Product review (4 stars): The water is pretty good. I'll be buying the filters again soon
I bought the WSS-1 Water Sentinel in a four pack so that I didn't need to repeatedly buy from Amazon.

WARNING.  The replacement is bigger than the Samsung filter.  You have to push the filter under and jimmy it in.  Then you have to let it file the water through.

The water is pretty good.  I'll be buying the filters again soon.
