Product review (5 stars): Ya gotta luv it!
My  dishwasher is at least ten years old but one would never know it because I have been using Water Sentinel WSD-1 Dishwasher Water Filter for a long time now.  The inside of my dishwasher is just as sparkling clean as the day it was installed.  The product is well worth the cost as far as I am concerned.  I am not a paid reviewer, just your average housewife and I honestly believe in this product.
