This machine came pre-installed in the home I purchased. I've been using it for over a month now and it has to be one of the quietest machines i've ever used or been around. It cleans dishes quite well, I haven't yet noticed any funky odors coming from it. I could be sitting in my kitchen when it's running and hardly notice it working, just the occassional running water noise but easy to carry a conversation over it without raising your voice. Great for those spaces where the living room and kitchen aren't separated and it needs to run.
