Product review (4 stars): Seems fine after you purge it.
The Samsung filters are ridiculously expensive...especially after the timer triggers you to replace it after 4 months months.  That's $160+ per year in filters....and our water is probably fine just the way it is and doesn't need filtering.

Fry's used to sell the Samsung version for around $35 but stopped carrying it in the stores....so, I came to Amazon and found a number of cheap knock offs like this one.  I got this one because it was the quickest delivery.  There are others on Amazon even cheaper than this but delivery was more than a week.

This filter fits perfectly with no problems.

The first quart of water came out black.  It was more than just bubbles.  But, I purged a couple of gallons through it and it is now fine.

Some people claim that this filter does not meet the specs of the Samsung filter and does not remove as many contaminants.  But, I read the specs and they seem the same as the Samsung, so I don't know what these complainers are complaining about.  But, my water is fine to begin with, so I probably wouldn't be able to tell if there is any difference in the filter performance.
