I am thrilled with the performance of the the Versa 16.  It heated up to 900+ degrees in about 14 minutes and produced a great pizza in 5-6 minutes of cooking time. The oven has 2 features we didn't see anywhere else.  First, the rotating stone is a game changer.  No more babysitting the oven and manually rotating the pizza every minute.  Secondly, the Yeti-type rubber closures on the side of oven unbuckle easily and allow the top to pop open for delightfully easy cleaning.
