“Even after constant use for several weeks, the switches show no deteriation to quality whatsoever. Very well built too, as the sound is unlike any other”

Critique
“I never recieved the Keyboard because it got lost in the arrival facility. The shipping company nor the manufacturer were helpful, but at least it was a free giveaway I won so I lost no money. It's a bummer I never got it though.”

“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”
