Very comfortable but...
I chose this keyboard for the durability of the double-injected keys, the presence of dedicated media keys, the TKL format and the Cherry MX Red switches (I also bought some silicon washers separately to reduce the key noise, which is admittedly quite high).
The keyboard looks very robust and is very comfortable to type on. It works perfectly under Linux (although it's easier to configure the LEDs and themes under Windows first).
Unfortunately, I have two comments:
1. After about a year of use, the green LED under the C key has died, and it only takes one key with the wrong colour to ruin the aesthetics a bit. It's not dramatic, but on a keyboard at this price, it's a shame.
2. The screen-printed keys on the QWERTY model make no sense. The symbols are displayed in the "wrong order" from left to right (SHIFT version first, normal version second, for example, the ">" key).
