I figured i should throw my 2 cents in here. So i have had the roccbox for 6+ months and i can say it does create great pizzas, it is portable, it looks nice. I, however, have changed my mind after some heavy use. While I do think it makes an excellent product, it has a few shortcomings:
1- takes about 1 hour to get the floor to temp for neapolitan pizza
2- if you do 1-3 pizzas you are in pretty good shape regarding the temp staying hot enough, however after the 2nd pie the floor has lost a good amount of heat and it doesn't give you as crisp as a crust as pie 1.
3- its a little small and sometimes is annoying when you are trying to rotate your pizza.
Other than these things it has been a great little oven.
On a side note, i just ordered an uuni pro as they are running a special for national pizza month where they are throwing in a bunch of extras including the gas attachment. I will be reporting back on my thoughts.
