Purchased this new GE double wall oven 1 month ago.  Very easy to install. Love the features - I didn't think I would use the blue tooth app but it has actually came in very handy.  I am notified when the oven is preheated which is awesome - no more standing in the kitchen waiting and watching for a oven to preheat. I am very impressed with the quietness of the oven - I pray it stays that way as it ages.  Love the slate color and does not show the finger prints as stated in the product description.
