Note that Ellipse/modelfkeyboards is notorious in the keyboard community for poor quality control and support. The keyboards often come misaligned or damaged in shipping, and it's up to you to fix them. I'm not sure about their beam spring keyboards, but their Model F keyboards come without keycaps installed, meaning that the keys haven't even been tested to actuate properly before the keyboard is shipped. If you have the money and free time, you can usually turn what you receive into a working product with enough tweaking. You just have to keep in mind that you'll be paying over $400 for a keyboard that may arrive broken, and if it does you will have as close to no warranty as what's legally possible. If you dig around on forums and in comments you can find a bunch of examples of this, but here's a decent summary: https://consumerrights.wiki/w/Model_F_Labs

Thanks for posting this. I've been looking at getting one but this has made me pause.
