Product review (1 stars): too bad your refrigerator is out of warranty"
Installed this (correctly) in my refrigerator.  While following instructions to do the initial flush, it blocked the water getting through.  Pressure built up and broke the filter head.  Called GE and their reaction was "oh, well, it happens, too bad your refrigerator is out of warranty".  Acted like it was not their NEW Filter which caused the problem.  Over $200 to repair.  Too bad I didn't go with an off-brand filter.
