The microwave replaces a Frigidaire Gallery Professional that lasted more than 30 years with daily use. The new model is better than the old one in some regards and worse in others.
It looks better and all the lights are much brighter. Sensor Cook may be an improvement if it is reliable.
On the other hand, the new user interface is a disaster particularly with regards to Power Level. I used to be able to set or change Power Level, even when the unit was running, by pressing the Power Level Button and a number (like 4 for 40%). Now, Power Level cannot be set or changed while the unit is running, which means that it does not work with Quick settings. Moreover, having to press the Power Level button multiple times to set a level is ridiculous. Bring back the old method.
I agree with a number of users who complain that the window is too small. One has to stand close to the unit to see inside.
