Product review (5 stars): Works great!
We just now installed this filter in our Samsung refrigerator, and everything fit perfectly.  I notice this one is a tad smaller in circumference than the original Samsung filter, but I don't know if that will have any effect on the length of time the filter will last or not.  The price was right, the delivery was quick, and I even got an email from the owner (I believe) of the company thanking me for giving the "little guy" a chance.  I will continue to buy these from this supplier, and would recommend it to everyone.
