Product review (1 stars): Buyer beware
Bought these fora new Samsung fridge because I didn't want to pay $50 for the Samsung replacement.  These just flat out don't work.  I ran gallons of water through them but after sitting for just a few minutes when running water through it I d hear water hammer through the fridge really loud.  I had 3 so I pulled it out and put in a new one - same thing.  It was so bad after a week I just pulled the filter.  Today I ponied up the money for a Samsung filter - no water hammer.
