This oven replaced a GE oven I had used for 26 years (with not one repair!!) so I decided to stick with GE when we remodeled.  First, I will share some irritating things.  A new feature for me is the preheat function.  It takes 14 minutes for the oven to heat up to 350.  This seems like a really long time to me, but perhaps for the last 26 years I had been placing food in my oven before it had reached the correct temperature since it did not have a preheat feature.  Another issue is that it seems to cook a little hotter, so I usually decrease the recommended setting by about 5 degrees.  The final thing I dislike (and this may be a safety feature), is the fan that blows heat into the room after the oven is turned off.  I don't know where the heat from my old oven went, but it did not blow back into the room.  Some positive things now.  It is very attractive, has a lot of features, and the self-cleaning odor is much more tolerable than that of my previous oven.
