Product review (5 stars): Actually makes a difference
Like everyone else, I HATE that we have to buy these stupid expensive filters for our fridge, so I put it off as long as possible.  When we changed it out this time, it had been about 16 months, and wow, what a difference.  I was skeptical that they even help, but we are glad to see the black/white comparison so clearly.  With that said, we have been using the new filter for about 2 months and I can already tell that the taste is changing from "wow" to "still better than tap".  Somehow I doubt I will be satisfied with the taste at 6 months, but will suck it up anyways to delay having to buy another one.
