (Japanese.) Luckily the vital stuff you need to use is all translated though (or at least for the things I've tried so far. Not a reason to skip it though, it just stands out since the quality of the mouse itself is so high. I traded in my PC gaming addiction for learning to play guitar a few years ago, so I can't comment on how it works for gaming, but I can say it's not the first type of mouse I would reach for if I wanted to be pwning n00bs. But if you're looking for ergonomics as the most important feature in a mouse, gaming is probably not your primary focus anyway.
