Product review (5 stars): Why buy one anywhere else?
I have been buying my refrigerator water filters from Amazon since the first one.  It was so inconvenient when it went out and I had no idea where to buy one.  I checked on amazon and figured out which one to order.  Now when the replace light goes on, I go on Amazon and see what I ordered last, reorder and the next time I think about it it's being delivered.
