We owned a predecessor model for 26 years before failure.  The newer one has pros & cons.  Big pro is the interior cabinet.  Much easier to clean, no crevasses. The turntable is smaller and so is the overall unit but the interior design allows for basically the same capacity.  It is a lot quieter.  The lighting is not as good and it's harder to see through the door.  The key pad lettering is not as well accented and is difficult to read.  It's too bad these features went down hill from the original but the overall product meets our needs and looks good in the kitchen.
