User questions & answers

Question:	How well does it work with Linux
Answer:	I'm using it with Linux right now, and everything works pretty much as expected. I'm using the Unifying Receiver on a Fedora 28 desktop with X and Bluetooth on a Fedora 29 Beta laptop with Wayland. Everything works on the laptop, and everything but horizontal scrolling works on the desktop. I'm not sure if the difference is X versus Wayland or Unifying Receiver versus Bluetooth. Solaar reports the battery status and easily let me pair it with the unifying receiver I already had on the same machine. It lists two buttons that it doesn't recognize, which I think must correspond to the DPI select button and device switch button. Those work, though, so I don't really care that they don't show in Solaar. Bluetooth also reports accurate battery status in the Gnome control center.
Question:	Does the mx ergo have the super fast, gearless “freely spinning” wheel like the mx masters
Answer:	Nope. It has a cogging mechanism and only recognizes changes between the indents.
Question:	Does this have the same crappy microswitches that will cause click failures in mere weeks for which your M570 is infamous
Answer:	I use mine (M570) for graphic design 8-12 hours a day and yes, IT DOES INDEED HAVE CLICK FAILURE. At one time I had one of our IT staff take it apart and make adjustments to the switches, but the problem came back again in a few weeks. REALLY frustrating when trying to drag and drop objects in a layout, or draw, or even getting a consistent smooth performance for merely highlighting text. It's a legit concern. I need to replace my M570 and am looking at the MX ERGO for the very same reason, but the $100 price tag seems hard to justify.
Question:	What does the mx ergo have or do that is worth $60 more than the m570? just a magnetic hinge and rechargeable battery
Answer:	Yes, yes, and yes!!! I didn't not buy this from Amazon because I wanted to get this right away. I went to Best Buy and got it. I have used the M570 and it was quite good. I had an older keyboard so first upgraded to ergo k860, OMG!!!! what a difference.... then I thought I should try the vertical mouse first. Returned this on the next day. Then I looked at the Logitech Master MX 3 because it had the most features..... Returned this to the next day because once you go a trackball, you won't be back to a regular mouse. Then, before I decided to try MX Ergo, I thought I should just keep m570 because it was better than the first two: vertical mouse and mx master mx3 but then I thought it wouldn't be fair to not try MX Ergo. I AM GLAD, I DID!!! your wrist is going to be thanking you for years!!! Love it! The programmable features are awesome! I work from home and this is must to have nowadays.

User questions & answers

Question:	can this be used by left handed person...person has NO use of right hand
Answer:	I have an earlier, non-programmable version which I purchased from Amazon in 2003 and it still works like new. I am actually right-handed, but I have always used it with my left hand because that placement is perferable to me. I have used it on both mac and linux operating systems. In either case, it is simple to configure for the left.
Question:	I have this mouse and I LOVWE it! I like that the ball sits on top. Does this come in a wireless version
Answer:	Is there a wireless version that is NOT a thumb rollerball? (thumb arthritis).I am looking for one JUST LIKE THIS... finger controlled trackball... and one that is not $280-$500 as listed here on Amazon.The "wireless" Logitech at Office Max and Office Depot is the Logitech marble trackball ( "thumb" ) mouse. $489http://www.amazon.com/Logitech-Cordless-Optical-Trackman-USB/dp/B00006B9CR/ref=sr_1_14?ie=UTF8&qid=1402505757&sr=8-14&keywords=wireless+trackballhttp://www.amazon.com/s/ref=sr_nr_p_89_0?rh=i%3Aaps%2Ck%3Awireless+mouse+or+trackball+Logitech%2Cp_89%3ALogitech&keywords=wireless+mouse+or+trackball+Logitech&ie=UTF8&qid=1402505574&rnid=2528832011
Question:	Does it work with Linux Ubuntu laptops
Answer:	I'm running Debian Stable (Ubuntu is based on Debian), and tracking/clicking worked right out of the box, including the "forward" and "back" buttons. I used the ArchWiki0 instructions for tweaking the configuration to what works best for me1. 0: https://wiki.archlinux.org/index.php/Logitech_Marble_Mouse 1: https://pastebin.com/A3dCjtJR
Question:	Does the Logitech Trackman have a scroll option
Answer:	In addition to the Setpoint software made by Logitech, I also installed a small program called "MarbleScroll". You can get it here with instructions from its creator: http://www.fewprojects.com/marblescroll-for-logitech-trackman-marble/. Works flawlessly. However, note that there doesn't seem to be an option to have it stay on after restarting your pc, but you can set it up to be part of your pc's startup routine. Easy to Google and do it yourself. After that, the product is perfect.

User questions & answers

Question:	Has the ergo m575 replaced the m570? one uses optical and the other laser
Answer:	Assuming you have the proper drivers, it should.
Question:	Does anyone else have an issue with the scrolling to be "jumpy"? i even find the trackball to be "jumpy" too. using a macbook pro
Answer:	No. Serial is 9 pins. VGA is 15 pins.
Question:	Is this bigger than the M
Answer:	yes
Question:	Stated as being first available January 2021.. How come the comments years before
Answer:	Depending on your desktop or laptop configuration, you will likely need more than one. I'm using a three monitor setup as I write this, but I had to buy (2) of the adapters, plus I ran one monitor straight to my laptop. The general rule is one adapter per screen; with the caveat that monitors you can run straight into your laptop don't need an adapter.
