Product review (4 stars): So far so good
I installed one of these a few days ago.  At first, the water spigot on the refrigerator door dripped constantly.  I finally had to turn off the water again, take the filter out and reseat it.  Now it no longer drips and seems to be working well.  I don't know if was my fault for not seating the filter completely, or if this will happen again the next time I replace the filter.  But for now, I'm happy with the savings compared to official Samsung filters.
