I've been playing with the uuni today. Not really cooking. Just messing with the fire. I have managed to get it in a sweet spot a few times where it probably would have cooked a nice pizza. I did manage a quesadilla with no soot, and wasn't burnt to a crisp. Started with a smaller fire, cracked the firebox for air, and constant pellet mangagement. I'm going to keep playing.
I said this earlier, but I'll repeat. I think if you can get ahold of the gas attachment, this would be a nice little oven. The fact that it's portable is a major plus, so if you just cook on it without the other stuff it may still be great for someone.
