We have the oven for the past 3 weeks use and are very satisfied. The criticisms of earlier recessions the company Rommelsbacher has taken off and obviously to the heart. Top and bottom heat can be operated either with or without air circulation. Crumb tray is available, nothing rattles or vibrates. We have pre-baked frozen products but also prepared Hawaii toast and even baked bread. (Baking mix) The oven preheats quickly and cools off quickly. This oven is recommended without reservation. The existing interior lighting we find helpful. Torsten S.
