After installing the unit and turning the unit on, the first thing we noticed was how quiet it was, actually thought the motor was not working properly. After turning it on/off a couple of times and trying it we determined that the garburator is actually that quiet, and works very well. Noticed that the water does not drain as quickly as the old one, but it's certainly acceptable. Appreciate that the splash guard is replaceable and can be taken out and cleaned. Very satisfied with unit.
