Product review (4 stars): Great Water Saver
A few years ago my well pump broke and I used the wonderwash while waiting for the pump to be replaced.  The washer uses very little water and got my clothes clean. I am planning on dragging it out again this summer. If you are using hot water, it tends to make a vaccuum and it can be difficult to open.  I am giving it 4 stars only because it needs a wringer to be really useful.  Hand wringing is a major drag.  If you don't have a wringer, it is best to use in the summer when you can line dry.
