I use the olkb plank (https://olkb.com/planck?category=eotw) both at home and at the office. It started as fun to build, solder, and program but I soon realized that I was less fatigued after typing all day. My wrists don't break outward and I maintain my proper starting position longer as result of having less distance to travel between keystrokes. Take it for what it's worth, but at the very least they are a fun hobby project.
