Praise
“I absolutely love this keyboard. It sounds amazing and the red switches are so smooth in feel. The colours are also great.”
WojciechVerified buyer· via Keychron
Critique
“The keyboard is nice, but it took over 3 weeks of shipping to arrive. On their website it says they deliver in a week or under to the US.”
