Product review (3 stars): Stove top is GREAT  - Oven Is Nuts
Prof. 36" Stainless Bertazzoni

Stove top is very nice and easy to clean.  Efficient..steady.  It's perfect.

Oven temperature is controlled by a knob that vaguely indicates oven temperature setting.  I used marker to help me.  was told that temperature is never exact but....
Takes  20-25 minutes to preheat to 350 degrees.
Once the food has heated,the temperature shoots up another 20 degrees.  You have to babysit the temperature.  Serviced twice...they say, " That's just the way it is."
Hmmm.
The cooling fan is always on when baking and it blows in your face when your checking on your food.
The oven is shallow but 36" wide in my case.  I can not put a big pizza pan in this oven.
Even though there are 4 levels you really can only use one cooking shelf at a time unless you can cook both your items very high and very low.
I have never pulled something out of this oven that did not have a burnt spot on it.

Knobs are somewhat cheap but I think they need to be plastic so they don't heat up. We painted the sides of them to indicate when a burner is on.
Looks nice.  Stainless is nice.  Not a complicated machine which is cheaper to maintain.
Not sure what to do....Kind of sad about it.
