“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…”

Critique
“Meh. I dont like the wood grain and they make it difficult to return or exchange”
