Product review (2 stars): Good for two months.
At first, this filter worked great!  I had no issues with leaking at all.  Stream was strong and clear after you ran the loose carbon for a few gallons.  Problem is, after a few months of only light use, the stream diminished to the point that it's unusable.  I thought that maybe there was some junk in the lines (we had just moved in) so I replaced the filter.  Same initial experience - worked great!  For two months.  Second filter also diminished very quickly.  Problem was, NOW I had a whole-house water filter/softener - so the lines were absolutely clean by this point and the water coming through was pre-conditioned.  I don't really need a filter any longer, but I can't NOT have one and still use the convenience of the water spigot on my fridge.  Replaced the second one... same problems with the third.  So they get a second star for the price and initial performance... and lost 3 stars for life span.
