Product review (5 stars): Frugal deal.
I received my order of three filters about two hours ago and installed them. So far, from appearance, function, and the taste of the water, these filters are the equal to the Samsung filters. The only difference I can find is in the price. I got three Refresh filters AND two day delivery service for about the same price as one undelivered Samsung filter.
I am not cheap. But I am frugal and this deal seems to embody frugality.
If these filters, in the future, do not live up to first impressions I will amend this review.
