I used the pizza stone with homemade pizzas and they came out great! brown on top and crispy on bottom. I actually struggled with the settings at first because I thought there must be more steps that I would have to go through. There weren't, this oven is just very easy to use.
Two of these have malfunctioned in 8 months with the first one turning on by itself and the latest one starting to lose letters on the digital display. Getting a warranty replacement has been an exercise in futility. I regret my purchase.
Just died on me last night. Some digital letters in the mode selection were already breaking up and hard to read, at least a year ago. Not very user friendly; tricky to use the touch pad, requiring lots of entries and re-entries. Once started, the oven worked quite well. The digital thermometer was accurate with a fairly quick heating up. Cooked all sorts of things including five pounds chicken that had to be butterflied to fit under the top element. Paid $160 in late '16 and assuming the electronics are the same cheap stuff, this oven is not good value.
