Product review (1 stars): I like to purchase filters ahead of time
Buyer Beware - This filter has a large hole and leaks.  I purchased a 2 pack in Feb and opened filter box to install today July 20.  I like to purchase filters ahead of time.  My recommendation, if you purchase these filters, open right away even if you're going to store for future use so you can return or exchange.  The picture shows the Samsung filter that I took out of my refrigerator (small hole) and the new R-9101 filter with large hole.  Even the filter box shows a small hole!
