Of course, I need to do a better job at advertising and keeping up with trends like OLED screens and rotary knobs. But as a plain-Jane Bluetooth split ortho keyboard, I fervently enjoy typing on it.

I would really recommend anyone who looks into buying one to also buy the palm rest since it's a pretty thick keyboard. I use a tenting setup and I don't think I would be able to do it comfortably without the palm rests.

A few months ago the key cluster arrived as well - it feels kind of gimmicky though since all I use it for is play/pause/next song and to switch to my chat workspace. Others might have better use for it though. The scroll wheel is nice but I'm already used to the mouse layer on the keyboard, so I seldom use it.

My only gripe is the USB-connection. The v1 uses a mini-USB connection that I felt would be the first thing to break on the keyboard (since the rest of the keyboard feels like it would outlive me), so I soldered one of those magnetic cable heads to the keyboard and bought a few cables that I have lying at every desktop I use, "mag-safe".

I haven’t used the new UHK, any of their addons, or the palm rest, so I can’t speak to those.

This one is hilarious, the design caught my eye with its unique shape and the mandatory pro-Mormon proclamation (which at first I thought was a joke about the shape of the hands on the keyboard being prayer-like) until the creator told me to repent my sins.

I have always believed that the problem with ergonomic keyboard design could be solved for a majority of cases with one single design, optimised over a number of generations rapidly in about 3 years (or a more optimal period allowing you to iterate retail cycles and customer reviews and reactions as well as observations in actual use) and make a excellent long term investment for a relatively small amount of capital.

the capital amount of course wouldn't be small in every individual view of small, but I can definitely imagine the required capital investment can be kept in check within less than -$3mm and return overall very well real inflation adjusted over a very decent length of time.

(i tend to presume the existence of very strong IP law knowledge in the design and development and management team - this i would like to be overlapping roles - but about one third of the capital in any project like this would be allocated by me to legal and IP rights protection in any event because you don't want to be responsible for that with only product development experience no matter how well educated in IP law and practice you are . Product liability and environmental and ethical concerns would receive a significant budget today as well , especially when everything is outsourced (Logitech since 30 years effectively in the beginning ...)

I used them for PgUp/PgDown (to scroll up/down in a terminal), mouse wheel scroll, and cursor keys.

However, my hack job eventually caused problems. I think I had an intermittent short somewhere. I removed the knobs, and I don't miss them.

I may add a knob on a horizontal rather than vertical axis, but I should 3D print something to hold it in the correct place if I do this.

pretty much all of them seem to be DIY, or, simply out of stock

The ones under "Assembled" are from small businesses or side businesses, or at times may be unavailable for months, or have week+ delays before delivery. There are some companies like https://falba.tech/ (EU) and https://bastardkb.com/ (Canada?) who make several models.
