ZSA Voyager for over a year now, and the other ZSA boards since about 2018.
I've been really happy with it, and it helps me type fast. I do tend to slam the keys down sometimes but it's held up great. I was able to stop using a mouse- the key-driven mouse motion is intuitive enough for me.
Took me a bit to get used to the reduced key layout, but it's actually turned out to be just enough. I see some people with even fewer keys! Will need to try that out sometime.
Just running a base hardware configuration with Kalih Choc Brown switches and a custom layout that does not use any chording or timing-based layer switching, only holding.
Would like to try building my own someday.
