I originally posted a good review of this product, but after a month of use, I must give it a poor one. I am unable to edit my initial review, so I'm posting another one. After only a month of use, the water dispenses at 1 cup per minute with this water filter installed. I'm sure it must be a bad filter, but what's really frustrating is that SAMSUNG will not guarantee this product. I called SAMSUNG customer support only to be told that even though it is a defective product, SAMSUNG cannot replace this product and that I would have to eat up the cost. What their rep said was that the filter is actually produced by another company and branded as SAMSUNG and that's why they can't help with a product that bears their name. BUY THIS PRODUCT AT YOUR OWN RISK. SAMSUNG will not help you with this water filter.
