If you have been using an ergonomic mechanical keyboard for more than year, let us know which keyboard it is, and whether you plan to keep to keep using it for at least another year or if there's another keyboard you are considering trying instead.
I've been using the Piantor by Beekeeb for over a year now. I started with the 42 key version, but after a time broke off the outer columns and am using 32 keys.
I'd really only change my daily driver to go wireless, with something like the Chocofi.
That's not to say I don't dabble with smaller keyboards just for fun 😊 I use a 16-key on and off, but I'm not very fast on it yet.
