Question 1

What does the mx ergo have or do that is worth $60 more than the m570?  just a magnetic hinge and rechargeable battery?

Accepted 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.

Question 2

Does this have the same crappy microswitches that will cause click failures in mere weeks for which your M570 is infamous?

Accepted 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 3

Does the mx ergo have the super fast, gearless “freely spinning” wheel like the mx masters?

Accepted Answer

No "free wheeling" but a simple mod will make the wheel spin freely. I did this on mine after a little apprehension at first. Not sure if will be easily reverted to tactile "cog" movement but it suits me.

Question 4

How well does it work with Linux?

Accepted 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.
