I don't have any of the essential line of switches. I never expected to etch any of my keypads or switches, so I might have tried them.
I therefore feel pretty comfortable saying the the real version. I have, over time, engraved every single switch and keypad I have. With a smart home, it's kind of critical that you (and your guests!) Know what buttons do. Totally worth it and really, if you are spending that much money already, just do it right.....
