We have several other Bosch appliances that have been purchased to replace the original appliances in our home. Without fail, these have been superior to the originals. This Bosch oven is no exception. Though it is the same panel size (27"), it is much bigger inside, probably a result of better insulation design. I'm responsible for the turkey every year - the roasting pan that I had to wedge into the old oven now fits with room to spare. The oven did a perfect job on the turkey. And, my wife has made several batches of cookies and is extremely pleased with both regular and convection baking - she was afraid to try convection baking with the old oven.
