Trackballs are really something you need to try yourself to know what you need or want. You may think you want certain aspects based on design or what should work best, but actual use experience will toss all that out the window. I tried all of the finger trackballs first because I was under the impression that it would be better ergonomics and accuracy. The Deft pro, kennsington expert, and slimblade (along with some other ones that I tried) had issues with the trackball sticking when trying to do micro/fine movements such as moving the cursor just a little bit to click on something. This made it extremely difficult to use on any screen set to high resolution and small text. Then I tried the Kennsington pro fit, which to my surprise, I had mich better control over the fine movements than finger trackballs. I thought the vertical position would make it more ergonomic, but I found it uncomfortable to use. That model also got dirty really fast, to the point that I had to clean it every hour. Not sure why. Then I tried the EX-G pro, and it is better than the $150 CST L-Trac. The L-Trac was the best finger trackball, with great bearings that allow for fine movements and high quality buttons. However, the L-Trac had poor button and scroll wheel placement that ultimately made it very unergonimc to use and acutally caused pain for me. Now on to the EX-G Pro Pros: 1. Shape: I found the flat shape to be the most comfortable. I can easily reach all buttons, including the back and forward. 2. Wireless: It is not necessary for a trackball but great feature to have. 3. Replaceable batteries: No need to worry about charging and it won't become useless if the battery ever goes bad. 4. Lots of buttons: It has 2 additional funciton buttons you can bind to whatever you want along with the traditional buttons (left click, right click, middle click, back, forward,) and even scroll left and right on the mouse wheel. 5. Price: This has way more features than the MX Ergo but at about half the price. 6. Smooth bearings: The trackball moves with ease. This allows for fine movements (moving the cursor in small movements) 7. Easy to clean: You can just pop the trackball out from the bottom to clean. Most trackballs have this feature or doesn't need cleaning (CST L-Trac) though. 8. Ratcheting scroll wheel: This scroll feels pretty good. Not the best but above average. Cons: 1. No tilt adjustment: This doesn't matter to me as I find the flat profile very comfortable but others might disagree. 2. Micro USB connection: It really should be USB-C but I don't plan on using it. 3. Feels hollow: The texture feels pretty good but the mouse feels hollow when you pick it up and move it. 4. Somewhat easy to accidently hit function button to the right of right click. I have found myself accidentlaly hitting this a few times.

Elecom should be considered as a top-tie contender with the likes of its competitors, due to the fact that they can deliver on so much for a lot less money. I received this mouse the other day and with continued use, since that time, I found some solid pros and cons. First, the pros. The size has been increased, over the previous version, to deliver a much better comfort level to the hand, and with a more pronounced texturing to the upper surface, your experience using it is more comfortable. The button layout takes a bit getting used to, if you are coming from a previous generation or a different mouse altogether. Programming is easy with their software, lightweight and easy to manage, but there is a glaring con to this, I will touch on in a minute. The trackball placement is a bit more ergonomic that its predecessor, so overall, Elecom nailed down a solid format. As for the cons, two things: First, the scroll wheel is way too rigid, and doesn't deliver a smooth scroll experience. i suppose smaller hands and shorter fingers night yield a better experience, but for me, i have to contort my index finger back slightly to get the wheel to scroll, instead of registering a middle button click. Scrolling backward is easier and manageable, but overall, they need to tone down the rough scroll. Second, the trackball needs work, and this may not be so much a fault with Elecom, but after repeated use, the ball doesn't flow as good as it should, going from smooth to herky-jerky, due to oils from the skin transferring onto the ball. This isn't a deal breaker, and neither is the scroll wheel issue, but these are two things Elecom should concentrate on for a future revision. Connection choices are plenty with this mouse, from the traditional wired to bluetooth, your choice and it's all included. The selection of DPI settings is a plus for the gamers, coupled with the LO and HI signal switch make this a go to mouse and for a reasonable price, compared to their competitors.

