Loved by the people who type a lot.

I write code for a living. My K-04 has been on my desk for 14 months. I notice it the way I notice my coffee — never, until it's gone.

The thock is real. The tactile bump is real. It made me a better writer because it made writing feel like building something.

We bought 40 for the engineering floor. Six months in, the only complaint is that the team won't use the office Magic Keyboards anymore.

I've owned 11 keyboards. This is the last one I'll buy this decade. Maybe ever.

With Brown switches and the included silicone dampening, the K-04 measures 48 dB at the typist position — quieter than most laptop keyboards. Blue switches are loud by design.

Yes — and Linux. A physical switch on the side flips the layout. Keycaps for both systems ship in the box.

Pull a switch with the included puller, drop in a new one. No solder, no firmware, no fuss. We ship a keyboard, not a kit.

Two years on the keyboard, lifetime on the chassis. Free replacement switches for 12 months if any fail.
