The new unit is very good. It replaced a 27” unit that the microwave was failing on.  Even though the oven is larger, the microwave is smaller.  The unit is very quiet and the microwave cooks faster than my old unit.  I wish there was a way to adjust the brightness of the microwave display.  The oven has a brightness level adjustment option.
Overall the unit is very nice.  I would recommend it.  The oven has many more setting options than the microwave unit and accommodates my large cooking trays. It cooks evenly.