I use trackballs exclusively. I'm a software engineer, so I use them a lot, and won't tolerate 'glitches'. I have largish hands. The most comfortable I've ever found was the (obsolete) Microsoft Trackball Optical D67-00001. That one is sluggish for gaming though. But I've used them for 10 years, work and home, have several, and I've never had one die. I've used the the Logitech trackball, but I always find it overly sensitive, and just enough too small that I end up shaking out my hands a few times a day. I always end up going back to the Microsoft. I have 3 each of the Elecom M-XT3DR (R handed wired) and M-XT4DR (L handed wireless). After waxing the balls (Renaissance microcrystalline wax polish) and putting a little Teflon lube on the ball contact points, they work fine. I've been using a set at work and at home for about a year now. No complaints, no issues. Comfoartable - I never notice any discomfort or difficulty. I decided to try the M-XPT1MRXBK, as reviewers compared it favorably with the Microsoft. Got one, and have been using it on my home system for 6 months. Briefly: - It looks and feels like higher build quality than the other Elecom trackballs I've used. After six months of daily use the palm area is slightly shiny, but otherwise you couldn't tell it wasn't new. This is the first trackball I can say is unequivocally an acceptable replacement for the Microsoft. - It's a little bigger than the M-XT3DR (which is virtually identical in size/shape to the Logictech). It doesn't really have a bigger footprint, but does have more volume. It was immediately more comfortable to my hand than the M-XT3DR. it's definitely a step up from the M-XT3DR. It's my new favorite. - The ball moves quite smoothly right out of the box. I used it for a month or so unchanged, but found the ball start motion just sticky enough to be annoying, making selecting a few letters out of small text frustrating and difficult. Finally I pulled the ball, and waxed it and lubed the bearings as above. That made a small but significant improment. Now I have no issues at all with the movement. It's been about 4 months since I did that and it's still fine. - Wireless seems to work okay. I keep having an issue where If I don't use the trackball for several seconds, it 'stalls' for about half a second when I move it. I frequently move very quickly between (many) windows, and I have focus-follows-mouse set (so I don't need to click on a different window to 'select' it). Also I often move over a new window (which almost instantly gets 'selected') and start typing. Very often the first character I type is 'lost' if it's been a few seconds since I used the trackball. Very Annoying. I can't say for sure this is the trackball. - Wired. This is how I use it most of the time. Works great, and the half-second 'stall' I see when I'm using wireless is NOT present when I go wired. Not sure yet about the lost character issue. - HOWEVER, the micro USB socket on the trackball is does not snugly grip the connector. You can move the connector back and forth about +/-10 degress while it''s plugged in. I tried a better cable, which changed nothing. It just feels loose, although the socket itself is firmly attached to the trackball. I pried the top and bottom sicde of the socket in a little, to make a tighter fit, which helped some, but it still fis not snug. Unfortunately, the connector is apparently loose enough in the socket that if you physically move the (entire) trackball, about half the time it will suddenly quit working. At first this would happen occasionally (about once an hour) even if I didn't touch the trackball. (I suspect just the jarring from typing did it). Very Annoying. If you wiggle the connector the red 'connected' light comes on briefly, but the trackball generally doesn't reconnect. Sometimes you'll see an error popup about an unrecognized USB device. Usually you need to disconnect the cable briefly, then reconnect it, and it recovers correctly. After I bent the top and bottom of the socket in slightly it's never happened without me physically moving the trackball, and even then only about half the time. This is Very Annoying - but since it's a trackball, I rarely physically move it. So I forget, and then when I do move it, half the time I have to do the disconnect/reconnect. Grr. - Bluetooth - never tried it. - L, M, R buttons: No issues, ever. Short throw, definitele click, no missed/multiple clicks from a single motion. - Scroll wheel: It has a detent, but it's fairly light. I thought it would be too light for me at first, but I've never had an issue. - Forward/back button work fine and are perfectly placed. - 'sensitivity adjust' switch works, and bumps the effective motion up/down ~30%. I like a very responsive trackball, so I leave it on 'high' always. - I have not tried to use the pinky finger or thumb buttons, so I can't speak to them. The pinky button is perfectly placed, and feels just like the R button. The thumb button hits my thumb just below the joint, so It would be awkward to use more than occasionally. it would probably be perfectly placed if you have small hands. I originally installed their software, but never changed anything. So eventually I just disabled it, and the trackball still works fine. Recommended. (But you will want to wax the ball and Teflon the bearings).

