This is our second Bosch double oven, our first being in a former home. While the same series as the one we owned before moving, it could use two features: 1. a louder timer signal when the set time has lapsed, and 2. a quicker preheating period. It can take up to 30 minutes to heat to 350 degrees F. Otherwise the new ovens are wonderful, accurate, and distribute heat evenly in any mode.
