Product review (5 stars): So far, this is a match
To be specific, this review is for the Waterdrop model.  Sometimes the Amazon reviews get aggregated.
This one came with two o-rings, and from all the other reviews, it seemed like the single o-ring models by other aftermarket filter producers are the ones that tend to leak all over your kitchen floor when you try to insert them into a SAMSUNG refrigerator.  I opted for this one over competitors for that reason, and the NSF certifications.  Waterdrop sells this in three different levels, and we bought the top tier (regular, plus, ultra, whatever...) that had two more NSF certs than the SAMSUNG factory filter.  I was hoping for a taste improvement, but I don't think it's any different. Not worse, but no better.  But the price for two was almost 50% cheaper than ONE of the SAMSUNG filters at Lowe's.  So I took a chance and bought some.  I'm very happy with the result thus far.

 I will buy the "Waterdrop NSF 401&53&42 Certified DA29-00020B Replacement Refrigerator Water Filter, Compatible with Samsung DA29-00020B, DA29-00020A, HAF-CIN/EXP, 46-9101-Plus Series (2 Pack)" again.
