Vertically slim, but horizontally extra wide door hits you in the face when you open it. It’s even wider than a regular microwave door because it is the full width of the oven, the entire front of the oven is the door. It swings extra far out taking up excess space as it opens. If it was truly space saving it would open upwards, like a hatchback but as it is, the door takes up too much space, like a 2 door sedan in a tight parking spot. Terrible design.
