Product review (4 stars): Use wash bags to avoid damage to your clothes
Since we don't have hookups and our home is small, this is our next best option.  I'd rather have a full size machine since this one requires your attention to move to each step, but it's doable until we get hookups installed.  It cleans really well, and it can do really small loads, which I like.  The agitator is incredibly strong though, and will easily damage clothes if they are not placed in a wash bag, which reduces the usefulness of the machine somewhat.  Fortunately, I'm mostly using it to wash cloth diaper prefolds which can take a beating.

If you use wash bags, get ones that keep the zipper from opening in the wash, otherwise they WILL open.  Also be sure to get bags with good stitching as this machine has ripped the zippers out of several of my wash bags.

Mine arrived missing a small piece (the lid that goes inside the spinner), but customer service was very responsive and sent me a replacement quickly.

UPDATE: Forgot to add, it does the equivalent of about a 1/3 load in a regular machine.  And it does little for lint.  We ended up getting a dryer partly because line drying takes too long when you have an infant to take care of, and it removes most of the lint.
