Product review (5 stars): Perfect Fit
I removed the old filter, opened the box and put the new filter right in....it couldn't be easier.  This filter even came with a little sticker to tell me when it is time to replace it again.  Although, what happens if you don't replace it?  It was 2 1/2 years since the last time I replaced my last one..... previously I had to pay over $50 for a filter.  I will say that there is less sediment with the new filter, but no difference in flavor.  For me, it's the flavor that matters.  So, will I be more timely in replacing my filter?  Only time will tell....
