We had to buy this unit because our 15 year old microwave went to appliance heaven just as the holidays were getting rolling.  Timing is everything!  This unit does the job, and it is considerably quieter than our old unit.  Although it is a little smaller capacity than our old one,  It has some really nice features.  The only thing lacking is a timer function that was a nice feature of our old one.  Overall, though, very satisfied with this one so far.