UPDATE: As of January 2023 I unfortunately have a different opinion of this trackball than I did initially. Things started breaking. First, the trackball stopped working in wired mode -- it would operate for a few seconds, and then just go dead. Then it started to intermittently drop out in Bluetooth mode. Then the battery contacts became loose. Then the rubber feet came off. Then the back and middle click switches wore out. Finally, the wireless connection started to drop out so much that I just gave up on it. All this started happening a while ago while I was within my 3-year warranty period, but I was never able to get any kind of response out of Elecom's support contacts and pretty much gave up. Still, I like the trackball enough that I'm almost tempted to buy another, but for almost $80 I don't want to run the risk of another one breaking in a couple of years. This is an excellent trackball that offers marked improvements over the previous generation Elecom trackballs and over popular options like the Logitech m570. The quality and engineering is better than average, and the extra buttons and connectivity options offer great versatility. I have only minor nitpicks and would rate it 4.5 stars if I could. My background: I have been using thumb-operated trackballs as my primary pointing devices since the late 1990s. The venerable Microsoft Trackball Optical cemented my status as a thumb trackball aficionado, and I have used just about every widely available thumb trackball that has come out since. I currently own and primarily use the ELECOM M-XT3URBK wired trackball and a fleet of Logitech Wireless Trackball M570 s. I do a lot of programming type work across 2 or 3 1080p monitors, and I play some FPS games, all with my thumb trackballs. This trackball just launched and currently ships with all Japanese packaging and documentation, but you can find the English documentation on Elecom's global website in the download section. The current packaging is a nicely printed box with a window flap displaying the trackball within and copious (Japanese) notes on the trackball's specifications and abilities. It generally takes Elecom a few months to make the English packaging available for a new product, so this might have changed by the time you order. The first thing that impressed me about this trackball was the smoothness of the ball movement right out of the box. Most trackballs have a "break in" period where the ball movement doesn't feel smooth, and previous Elecom trackballs with the gray ball in particular could actually have a really rough feeling to them out of the box. This one felt perfectly butter smooth from the moment I started playing with it. The supporting bearings for the ball seem to be the same as in previous Elecom designs, but the ball itself has far lower friction. The smoothness of the ball actually seems to contribute to it picking up less "hand gunk" as well, as I haven't found myself having to clean the bearings. For those who care about the "spin factor" of a trackball -- how long the ball will freely spin if you give it a good flick -- I will note that my unit has some spin, but not as much as a broken-in m570. Ergonomics are substantially different than the previous Elecom thumb balls. This model adopts a wider, flatter, slightly longer shape that allows my hand to rest in a somewhat more neutral position compared to the curled-palm grip of the Elecom M-XT3. Compared to the M-XT3, my pinky now rests on the right edge of the mouse instead of on my desk, and my wrist and heel of my hand are elevated slightly off the desk by the extended palm rest. Also, where the M-XT3 is sort of scooped out where the thenar eminence (the meaty "drumstick" of your thumb) sits, and the m570 has no support in this area at all, this M-XPT1 curves continuously across that area, which allows less stretching along the expanse between the wrist and thumb joint and relieves tension in that area. My wrist is rotated into a slightly more natural outward-turned resting position on this trackball compared to the other Elecom. It seems like it's a few degrees away from perfect, though -- I feel like it's slightly more comfortable to have the trackball raised on something so it's tilted outwards a little more. This mouse offers the same extra ring finger button as previous Elecom offerings, plus a new thumb button (just below the ball) and center button (just below the scroll wheel). This is one of the key features that makes this a great trackball for gaming -- it's really nice to have extra action buttons on the mouse for certain games. My gripe about the two new buttons is that they are in less useful positions than the ring finger button -- you need to move your thumb to the bottom of the ball to hit the button there, and the middle button under the scroll wheel is almost completely under your palm when you use the trackball so you just about need to take your whole hand off the thing unless you can awkwardly press it with the base of your middle finger. These buttons are nonfunctioning unless you have mapped them using the Elecom MouseAssistant software available for Windows and Mac. You need version 5.1.6 or better for this trackball, and there are links floating around out there to an older version that won't work, so be careful. There is currently no support for the extra function buttons at all in the Elecom drivers for Linux. Button action is nice, with a slightly firmer-feeling click than an Elecom M-XT3 or Logitech m570. I haven't noticed any missed or spurious clicks; the button functioning is perfectly solid in the couple of days I've had it, and experience dictates that I should expect a lot of use out of the durable OMRON switches. The ring finger button and thumb button (next to the trackball) might be a little bit light and are slightly too easy to depress accidentally. This model adds a DPI adjustment button on the bottom of the mouse, toggling between 3 preset resolutions. The decision to put this on the bottom of the trackball is questionable, as the common use case for a DPI adjustment button is to temporarily slow the mouse motion down while making a fine adjustment (e.g. some people use this for sniping in FPS games). On the bottom of the mouse, it's useless for that purpose, and the only thing that makes sense to me is to leave it on the highest DPI at all times and adjust mouse sensitivity through Windows. Interestingly, the Elecom M-XT1 model from several years ago had the ring finger button mapped to adjust DPI, but this feature was completely removed in later iterations when they made that button a remappable function button instead. This model supports wired connectivity with a supplied (rather cheap quality) Micro USB cable, or 2.4GHz connectivity through a supplied USB receiver, or Bluetooth. In wireless mode, the trackball is powered by 1 AA cell -- no rechargeable battery here unlike Elecom's Deft Pro finger trackball, which I actually consider a plus because a mouse with a non-replaceable built-in battery will be useless when the battery eventually wears out. Wireless performance seems fine on both Bluetooth and using the proprietary receiver. I was able to operate it in the same environment as a bunch of Logitech Unifying devices without apparent interference issues. Wireless range is satisfactory for operating with the receiver plugged in behind a desk several feet away. I haven't done formal testing on this, but I did think I actually noticed a very minor but noticeable input delay very rarely while using the trackball in wireless mode that was not noticeable in wired mode. Possibly placebo, but it feels a tiny bit different. The documentation does not clearly explain what the "L" and "H" modes on the power switch do, but I believe H mode uses a higher update rate for wireless connectivity so you can potentially realize smoother motion and quicker response vs. the battery-saving L setting. I was not able to notice a practical difference between these settings in normal use. [EDIT: After some more time with the mouse trying both settings, I realized I was noticing a difference after all, and I did some systematic testing. It turns out that H mode uses an update rate of 125Hz and L mode roughly 62.5Hz. In L mode the cursor may appear to skip during very fast movements, and L mode would probably not be good for playing games where you care about potentially experiencing one frame of input lag. The "high" rate of 125Hz is already considered fairly low compared to some gaming-oriented pointing devices on the market.] There are a few minor issues keeping this from being a perfect thumb trackball, all of which I've covered above -- imperfect placement of function buttons, the DPI switch being on the bottom, the documentation being in Japanese and the software being hard to find, lack of complete Linux support, and the tilt angle not being exactly perfect for me. Other than these minor issues, it's hard to find fault with it, and overall it feels like an upgrade over the Logitech and Elecom devices that I was already pretty satisfied with.

