Product review (1 stars): Slow Leak
Short version: it leaks, do not purchase.  Longer version:  Thinking I'd save a few bucks, I bought and installed this knockoff filter correctly per the Samsung fridge instructions, but after two or so weeks a tiny leak developed in the seal, leaving a pool of water in the bottom of the fridge.  A re-install did not solve the problem.  The water tasted great in the interim, but a slow leak is a deal breaker.  This was after several Samsung replacement filters had been used in the same fridge without incident.  Avoid your cheapskate instincts and stick with the brand replacement.
