Product review (2 stars): Delivery was fast. The filter had dirt on it ...
Delivery was fast.  The filter had dirt on it which I cleaned off before installing.  There were no instructions included or even a bill of sale or return information.  After it was installed water flow was much reduced.  In the future I will go to a local store instead of buying this item from Amazon.  I wish I had read all the reviews before placing my order because others had complaints similar to mine.
