Product review (1 stars): missing parts
I have used this filter in the past and ordered two replacements.  This time, however, I was sent the Culligan IC-100A instead of the Culligan IC-100.  The difference is, as I can clearly see on the boxes, the A does not contain the two fittings (adapters) that I need.  Make sure that you receive the correct product before you put this away for future use (as I was going to do.)  My order and my receipt both say IC-100 (no A) and since there doesn't seem to be a way to directly talk to Amazon or e-mail them, I'm just returning these.  Problem is that in searching for the correct product on the internet, all links go back to Amazon -- the Amazon cosmic loop.
