“Lovely keyboard apart from the software and the lightbar on the logo having no inapp customisation Otherwise perfect It could also have more colour options”
Keychron J2

“I absolutely love this keyboard. It sounds amazing and the red switches are so smooth in feel. The colours are also great.”
“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.”
