i guess i should have read more reviews.  it's a very nice product, but not reliable.  it has a 1 year warranty and what do you know - the unit totally died 23 days after the warranty expired!  it has only been lightly used and to die at just over 1 year?  unbelievable.  i contacted samsung and they said to schedule a service appt which i would have to pay for.  that would be silly because service and parts would cost more than the $160 microwave!  i guess samsung is not customer focused, has no flexibility in product failure policy and poor product quality to boot.  time to buy a different brand.
