This microwave seems to function well.  Some of the disappointments include preset timing so that you can't set something for, say, 20 minutes, very noisy operation, and most disappointing of all - the controls panel is dark with fine printing.  One must turn on the overhead light to be able to see clearly the options on the panel.  It is not lighted, which is a huge oversight.  If we had known this before buying, we would definitely NOT bought this unit.
