Praise
“I bought this keyboard to test for work. I love how sturdy it feels, the wood aspects make it feel premium as well. I opted for the banana switches, they do not disturb my colleagues and it feels great for everyday tasks. The battery also seems to hold out…”
Miroslav C.Verified buyer· via Keychron
Critique
“Meh. I dont like the wood grain and they make it difficult to return or exchange”
