Took 20 min to preheat .had 2 prior GE monograms and /or top of line . Each lasted 14 yr. Cooked great . Had converted oven.
Was told didn’t need online set up Not true Told worked great . 
Very easy . Conv oven and regular one take much longer . It’s crazy. Your tech was great , he had no clue u needed Wi-Fi for 
conv roast. I had ordered a Viking but didn’t arrive after I yr so 
went to what I had and sales person said it was great . Reviews 
were good . It’s a big disappointment right now snd  only praying it will cook Turkey okay . It’s scary
