Product review (5 stars): My came with stuff inside of it which is not ...
Mine came with stuff inside of it which is not described anywhere in the "manual" that came with it.  There is a gray plastic piece with holes in it which I haven't used.  So far, after tying a dishcloth over the sink connection to prevent water on the ceiling, I have washed two loads.  I am impressed with how much it will wash per load.  The clothes & sheets came out very clean.  You probably won't need more than 1/3 to 1/2 cup liquid laundry detergent.  The directions only address powdered detergents.  The hookup instructions to the sink were very tiny and unclear.  I'm going to go trial-and-error to see if I can stop the leaking, but for now, the dishcloth works.  I give the washer 5 stars...but I only give the instructions 1 star.
