Works fine, media keys all work out the box fedora/cinnamon and you can remap the extra keys however you want, I have the star mapped to Trello and 1 through 5 mapped to particular Trello boards etc.

Been using them with Linux for about 5 years with no issues at all, yet to have one fail, the one I use at work the letters all wore off and I eventually wore through the faux leather padding surface but it's a nice high density foam so it's not breaking up.

I've taken them apart a few times down to boards out and keycaps off to clean them with no issues.

For a properly ergonomic keyboard at that price they are damn hard to beat so much so I have a spare new in box and am thinking of buying another just in case.
