My Badger 5 bit the dust, so I upgraded to this. Installation was about as easy as it gets with a disposer. This thing is dead quiet - so much so that if the water is on, I have to look at the disposer switch to see if it's on. With the water off, its also very quiet, so I am very pleased.
There is one thing that is different - the baffle between the sink and the disposer -- it's more rigid and the opening is smaller, which slows down the water draining. I get it, it's to make things quieter. This is not a problem, just something I noticed.
