I did not give the oven 5 Stars because it takes so long to heat up. I was shocked how long it takes compared to my 23 year old GE Profile Oven I replaced. I timed it today and it took 15 minutes to get to 350 degrees. I love the WIFI, so i can turn the oven on to preheat before I leave my office, so it will be ready when i get home. I have talked with a friend that bought the model below mine a few months ago and she had the same complaint. Also, the bottom metal trim piece is much smaller than before and exposes the old color of cabinet that was hidden by previous oven. An installer told me I should have had two different trim pieces to select from with the GE Fit Guarantee.
