Product review (1 stars): Some work, some don't
I've bought these filters twice now for a Samsung refrigerator.  The first two fit and functioned perfectly.  The last one I bought would not work at all - no water flow whatsoever.  Conveniently, the seller (not sold by Amazon for the last purchase) sent me an email asking if I was satisfied with the filter and I replied saying that it didn't work.  Crickets.  Nothing.  No response.  I threw the filter in the trash and now buy a different brand elsewhere.
