Product review (5 stars): good product, good price, quick service.
Ordered product Thursday, 9/24/2015, it arrived 4 days later on Monday, 9/28/2015.  Removed my old filter and replaced it with this fresh one, ran 2 gallons of water through the new filter, as suggested.  Quick service, good product, good price.  Water is very clear, nothing floating in it, like in some filters I have previously ordered and had to return.  Beware of "after market products".  Would definitely purchase from this company again, as long as they keep their prices reasonable.
