Product review (4 stars): Works great as a cheaper alternative for the brand-name model
We've had this in our Samsung fridge now for about two weeks, and it's been working great.  We haven't noticed any difference in the taste and quality of our water, and it installed just as easily and quickly as the Samsung brand filter.

As other reviewers have noted, this does have a slightly different hole size and shape than the Samsung filter, but it hasn't leaked or caused any problems at all for us.  If it does, I'll be sure to update my review, but, for now, this is a nice alternative to the more expensive model.
