“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
“Keyboard works well, but the screen has been very glitchy for me, making it hard to adjust the rgb. In general the hardware is fussy, but is a okay case and good for the price.”

Critique
