Product review (4 stars): Much better than the cheap knock-offs
This filter does have a smaller opening than the older models as many have pointed out, but I don't think that's a problem.  The last filter I bought before this one was the cheapest one available on Amazon and I had no water pressure to the water dispenser in the door.  I stuck with it since it did work, albeit not so great.  When it was time to replace it, I spent a few more dollars and got the Samsung branded filter. My water pressure is back to normal.  I flushed about a half-gallon of water through it when I first installed it and it has been working great ever since.
