THIS UNIT WAS VERY EASY TO INSTALL  .FROM REMOVAL TO RUNNING IN ABOUT 30 MIN . I REALLY LIKE THE NEW GASKET FOR THE STAINLESS STEEL SINK . NO MESSY PLUMBERS PUTTY NEEDED. FLANGE WAS TIGHT BUT AFTER A LITTLE DISH SOAP WENT IN EASY . I'VE HAD A LOT OF GE APPLIANCES OVER THE YEARS .HOPE THIS ONE LASTS AS LONG AS THE OTHERS   ..
