November,
I know these ovens very well, I was just trying to be objective with what is visible without going into too much details as you are aware I am involved with another product. A friend of mine also has a smaller home version.... still with the same issues... I would not even have replied if I was not sure of what I was saying....
If you had tried wood ovens, good and bad, we could have a nice discussion about this, but there is no point about discussing theory on this....
The mouth is too large in proportion, to all their model, and that is one of the reason their oven consume too much wood, and they use a type of brick that could be good for a certain application but not so good for another application.
Dimensions, shapes etc.. do not re-assemble a neapolitan pizza oven, and I believe shango trys to replicate that type of pizza.
regards
