Product review (2 stars): Poor quality assembly makes me suspicious of the contents
While they're posted as a direct replacement, they aren't.  The business end which mates to the refrigerator water fitting is similar but has several differences which prevent it from locking in properly.  The alignment between the end cap and the handle is off by about 15 degrees.  Therefore it looks crooked when installed.  No leaks though.  Poor quality assembly makes me suspicious of the contents, but it seems to be working OK.  I probably won't purchase again.  It was supposed to be a Prime delivery, but took ~3 weeks to be delivered.  I'm not renewing my Prime membership.