The Logitech MX Ergo is a very good Thumb ball with a very good warranty. This one is just that much better in every regard. More ergonomic and more precise. Dare I even say you could game with this. Almost all trackballs require registry hacks for speed, acceleration and breaking. This works out of the box on one of your preferred 3 settings. I suggest if you use it wired you get a good heavy duty USB cable. This is also built better than any other track ball in my opinion. I prefer thumb to palm or fore finger. Just a preference. Do not believe any articles stating they will cause thumb injury. They simply cannot because there is nearly no resistance on the ball. Plus you are barely moving your thumb. You use your thumb more everyday regardless. This rides on synthetic rubies and the optical sensor is tuned to their ball. Yet, the ball has "micro" indents. So it has per pixel accuracy. Personally it fits me like a glove. The tenting is just right for me. The Logitech is too little flat and too much inverted. This is also much better at keeping out gunk and easier to remove the ball when need be. Furthermore the ball is heavier for more inertia but breaks very accurately. I want everyone to be aware this has NO warranty outside of Japan! If you are a hard core user,coder plan to be buying 1 or 2 per year which is par for the course. There is a more expensive model of this on Amazon with one letter missing in the part number. Also be aware per Elcom's website it is the same exact model for the same Yen. Yes, it is made in Japan not China. I am not sure why there are duplicate models. Save your money. A different seller wants more money for the same thing. Since you will probably be replacing this frequently anyways unles you are capable of and wish to repair it. Then you could feasibly kep it in service a long time for low cost. It is just the switches that go and they are 40 cents each in low quantities from electronic parts suppliers. It is by no means low quality. It is just normal for any of these to last 6 months to a year at 14 hours of usage per day. I also like that it takes a standard battery. The highest real rating on a NIMH AA is 2800MAH. That will run for about 1.5 years in this! Logitech runs about 2-3 days and the battery is not replaceable. This is usually found for the equivalent of about $300USD in Japan, so here for $69 it is a very fine deal. I would equate this to Topre keyboards. If you are looking at this you are probably familiar with Topre as well. Same type of quality. I would not buy much into the bad reviews personally. There are alway's duds in which case you have 90 day's to return to Amazon. Or better yet purchase the inexpensive extended warranty it is going to offer you when you check out. It will probably be worth your while. One thing I do not understand is here on Amazon the picture states the switches are rated 100,000 clicks. Elcom's website says 10,000. They are indeed Omron switches which are in fact rated for 10,000 clicks but that is actually more than you might realize. In summary I will say that this is the best Thumb ball that I am aware of if you prefer to use a thumb ball. If you are a heavy user you should not be using a mouse due to repetitive motion injuries which are no joking matter. I personally prefer a Thumb ball to all other types of pointing devices but what suites me may not suit you. Elcom also makes a Forefinger model of this which is fine as well. Just make sure you get the "G-Pro" line from Elcom. That is top of the line. One last thing. It says it has 8 buttons. They do not count the tilt as Logitech does so in that case it has 11. As far as I am aware it has more buttons than any other track/thumb ball. There software does not provide for macros though. If you wish for that functionality you will require 3rd party mouse software which usually comes at a nominal cost In closing most certainly 5 stars from me. Could not be happier with this device.

