Product review (1 stars): The most confusing little oven and manual I've ever encountered.
Nonstandard wires (Not Amercian wiring) resulted in poor performance-low heat. Electrician had to call mfr & rewire it. Heats now, but takes 45 min to 1 hr to heat up, then 45 min or more to cool down, with fan going the whole time. Not built for energy efficiency. Fan blows the cooking and chemical smell into kitchen. I heated it per instructions to burn off chemical coating twice. The chemical smell has never gone away.
It requires 15-20 minutes more baking time on average than recipes call for to get the center done for flat cakes and quiche.
The timer does not show how much time is completed or left while cooking, only time of day. Doesn't allow adding time. You have to wait til bell rings then start another time session.  I had to rewrite the manual because it was not accurate for the model, not user friendly language, and was so disorganized. Still trying to figure it out-I only use the baking function. Looking for a replacement wall oven now after a warranty check up.
