I love this oven, but it's far more complicated than my last GE convection oven that this one replaced.  I'm still learning on it.  It seems to take more steps to accomplish what I want.  But I'm sure I'll get used to it! But my other one had the vent on the top of the oven, making the oven easier for short little old me to reach.  If I lose another inch in height (and I'm sure I will!) I'll have to use a step stool to be able to reach the inside of the oven!!
