Product review (4 stars): Great for mid-sized kitchens
We rent and couldn't plumb a built-in, so it works for us.  There's only two of us, so we don't run it everyday, but it's nice to have so there's less unhappiness about unwashed dishes in the sink.  The best is when we have parties, since cleaning up the aftermath can be daunting the next morning.  We used to have dinner parties 2-3 times a month, we're now up to 3-6 times a month since we got the dishwasher. It does take up a lot of counter space near the sink (you need to connect the hot water hose to it), so I would not recommend to people who can't bear to give up that real estate.
