I bought this to replace a fridge that was only 5 years old but made so much noise it would wake the dead.  This unit is quiet, the only time you hear it is when it's dumping the ice.  
The only think I've found that I don't care for is the handles for the pull our drawers are on the bottom of the drawers, not the top.  It would have been nice to no bend over so much to open them.
