Overall, I am very pleased with my new wall oven.  It replaces an older different model.  The GE fit the opening with no problem.  I have found the cooking temperature to be correct so no adjustments needed.  Easy to operate and understand.  It was missing the GE logo decal on the front lower stainless steel panel which I wouldn’t have minded but there a three small holes where the decal button is attached.  I contacted the customer service web site after I registered the new wall oven and they immediately mailed me a decal button...no problem.  For the most part, the oven is very quiet although the true convection fan can be heard when I am using the convection feature....not a loud noise but just a little louder than I would like.  I am pleased with my purchase and would recommend this GE model.
