Had to replace my microwave/oven combo after 30 years and had few choices available.  This microwave door opens down like an oven door and since it's above the oven, it's very difficult to put items in and out of microwave and I cannot reach the back of the microwave to clean up any spills.  Had to get the two step ladder in order to reach.  Takes the oven 10-15 minutes to pre-heat, which is much longer than old one.
