Product review (5 stars): So quiet yet so powerful
We purchased this KitchenAid Superba 3/4 hp to replace our Kenmore 1/2 hp.  Our Kenmore was SO loud I wouldn't dare run it while our twins were sleeping for fear it would wake them (therefore it built up an odor due to not using it as often as we should), and when I did turn it on while the twins were awake they would usually start crying if I had it on for more than 5 seconds.  I read disposer reviews on Consumer Reports online before deciding which disposer to get.  First and foremost I wanted a disposer that was very quiet but also powerful enough to grind up most food.  CR gave this disposer an excellent rating for noise (one of the few disposers to get a high rating on that feature) but CR also gave it very good ratings for power.  We paid a plumber $70 to install it and it took him an hour or a little less, so it seemed pretty easy for a qualified person to install.  We've had it for over a week now and I just LOVE it and use it all of the time!  Previously I would scrape all plates over the trash can and rarely put much food in the disposer.  Now I peel veggies over the sink, scrape food off of plates, etc and run the disposer several times a day.  Also, it has a 5 year warranty whereas most other disposers only have a 1 or 2 year warranty.  So that gives me confidence that this disposer will hold up very well over the years.
