Product review (5 stars): A huge convenience
I just purchased this yesterday from a classified listing on CL (the person never used it and bought it through Amazon).  I absolutely hate doing dishes (the one time I did them anyway since moving into my new apartment and buying paper plates).

Hook up was very simple- Just hook up two hoses to the unit, screw on a quick-release adapter to the sink faucet (then hook up the hoses to the sink via the quick-release system), and plug in the unit.  That's it.

I was a little impatient, and forgot to get dishwashing detergent on my way home- so I just washed my dishes with water only, simply to test it out.  To my amazement, the dishes came out sparkling clean, even with no detergent (though the silverware could have benefited slightly from detergent).  I can imagine that detergent would make cleaning pretty much perfect all the way around.  I was also a little apprehensive about there being no mention of a drying cycle.  However, at least with the Santi-wash setting, the dishes are dry within about 15-20 minutes after the washing cycles completes (I think this is partly due to dishes being sufficiently hot such that the water simply evaporates off of them).

I never imagined I could be so happy with a basic appliance, but this thing is really cool, and I no longer dread using my non-paper dishes.
