I bought this about 6 weeks ago and love it so far. We did have a problem with the display board in the microwave / convection oven that we bought too, but GE replaced it within 2 weeks with no hassle.
We purchased a new home and were able to choose our upgrades accordingly. I was a bit concerned since our last oven, a high-end brand that performed well, was a bit fickle and often had to be calibrated to adjust the temperature. While my experience with this new oven is little, I have noticed that it consistently completes the baking time in accordance with the recipe. No more guess work or fear that a time-consuming cake recipe will be a flop!
