I’ve owned a blank WASD board for years. Im no expert typist but i’ve had a similar experience to the author.

Anecdotally it serves as a layer of computer security i didn’t expect. Friends of mine (IT pros, graduate students, programmers, etc) who make their livelihoods on computers throw tantrums completing simple tasks with it, such as typing “youtube” into an address bar. Entering their passwords is particularly impossible exercise in my experience.
