This oven has exceeded my expectations! I am an avid baker and spend a huge amount of time in the kitchen cooking for my family. I've used so many of the functions on this oven and I've yet to be disappointed. I bake a lot with yeast and the proof function works perfectly. The racks are sturdy and non stick which is very important when inserting and removing heavy dishes. I like opening the door and the light automatically comes on. Never a dark oven.
