I bought this Moen GX50C garbage disposal to replace an old leaking unit.  It has only been in service for one day so I cannot testify to durability, hence only four stars.  One the plus side it was easy to install, all the parts fit correctly, and it looks like a quality unit.  Almost a shame that it will be hidden from view under the sink. It is also much quieter than the old unit and has a more high quality sound.
