Anyway, that ottimo looks very much like one of the uuni/ooni's.
Lots of them on the market now.
I've never used the ottimo, but I am very happy with my uuni. Mine was for wood pellet, but I changed the burner to gas.
These things do have a learning curve. You gotta pay attention and turn the pizza often. Its done within 2 minutes.
Don't use high hydration dough.
Ooni/uuni has a recipe site and those ar dedicated to machines like this.
Almost any flour will work.
