I got interested in typing ergonomics approximately a year ago when I first heard of the Dvorak keyboard layout. Now I use Colemak more as it feels more balanced with its many special characters and shortcuts for Finnish letters with a diaeresis (å, ä, ö).
More recently I also found the world of ergonomical keyboards and instantly got obsessed with the Ergodox Ez. Their website can be found at the following address:
I just didn't feel tempted to spend 300+ USD on a keyboard with my budget. I also thought that having a mechanical keyboard isn't neccessary for me. That's why I found a budget split keyboard to try out the concept.
I have now had a Perixx PERIBOARD-524B US for a few weeks. I ordered it from Amazon:
https://amazon.com/Perixx-PERIBOARD-524B-Firmware-Ergonomic-Keyboard/dp/B0C9D3PL82/
It costs about sixty dollars and I have now used it a little bit. Not much though, as I have been on furlough only on weekends. It has pretty much everything that Ergodox Ez has got except for mechanical switches and an ortholinear layout. Even though it doesn't have official Linux support it works smoothly on my Void Linux setup.
When holding my hands on the Periboard my wrists feel like they have a more relaxed position. It also has empty space in front of the keys that serves as a wrist rest.
The Periboard comes also with handy feet (haha). They attach to the bottom of the keyboard with magnets. Many people have complained on Amazon that the keyboard is unstable and that its feet fall off easily. The keyboard is indeed very light, and it gets easily tilted over if the user applies force to a key on its far corners but no force to the wrist rests. I haven't had any issues with the feet falling off, though.
Another complaint on Amazon regarding the feet is that they don't allow a lot of adjustements. It's true that it's not possible to tilt the keyboard in any angle, but if you get creative with the positions and angles of the feet you can make it work fine in my experience.
The layout of the keyboard is disappointing, because it keeps the usual tilted columns which are totally unneccessary with split keyboards. With low-profiled hard-to-feel Apple-like membrane keys the layout makes the keys hard to find. It might though just be a skill issue of mine as I haven't got accustomed to the keyboard yet.
It remains to be seen whether my Periboard proves to be better than an ordinary keyboard. It is usable and I think it probably will be better for my hands and typing speed in the long run. For sixty bucks I would say it's worth the money if you are ready to do some compromises.
