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.”
JaydenVerified buyer· via Keychron

LUMINKEY V2

8 owner reviews

Praise
“I like the heavy feel. The extra surface area is welcome too; suspected I wouldn't miss the ten key. The right arrow key seems to skip at times, as if I pressed it twice, but maybe it's a fault of my own.”
Nathan H.Verified buyer· via Divinikey
Critique
“I recently purchased the Luminkey 75 v2 through Divinikey. The keyboard itself feels premium, heavy, and well-built. However, since this was drop-shipped directly from the manufacturer, the factory unboxing experience was totally ruined by a bizarre packaging…”
