Wesentlich besser, als die Logitech Mäuse, die ich viele Jahre benutzt habe. Kann man wirklich nicht meckern

This trackball mouse has been a lifesaver for my wrist pain! Switching to this design has drastically reduced the strain I used to feel after long hours of work. The thumb-operated ball makes scrolling and navigating so easy and precise—it’s incredibly intuitive once you get used to it.The ergonomic design is comfortable to hold, and the customizable buttons are a nice bonus for streamlining tasks. It’s also great for limited desk space since you don’t need to move the mouse around.If you’re dealing with wrist discomfort or just want a more efficient way to navigate, this trackball mouse is a game-changer. Highly recommend it for anyone looking for comfort and functionality in their setup!

I like optimizing with keyboard shortcuts and scripts so having a mouse that has the ability to function in place of some of my most used shortcuts is really helpful. If I were to go back I would buy the 8 button version just so I could have my copy/paste/cut, redo, undo, etc. But this one does a great job and the software is customizable so you can program new shortcuts(only 2 key commands cmd+c, ctrl+c, etc.) and create presets.The trackball movement it smooth and overall it's a comfortable mouse. For the price, it comes with a lot of functionality and features!

The mouse is good and all the buttons work nicely with decent options on the customization app, however the track ball although is working fine it's not fully firm in it's position and slightly loosely fitted in it's placeIt might not be a big deal but I hoped that it was designed to be more firm in it's socket for easy and accurate tracking

Tek kötü yönü çok çabuk pil tüketiyor. Daha önceden logitech tracball kullanıyordum ortalama pil ömrü1 yıla kadar uzuyordu bu en fazla 3 ay hemde tasarruf modunda kullandığım halde.

كل شي جميل وبتصميم انيق فقط لو الحجم اكبر بقليل

The buttons have a break in period where they hang and stick, eventually they wear in and work correctly.The button design is not comfortable and way to easy to accidentally click for the left and right buttons, and the left and right scroll. and is not ergonomic or designed for the human hand to use easily.It is a usable but kinda unpleasant device to use, you have to learn how to use it rather than it feeling natural. It is cheaply made and poorly designed.I will likely be keeping it as it works acceptably after a short break in period and the function keys work well for gaming, but I won't be buying another as I am not impressed with the build quality or feel of the device..It gets the job done, but is not great at it. Unfortunately I have not seen a better gaming trackball yet. Which is disappointing.It's build quality makes the Logitech M750 seem well designed and robust. (The M750 repeatedly failed for me 6-9 months after purchase like clockwork)Hopefully this one holds up better. But I kinda hope it doesn't so I have an excuse to buy a different brand.It really is a mediocre device.Update 5/18/2022After a break in period, the mouse buttons work more reliably, but accidental clicks are still an issue, but the scroll wheel stopped working, it occasionally reverses direction while scrolling making it unusable... Two months after purchase.Update 10/15/2024Amazingly the trackball is still working, The main mouse buttons all work correctly, but the middle mouse-wheel button is worn out and rarely works, it often double clicks when it does, I found a way to remap the input on the mouse-wheel so that scroll works properly on Linux, for some reason the mouse wheel was throwing out multiple button codes for each scroll event. It still doesn't work right on windows.Extra buttons can be reprogrammed on Linux using a program called Input RemapperThe main issue I have found with this device is that the wireless receiver randomly loses connection and loses range over time. For the longest time I thought my computer freezing issues were due to running Firefox in snap on Ubuntu Linux, until I had two mice connected to the same computer and found that it was the wireless signal hanging instead. I found that I had to unplug the receiver and power-cycle the mouse to get it working again.Also the receiver initially worked up to 30 feet from the computer, but now it barely works when it is 5 feet away and needs direct line of sight to the plug. The gradual and random failures made me think my computer was having ram or storage issues.I want to hate this device, not because it is bad but because it could be so much better, Even with all its many issues it is much much longer lasting than the Logitech equivalent and has better features (when they work). Reluctantly changed rating from 1 star to 4 Due to longevity and reliability of main buttons.It Isn't great, but it blows Logitech out of the water in longevity and reliability. Which is a scathing condemnation of Logitech.I will probably be buying the next step up from Elcom (the EX-G Pro (M-XPT1MRXBK)) because the extra buttons and response rate are great for gaming, it also supports Bluetooth and wired connections so the crappy receiver won't be an issue.I would prefer to buy Logitech, but they keep phoning it in on features and using shoddy switches that break way too fast. Elecom is an acceptable substitute that makes me hate the fact that I love trackballs.Computer trackballs should not induce Stockholm Syndrome.

I've used three Logitech trackballs over the years:- M570- Original Marble- MX ErgoThe M570 just quit working one day. Something I've noticed about Logitech mice and the Logitech keyboard and trackpad combo; The connection to the USB dongle is spotty at best, even when it's 1 foot from each other and new batteries.The Marble was a hand me down. There was a spot (chip) that would constantly snag. Just last week I used a piece of sandpaper to smooth it out, but in doing so, made the surface rough and the trackball wouldn't glide as efficient, but was slightly better than when it had a divot.The MX Ergo is sitting on my desk at work, unused, as I've been WFH since March due to Covid-19. So instead of going down there to retrieve it, I ordered this trackball mouse and I'm very happy with it. Ironically enough, it's a Japanese designed mouse, not Chinese. It flows very smooth and its quite responsive. I actually have it set to the lowest mouse scroll setting and it's still quite fast. It's still fast when you flip the switch to precision. Unchecking the Enhance Pointer Precision box in the Mouse Properties speeds up the mouse very fast. Wish there was an actual driver to dial in the settings vs using the WIndows mouse properties. Other than that, I'm happy with this purchase and highly recommend. I haven't had an issue with wireless connectivity, either.

Bought this as the switches in my 1st generation Elecom wireless trackball (M-XT1DRBK) started playing up. It was far easier to buy a new mouse, and I'm damn glad I did.The external design hasn't changed from Gen1 - they physically look identical - save for the forward and back buttons, which are now of a lower profile. This is a good thing - it was a fantastic thing to hold in the first place.Popping the trackball out reveals the artificial ruby bearings, which are much larger than the ceramic ones previously used. Having only used it for a day I can say that the movement is more positive, albeit a bit scratchier. A bit of PTFE on the bearings might fix that. No comment on maintenance intervals yet as I haven't had it for long enough - Gen1 lasted about a week or so before needing cleaning so I expect this to last longer.The two biggest changes in terms of feel are the switches for left/right click, and the scroll wheel - these are the reasons I'm glad I upgraded.The switches weight are perfect, being a little on the heavy side, with a loud and tactile engagement. Blows Gen1 out of the water in this aspect, even when they did work properly.The second change - the scroll wheel - is minor but makes a huge difference. Since the first day I got the Gen1 trackball the scroll wheel always drove me up the wall, as the scroll wheel had a lot of play; it would move up and down whilst scrolling, and when clicking it would move forwards, and therefore never delivered consistent performance or positive feedback. The new scroll wheel is much better though, despite the wheel itself not changing.Overall this is a great option for a thumb trackball, and is very reasonably priced for what you get. Better than previous generations AND the M570. The Logitech MX Ergo would have to deliver unbelievable performance to top this.
