Very easy installation, (taking the old one out was the hardest part), is fairly quiet and seems powerful. Of course most of it is plastic where the 18 year old In-sink-erator it replaced was almost all steel. One thing I really liked is the easily removable splash guard. One thing I didn't like is if your sink isn't stainless steel, you'll be running to the hardware store in the middle of the installation for some plumber's putty. For a couple of pennies, they could have included in the install kit a small rope of plumber's putty for the sink flange. I hope it lasts at least half as long as the old In-sink-erator did!
