Product review (5 stars): Perfect fit. No leaks
I've had it in a few weeks now.  I actually did have some trouble getting it in. I twisted it in 3 times and it very promptly popped out 3 x's.  The fourth was the charm.  You just have to take the time to put it in right. I'm not sure what I did differnt but I heard a sound of suction when it went in properly. Perfect fit.  No leaks. Water is clear and good tasting.  This was used for my Samsung Refrigerator..
