Product review (5 stars): Buy it -- it saves grief
My initial replacement filter was a 3rd party product.  It worked well until it was time to replace it.  We were getting very weird noises from the refrigerator and the water pressure was low.  We thought that we had an issue, not realizing it was due to the filter.  I then bought another 3rd party filter.  It didn't work.  Despite the claims, the filter did not fit our refrigerator and water was pouring out when I tried to install it.  (Fortunately, I was able to return the filter and got a full refund.)  Finally, I paid the price for a Samsung (OEM) filter.  It has been performing perfectly.  The moral is to simply buy this product and spend a few dollars more.
