Product review (5 stars): Glad I didn't give into the horror stories
Glad I didn't give into the horror stories.  After replacing with Samsung OEM last time, my water pressure dropped significantly which was irritating.  This time around I gave the water drop a try.  Easy install, perfect fit, appears identical to OEM.  Flushed a couple of gallons through, and the taste is great and the water pressure is back to normal.  No leaking whatsoever.  I guess only time will tell, but my experience is that all of these filters can go way past 6 months.  At this price, I will actually replace twice a year now with no second thoughts about it.