I have been a user of traditional mice from Logitech and I thought that their software was bad enough. I tried to set up this trackball mouse for half an hour but I gave up. The software from Elecom is nowhere close to what Logitech offers: 1. It takes a full reboot to install/uninstall. Not a huge deal but definitely annoying when you are eager to try this out half way through your work. The restart prompt stays in the foreground, without a way to dismiss or ignore it temporarily. 2. The mediocre UI might as well be a Java app from 20 years ago. English text is not exactly natural or intuitive. I had to try the forward/back function to know that they work outside of Safari, because of the weird "(Safari)" after the name. 3. The range of customization is limited. My keyboard shortcut to call Mission Control is bound to Ctrl+Opt+Cmd+Shift+Tab, but there is absolutely no way to include 4 modifiers to a keyboard command. Yes, you can bind an arbitrary keyboard command to a button, but the allowed combination is limited to a pre-defined dropdown. I would expect the app to capture what I press instead of offering 2 dropdowns for different key combinations. 4. To apply any change in preference, you need to click Apply, and then the app quits automatically. Probably you don't need to tweak your preference often, but can you imagine the Music app quitting itself every time you want to skip a track? 5. The gesture feature is pointless and confusing. The UI when drawing a gesture seems to be constantly bugging and I don't enjoy the sudden flashes. With the software out of the way, a few general comments about other stuff: - Overall the quality of the mouse itself is ok. There are a few sharp edges which are unnecessary for a mouse. - The manual/guide inside the box was 100% Japanese. It does tell you how to put in the battery and explain the connection settings. - I felt some pain around my shoulder after briefly using it, but likely this is me not used to a trackball mouse.

I do like the size of this mouse. It's a tad larger than the M570 and fits a larger hand well. The software to go with the mouse takes a bit to find and I recommend getting the most recent software. The only thing I do not like about this mouse is it is almost impossible to use the scroll wheel without clicking the button in. I had to disable the scroll click function of the mouse because I found myself having to deal with it too much. One thing I do like about the scroll wheel is the left and right motion to actually scroll sideways. This mouse would be 10 times better if the scroll wheel button had a heavier switch or less detente on the scrolling function. I originally thought I might could find a use for these extra buttons and the only one I do not have disabled is the one behind the scroll wheel (which is impossible to accidentally press), which I use for volume muting/unmuting. The bluetooth connection to my Dell e7440 is not very good and highly choppy. I'm pretty sure it's because the dell is bluetooth v3 and not v4 as this mouse is (INCORRECT ASSUMPTION! READ BOTTOM OF REVIEW). Receiver works well. Wired mode works well (aside from resetting my programming every time I switch to wired mode and then back to receiver). I'm have decided to return this ELECOM after a week of testing it out so I can buy the MX Ergo, mainly for the fact that this mouse is impossible to scroll without pressing the scroll button. Your mileage may vary. I purchased this mouse as a refurbished model and it appears to be fully functional and came in a damaged box, but everything was included. I did notice on the last day of use the scroll wheel starting to squeal intermittently. Edit 12/10/19: I originally thought the crappy bluetooth connection was my laptop's fault but after connecting the MX Ergo via bluetooth, I can say that it is definitely not the laptop! If you want to use the ELECOM via bluetooth, consider that it may not work that great. Give it a shot if you're on a budget but I'd probably rather buy the M570 again and again until you can afford the ergo.

