It's a microwave!  Works like microwaves we've had for the past 30 years.  Nothing special about this one, but it looks very nice mounted in the cabinet above the wall oven.  It states that it is it is 1000 Watt; NO WAY!!!!  As stated, we've had microwaves for over 30 years and, based on past experiences, the TRUE output of the magnetron in the chamber seems to be about 850 Watts.  Cooking times are longer than one would expect with a 1000 watt unit.
