Product review (5 stars): Clean sparkling crystal clear dishes again!
My dishes were coming out more and more with what looked like chalk or toothpaste all over them.  I purchased this replacement Rinse Aid assemble and it took care of the problem.  Now my dishes are crystal clear again.
The installation is simple and only took a few short minutes.  There are looks of videos on how to install these, so just Google a video and you will see it is not hard.
Very happy with the purchase.
