“Este es uno de los teclados más extraños que he usado y requiere desaprender (memoria muscular) para disfrutar de el y creanme que vale la pena. Lo super recomiendo.”

“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”
