Product review (5 stars): Fast flow, clean water and great tasting.
I was hesitant because it wasn't the original manufacturer filter, but this thing has been working better than the original.  I've replaced the filter with the original Samsung this summer and replaced it with this one a couple of weeks ago.  The water comes out much faster than it ever did with the Samsung filter.  I'm a bit of a water snob and I haven't tasted any off flavors.  It taste like pure, clean water, which is exactly what I want!
