Critique
“The keyboard is smooth to the touch, and has the nice feel. For me, it's almost an ideal keyboard but the one thing that gets me and it's a hard issue is that when connected, it takes away input from my controller when I game, especially for live service…”

Praise
“This keyboard is exactly what I was looking for. Low profile, great switches, not uber gamery. Very happy so far, hopefully it keeps working for a long time.”
