“This is my first serious mechanical keyboard. It sounds and feels great stock. You don't really need to mod it, but if you do, i think it will sounds amazing. 0 regrets, im very satisfied.”
“I received this item broken: switches, plate, box, stabilizers- everything was either broken or not assembled properly.”

“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”
