01 FEEL
A little give.
A gasket mount and flex-cut plate take the edge off. The board has a measured softness, never a wobble.

A few good questions
Before it
lands.
Still wondering about a detail? Here are the ones that come up most.
When will my keyboard ship?
Pre-orders ship in 6–8 weeks. We assemble each small batch in Porto and will share a clearer dispatch window as your order gets closer.
Will it work with my computer?
Yes. Kestrel One works with macOS, Windows, Linux, iPadOS and Android over USB-C, 2.4 GHz or Bluetooth 5.3. Both Mac and Windows keycaps are included.
Can I change the switches or keycaps?
The hot-swap PCB accepts 3-pin and 5-pin MX-style switches. The standard MX stem takes the included keycaps and most aftermarket sets.
How long does the battery last?
Expect about 200 hours with lighting off, or about 40 hours with lighting on. Actual battery life varies with brightness and use.
What if it is not for me?
Take 30 days to decide. Returns are no-questions-asked, and every keyboard comes with a two-year warranty.
