Product review (5 stars): Bought from Sears
I am a fan of this dishwasher, I've had it for about two months now.  It's quiet, has a sensor cycle, and apparently it's very energy efficient.  What's great about the dishwasher is that it cleans very well when I use the sensor cycle.  What's not so great?

The lower rack is not very versatile for different dish configurations. The top rack is much more flexible and can load a variety of dishes/bowls/cups.  The lower rack seems reserved for large dishes and does not allow many different configurations.

Aside from that, and it's not really that big a deal - this washer has been great and cleans exceptionally well.  It's a good buy for the price (I got it for $500 at Sears).  Even for six I think it would be a good deal.