Good: 10 buttons (including tilting wheel). Three connection options (wired, Bluetooth, 2.4GHz USB dongle). RF switch allows usage between two different PCs. MouseAssistant5 software has a good interface with many options. Multiple DPI settings. I like the idea of a BT power/performance selection switch but I don't need it. Bad: Ball tends to lift and skip when moving rapidly left. Almost impossible to tilt the scroll wheel right without also middle-clicking. DPI switch on bottom is inconvenient. Wired connection disables both RF connections. RF switch is a slide switch and hard to move. Loss of connection (like switching the RF switch to a different PC) will cause MouseAssistant5 to immediately exit. Not rechargeable. Linux: No Linux version of MouseAssistant5. It seems to rely on a custom Windows device driver so while it can be started with Wine it can't connect to the trackball. But the basic default button functions work OotB and the xev utility does see all 12 (including wheel scrolling) buttons so it's possible to configure it fully for Linux usage. Tested on Win11 and with Wine 9.0 on Linux (Xubuntu and Fedora Workstation). Other: DPI switch really needs to be on top somewhere, perhaps in front of the ball under the two switches. The RF switch needs to be a pushbutton and MouseAssistant5 needs to be tolerant of connection loss. If the RF switch could cycle between all three connection types it could support three PCs - a very unique feature. Rechargeable would be better than a battery but I can live with the latter. While it doesn't have a incline feature I find the MX Ergo's implementation to be gimmicky and a sloped mouse mat could accomplish the same. I would really like to see a left-handed version as those are rare.

Really great product, easy to install and use, only issue is that the program is totally in Japanese and you can't change the language, so some of the features don't work, but as an over all I really like this Mouse

Ottimo prodotto, sostituisce in maniera perfetta il mio logitech trackman marble wheel che uso da più di 20 anni a filo, per parecchie ore al giorno e l'ho sempre trovato perfetto, mai nessun problema. Volevo prenderne uno per un secondo pc e ho pensato di prendere la versione "rinnovata" (Logitech M570), nulla di più sbagliato, prodotto scomodo, molto più piccolo rispetto al vecchio, quasi subito ho avuto "fastidio" alla mano, il prodotto è un discreto prodotto, non mi aspetterei nulla di meno da logitech (anzi qualcosa in più), ma non ci siamo proprio! Ancora alla ricerca di qualcosa che potesse andare bene trovo questo prodotto, oltre ad avere le connessioni wireless bt e wifi (cosa per me inutile) ha anche la connessione via cavo e molti più tasti (completamente configurabili col suo software). La prima cosa che ho provato è la "comodità" non volevo adattarmi al prodotto, ma era il prodotto che doveva adattarsi a me, questo trackball è perfetto, offre tutte le regolazioni possibili. L'unica cosa "diversa" rispetto al mio vecchio trackball è la dimensione dei tasti principali, essendo 4 (e non 3) ho dovuto configurare 2 tasti come "dx" (in maniera veloce e facile)

Verwende auf Mac mit aktuellem os (m1 Chip) sommer24. WICHTIG:man muss in den Systemeinstellungen der Software Zugriff aufMaussteuerung erlauben , sonst stürzt die Software ab … Hat etwas gedauert bis ich das rausgekommen habe , es kommt eine entsprechende Fehlermeldung ansonsten bevor die Software geschlossen wird . Danach kann die Software gestartet werden und man kann den vielen Tasten verschiedenste Funktionen zuweisen. Haptisch ist die Oberfläche wegen Struktur sehr gut ….

Funciona muy bien. Totalmente personalizables todos los botones.

Fiyatının çok üzerinde bir trackball, hızlı teslim edildi. Mac kullanıyorsanız elecom yazılımı kullanıcı deneyimi olarak çok kötü bunu aklınızda bulundurun. Ellerim büyük fakat konforlu kullanabiliyorum.
