Is it Linux compatible?
Yes.
Does it have NKRO (n-key rollover)?
Yes, it has N-key rollover internally (each key has a diode), which means that you can type any combination of keys. There will be no ghosting or phantom keys.
However, USB imposes a bottleneck that limits it to a maximum of 6 keys + 4 modifier keys pressed simultaneously — but this is more than enough for even the fastest typist.
In fact, if one hand is holding down modifier keys (or is on the mouse) then you only have 5 fingers available on the other hand for pressing keys — which the 6 key limit is more than sufficient to accommodate.
R O U T I N E C L E A N I N G (monthly):
- Run a vacuum brush over the top of the keyboard.
Alternatively, a compressed air can is also a good way to blow dust out from under the keys.

- Wipe the top and bottom of the keyboard with a damp (not dripping) cloth.
D E E P C L E A N I N G (not generally recommended):
If your keyboard is working properly, we STRONGLY recommend AGAINST deep cleaning it.
These instructions are provided only for cleaning keyboards that are so dirty that they're not functioning properly — for example: sticking or non-working keys, etc.
Deep cleaning will void your warranty, so if your keyboard is less than a year old, we especially don't recommend doing this. Better to contact us for warranty support instead.
For a more rigorous cleaning, you can remove some of the key caps. This allows you to get under the keys and vacuum out anything missed by regular cleaning (for example, crumbs or larger bits of dust).
- To avoid damaging the switches, you need a proper "key puller" tool to remove the key caps. Here are a few options:

- Pull straight upward with the key puller, to remove each key cap.
- The bigger keys must NOT be removed, because they are extremely difficult to put back on afterwards...
- Spacebar
- Shift keys
- Return/Enter
- Delete/Backspace
- numberpad Enter
- numberpad 0 (zero)
These keys must NOT be removed. You can clean under these keys by removing some keys around them.
- We do NOT recommend opening the keyboard case enclosure, for several reasons...
- It voids the warranty.
- If you're not careful, you can easily damage the electronics from electrostatic discharge (ESD).
- It's difficult to re-assemble the case if you don't know how.
- It's not necessary for cleaning.
- After the key caps are removed, simply vacuum out any dust and debris from inside the keyboard. Do NOT use water.
- The key caps themselves can be cleaned by running them through a dishwasher. Wipe them down and let them dry out for a few hours before popping them back on to the keyboard.

If the keyboard is so filthy that it appears to be a lost cause—as it
might after a major coffee, soda, or Mai Tai spill—put it in the
dishwasher. Place it in the top rack, dial the dishwasher to a rinse only
setting, don't put soap in the thing, and run it through. Remove the
keyboard and let it drain, with keys down, until it's completely dry—this
could take a couple of days.
This is controversial because some keyboard manufacturers suggest that you
not do this as they won't guarantee that the keyboard will survive the
ordeal—particularly if you hit the keyboard with really hot water,
detergent, and flying cutlery.
Speaking from personal experience, I've done this with a beloved Matias
TactilePro keyboard that I'd given up for dead (this is the perfect
condition under which to conduct this experiment). I'm happy to report
that not only did it survive, it works perfectly (and is a whole lot nicer
to look at than it once was).
