Product review (5 stars): We love this oven
If you need two ovens and only have room for one, this is a great oven.  Yes, the lower oven may be a little tight if you're cooking an enormous turkey, but believe me, it's plenty big for a 15 lb turkey or a big standing rib roast.  Both ovens preheat very quickly, around 10 minutes.  It's also really nice to have the shorter doors, so you don't have to reach over as far (compared to a standard size oven) when you're loading and unloading the ovens.  We use the smaller, upper oven the most.  It's plenty big for baking cookies, muffins, pizza, meat loaf, Pillsbury cresent rolls, lasagna...  It's kind of like having a big, commercial quality toaster oven.  In fact, we decided to get rid of our countertop toaster oven and gained back that counterspace.

Each oven also has two oven lights, located in the back corners, so you can see inside really well.

In my opinion, the cooling fan really isn't that noisy.  The exhaust fan above your range, set at the lowest speed, is probably noisier.

I agree with the other reviewer regarding the possibility of spilling liquid into the electronics located inside the upper oven door.  GE should have designed the upper door with a drip guard, to keep stuff from falling into the slots.  I would really rate this oven 4.7 stars.

My advice if you are considering this oven is to check it out first at the appliance store (we found it installed in the display kitchens at Lowes Home Improvement).  Get a good feel of the size of the ovens and the rack positions.  You get one rack for the upper oven and two racks for the lower oven.  Make sure that will be enough for your needs. BTW, you cannot interchange the upper and lower oven racks.  Ponder it carefully.  Become "one with the oven".  We did this 3 times, to make sure that it could handle the types of baking we do.  This is a relatively expensive oven, so make sure it will fit your needs.

Again, we love it.
