Product review (3 stars): Took awhile to stop leak
Some reviewers said the filter leak.  And that's what happened.  I purged out about 2 gal of water and find after dispensing there are 3-4 drops of water slowly drip out.  Normally I get 1 drip.  I just hold the cup there for additional 1s to catch that drip.  That's the Samsung fridge problem.  Anyway, I just keep using it and had to do some clean up occasionally.  After 1 week of use, it got better and 2 weeks later, it's back to normal, 1 drip.

It is interesting that changing filter would affect the post dispense drip, I never thought about that.  Maybe the filter just gives too much back pressure beginning and the valve cannot handle it.  In any case, it shouldnt take 2 weeks for the filter to stop leakage.  I should be right the first time, but this was about half the price of the OEM, you get what you pay for.
