I recently repalced my 10 yr. old convectional oven with the GE 30" slide-in. I wanted an oven without the wasted drawer on bottom. I love the fact that you can bake 2 dishes at differnet temperatures however I have not used the bottom oven yet. While Baking in top oven there will be a steam that is released along a back panel on cooktop and I have to run my Vent A-hood which is different than anything I have ever cooked on before. I give this product 4 stars because of this reason.
