“Keyboard sounds nice, works nice, the software is a bit of an issue to set up as there aren't any proper instructions but you just need the drivers and the VIA app.”

Praise
“I really like this keyboard, particularly due to its ISO PT layout. For the next iteration, I suggest using a higher-quality plastic, as the keycaps feel a bit cheap. I would easily pay 20/30 EUR more if the keyboard felt more premium.”
