This microwave does a good job.  I really like the fact that pushing the Start button provides a 30 second warmup for coffee.  But that is the area for my only suggestion for improvement.  The rotation speed for the 30 seconds needs to work like my old one--the cup finished in the same spot it was placed.  Right now my cup winds up toward the back with the handle facing the wrong way.  No biggy, but there's always room for improvement, isn't there?
