@rho I used an ErgoDox EZ for two years, and would it not be for the Keyboardio Model 01, I'd still use it. It's a fantastic keyboard, highly recommended. It sold me on the split ergonomic design, and I can never go back to traditional (don't want to, either).
It was reasonably easy to get used to it (but I made it harder by switching to Dvorak at the same time), a couple of weeks. I spent _years_ customizing my layout, but I'm an outlier.
Happy to answer any questions you may have, too!
