Product review (1 stars): Poor seal/design causes leaks + less effective filter
I was looking for a frugal option to the very expensive Samsung OE filters and stumbled across these.  I went for the 4 pack, thinking it would save me money and time over the long run.  Boy, was I wrong.  Seller shipped quickly, there were no problems there.  The first filter installed and worked fine.  I could tell these filters were perhaps not as effective as the OE filters - the flow rate was very high, suggesting to me that the water was moving through the carbon awfully quick (therefore maybe not as much carbon?).  The first filter lasted a very long time, which struck me as odd, as I thought it should bugger up after awhile.  Anyway, the real trouble started after I replaced the first filter.  The morning after I changed the filter, I can to my kitchen to find my refrigerator and floor flooded.  The filter was not seating properly.  Removing and reinstalling the filter did not correct the problem.  So I tossed the second filter and went for a third.  Same issue - it leaked all over the fridge and floor.  There were no visible defects or issues, but the filter was not seating and locking properly.

At this point, I said screw it and paid the full price for a Samsung OE filter.  Worked perfectly and without issue.

I cannot recommend this in good faith to anyone.  I don't believe the carbon filter itself is anywhere near as effective as the Samsung filters and there were clearly manufacturing/quality issues that proved to be a big headache for me.  I was going for the frugal option, and got the cheap option instead.
