Product review (5 stars): Why five stars for this product.
I have been using this type of filter system for nine years now and use it daily. Lots of water drinking and cooking at my house. Very important commodity here in Florida. This type of system  is easy to use, change and maintain. I love the convenience and it is unobtrusive and blends in with the workings of the whole kitchen sink system. That's why the rating is five stars. Thank you.
