“I love this keyboard. The sound is slightly clicky and mostly creamy. Super smooth to work on. I’ve also set up the RGB to match my PC ones.”

“Keycaps are dyesub, but still PBT Tactile switches feature a proper tactile feeling with great typing experience The case feels and looks really premium layer activation could be nicer but in the end you just gotta get used to the board”
