Praise
“Perfect addition to my Nuphy Air75 v2. The keys line up well, and this gives me a knob and 10-key when I’m at my desk!”
RyanVerified buyer· via Keychron
Critique
“The K0 MAX is just right with its red Gateron switches! Typing on it feels really natural. 2 Stars less because the battery needs to be loaded again after 3 or four days of occasional usage.”
