These are great little ovens. I have the same oven, but in the Primavera version. If I were to buy it again I would go for this one, although the stand is hideous. The wrap/center vent helps with draw and also uses the exhaust heat to further insulate the dome. The firing time is 45 minutes or less.
The issue I have is the size - I want a larger oven after using it for a couple of years - and that the oven cracks inside. The cracks seem not to interfere with the performance, though.
All in all, a great backyard oven purchase, no matter which skin you choose.
