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!
