Product review (5 stars): Our Water Dispenser works again!
Oddly enough, the replacement filter by Samsung that we bought did not fit perfectly.  We did not realize it was the filter at the time but we pretty much lost functionality of the door water dispenser.  I checked for kinks in the water line and even reinstalled the filter several times.  Still, water pressure was poor and water trickled out of the dispenser.
After 6 months, when it was time to replace the filter again, we went with this one and it works great.  Surprisingly easier to install than the brand name filter and our water dispenser was working like it used to.  We use the dispenser daily, especially to fill baby bottles when mixing formula.  We will not be buying any other filter for our refrigerator other than this one.
