That looks intersting indeed but I still wouldn't know where to put it, I surely wouldn't want to fire that up in my flat... And if you have the room then why not simply build a proper Wood-fired oven yourself?
3 minutes baking time is also way too much for a Neapolitan-style Pizza that he claims it's capable of making - Neapolitan pizza bakes for 90 seconds or 2 minutes maximum. I can currently make a pizza in my modded G3ferrari Napoli in less than 3 minutes already, although it won't have that wood-fired oven taste. Most of the taste comes from proving the dough for a long time and not the burnt wood, though.
If I had the money that the Uuni costs I would buy an Effeuno P134H instead:

If you do come across any videos of the Uuni I'm definitely interested, though.
