This is my third replacement Insinkerator garbage disposal unit over the past 30 years. It is very quiet and well constructed. The old unit was still functioning but was 14 years old and was showing its age. The only problem I had was this unit is it is larger in diameter compared to the one I was replacing requiring moving a waste pipe. However, the diameter is increased due to increase in the insulation resulting in a very quiet unit. The magnet control in the cover is an improvement over the previous switch. The only complaint I have is the magnet cover does not allow enough venting when the unit is off and stopper is acting as a cover. This causes water to back up into the sink until the stopper is removed. If insinkerator had a vent hole in the middle of the cover, it would correct the issue.
