Product review (1 stars): DEFECTIVE!!!  Broke in less than an hour.
In an attempt to save a little money (those GE brand filters are RIDICULOUSLY expensive), I bought this Water Sentinel filter.  When I installed it, it clicked into place and appeared to be working just fine.  About an hour later, I hear this loud "CLUNK" sound coming from the direction of my fridge.  As soon I open the door, a waterfall comes rushing out all over my kitchen floor.  And there is water spewing everywhere from the back of the fridge.  The filter had actually broken and fallen off.  All I can think of is how lucky I am that I was still home at the time of the incident.  And how I should have avoided all the hassle and just paid for the GE brand filter to begin with.  At least I've learned my lesson...
