I love this oven, the temperature is exact from bake start to end. Takes only minutes to preheat to set temp. All my bake times has been exact, no more baking longer than set time called for. And the app to control the oven from your phone is so amazing. The one handed double doors on this oven makes it fantastic and so easy to use. The lock feature is a plus to have to stop accidental turn ons. No complaints, Love this oven.
