Product review (5 stars): Great filter and seller
How could you give this a bad review? If you put it in wrong and break it; that's called an OPERATOR MALFUNCTION! Or maybe you should be more careful when you jam your 30 pack of Keystone in there! I have bought 4 of these. They are 1/2 the price of a Samsung and the seller (Pure Water Site) gets them to me almost before I order it!
