Very intresting and this would be so easy to make if you have some scrap metal around.. I bet i could produce same kind
oven for 50$ easily.
I dont think it can be compared to real WFO in any way, but this shure is easy, cheap and portable.
If it cooks under 3 minutes id like to know the size and hydration of the dough. Pizzas looking very dry on photos not good at all...
