I first watched this being used in La Taverna Etrusca in Orvieto, Italy. The proprietor took me out back when I showed him my biz card with the brick oven photo on it. We also ate at his place twice because the pizza he made was not just thin; it was 'carta musica' or 'page of music' (that thin).
I showed this to a couple of caterers I've built ovens for and they had to have one.
Of course, the alternative is rolling the dough super-thin by hand, which for home consumption is what I do on principle...generally.
