ONLY HAD THIS FOR A FEW DAYS AND IT WAS A MORE EXPENSIVE MODEL THAN THE ONE I REPLACE BY ANOTHER BRAND, BUT AS THEY SAY, YOU ONLY GET WHAT YOU PAY FOR. THIS IS A MAJOR STEP UP FROM THE OLD ONE THAT WAS IN THE HOUSE WHEN I BOUGHT IT 7 YEARS AGO. I AM IMPRESSED SO FAR, SUPER QUIET, IN FACT I WOULD NEVER SPEND MORE MONEY ON ONE TO GET A FEW LESS DECIBALS.  THE ONLY TIME I HEAR THIS ONE IS WHEN THE DETERGENT DISPENSER OPENS, BARELY. WAY MORE FEATURES THAN I CURRENTLY NEED.  I AM VERY IMPRESSED. I OBVIOUSLY CANNOT COMMENT ON LONGETIVIY BUT IT APPEARS TO BE A QUALITY PRODUCT.
