“I'm using it well. However, it would be nice if the right shift key was smaller so there was only one more key. Thank you for making a great keyboard.”

“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”
