As a long time sufferer of pain and numbness from keyboarding-while-tense, I have moved through many versions and generations of "ergonomic" keyboards. (Starting with the OG Microsoft Natural Keyboard Pro in 1999.)
Imagine my surprise when I went through the short but important learning curve of moving to the X-Bows ortholinear layout, and found out that my issues evaporated immediately and permanently.
As an original backer in 2018, I am a long-term user and can confirm the build quality and general "office appropriate" understated/professional aesthetic of these boards.
The final test was my own foolishness: I became complacent and tried switching back to a standard layout keyboard so that I could share a WFH station with my wife. Imagine my surprise when I found myself flat on the floor with florid RSI from wrist to neck, after many years of not even thinking about it.
Switched back to the X-Bows and within *minutes* the pain began to subside.
I run a Knight Plus at work and a Lite at home, which I will upgrade to a Crystal shortly.
Thank you to X-Bows and Dr. Sig. I can't recommend these enough.
I've been using X-Bow keyboards for years now. Of course, I've looked around for something I liked more...but I always return to my X!
I miss it when I have to use other keyboards
