Product review (5 stars): So far....so good.  Especially for the price
I just installed this thing last night so my review may be a little premature.  But up front, it was super easy to install and works just like the original.  Can't really taste any difference between Samsung's and this one.  Plus, its far cheaper than getting an OEM product.  Some reviews say its smaller than OEM but I didn't really notice.  Maybe a tad but not recognizable to me.  We were having some vibration in the back of the fridge from the water line and couldn't figure out why.  Our last resort was a new filter. This did the trick.  After installing, I ran the water through the dispenser for a gallon or so and viola!  Works like a charm.  No more vibration. Have 3 of these so unless something goes wrong, I won't be purchasing anymore for about a year.  Great product.
