We bought this in November 2019 to replace a different model.  Some of the features were confusing when we began using it and to this day I rarely use the timer.  Also found the newer ovens heat the air in the oven and not the inside of the oven so it takes longer to preheat.  However, the oven is level and my cakes come out perfect.  Bakes evenly over item in oven. [This review was collected as part of a promotion.]
