I like many things about this Microwave/Oven combination.  However, I first noticed that the microwave oven took much longer to heat than my previous oven, as other’s have noted.  This GE microwave’s spec is 1000 W (IEC-705).,where IEC-705 specifies the test to measure the oven wattage.  So, I measured the wattage using the test procedure (heat 1 liter of water for 2 minutes and measure the temperature change).  700 Watts!  Shame on you, General Electric!
