Product review (4 stars): Working fine so far.
Seems to work just as well as most large sized dishwashers I've encountered.  It doesn't do silverware as well as I'd like, but everything else comes out clean.
For those of you who already own the product and were maybe having trouble with the sprayer arm not rotating- it's probably your plates in the back blocking it.  My smaller plates hang down below the basket enough to stop the arm from spinning. I fixed that by sticking a butter knife horizontally inside the basket just below the plates to boost them up half an inch.  No problems with the arm since.
