Product review (5 stars): Good replacement part
This unit is just what I needed and at a fair price.  However, these things do not last forever (this is my third unit, fourth if you count the original).  I guess the heat doesn't do any good for the plastic and it is unfortunate that the dishwasher manufacturer doesn't use a more durable material, but then they wouldn't make continuing profits from selling parts.  I can live with the situation as long as decent replacements like this unit are available.
