Product review (2 stars): A little loose fitting.
12 Aug 2016 - Wanted to do an updated review for this...We've now had this filter installed for a little more than 6 months...When I first changed it out, my wife noticed a difference in the taste of the water and she started getting headaches...we didn't want to blame it on the water, so we pressed on...my wife actually began drinking bottled water and the issues mostly went away, (she only drank the refrigerator filtered water occasionally) but it did seem to bother her less as the months went by...fast forward to 6 months later, and it's time to replace the filter...I replaced the filter with the second of three filters I purchased, I didn't tell my wife when I changed the filter out...the very next day, she immediately noticed the difference...she said the water tasted "icky" and that it had a chlorine taste to it...she also came down with a headache after drinking the water.  Long story short, I cannot stand by this particular water filter and I, of course won't buy it again.  I just ordered some new ones and they can't get here fast enough as far as I'm concerned.  I personally can't taste much of a difference.  I hope this next filter doesn't cause the water to have a bad taste or my wife to have headaches...we are once again buying bottled drinking water at least until I install the new filter.

original review:
the end with the grommet is just a tad small.  When I insert it into the place that holds the filter, it is not as tight as it should be.  It stays in place, but not very tight.  Every other filter I've used stayed snug in place, this one wiggles a bit.  Hopefully that does not affect filtration too much.  It's almost time to replace and I hope the 2nd of the three fits tighter than the first!  I'll likely find a different source for these filters.
