Love the oven as a whole. The cooktop is great and very efficient. The upper oven bakes well without having convention. the lower oven is good but takes about 30% longer to heat up. Only beef is that my extra large cookie sheets aren’t able to sit level on the racks because of how the ball bearing rack is designed. I’ll likely move that rack to the upper and keep the regular racks down below so I can bake two large trays of things simultaneously with convection.
