In a moment of weakness I bought a soldering iron and this kyria kit [0] and soldered my own. I promise it sounds more crazy than it is and I've been very happy with it.
I've been on an Ergodox Ez for ~4 years now and still love it. Took me about 2 weeks to get back up to full proficiency with it, and the programmability of it is fantastic. I've altered the layout a bit to match my workflow, using the Ergodox Ez web UI. I've got a mix of Cherry brown and Kailh Box White switches in it.
The work K8 was purchased several months (perhaps a year?) after the home one and the build quality is significantly less good than my home K8. The keyboard feels different (both have Gateron Browns) and the printing on the keycaps is crooked. I've also had a couple keys stop working, but banging on the keyboard seems to fix them for a while.
So, I'm not buying any more Keychrons, because I don't know what's going on over there.
I was immediately productive on it and matched my previous typing at 70-90wpm. As opposed to my ergodox-ez which I could muster less than a third of my typing speed. I decided to not spend the extra time to master the ergodox-ez.
I use a Keychron tenkeyless at work, it was relatively inexpensive and came with MacOS keys (a necessity for me). I added O-rings to make it quieter for open office use.
