Product review (5 stars): No Problems, and the price was right!!!!
I worried about reports of leakage from other user reviews of almost all of these (replacement) filters.
I chose this one because of generally higher user review ratings than others and price.
The O-ring looked OK, but I worried because my Fridge's original filter had two O-rings.  This has only one.
I replaced it with leakage towels at the ready...  I did not need them, thank goodness.
  Since my new fridge will flash a REPLACE FILTER every 6 months like clockwork, I figured I'd test out a lower cost one first..
After one week, all is well.  I do enjoy the filtered quality of my water and ice from this Samsung.
