Praise
“75레이아웃에 넘버패드를 추가한 세미 풀배열 키보드 에포메이커 특유 고급지고 깔끔한 퀄리티와 마감을 더불어 RGB감성또한 놓치지 않았고 GIF설정으로 책상위의 동반자와 함께할 수 있으며 노브락 기능 덕에 간편한 볼륨조절이 가능합니다”

Critique
“I had to immediately do maintenance on the keyboard right out of the box. A dozen or so switches had to be replaced. There are still keys that do not function, which is mildly annoying to work around.”
