Product review (4 stars): Seem to be well constructed
Can't really know for years if these are good, but they seem to be well constructed and installed just fine.  I had just helped a friend install some metal braided hoses and those required a lot of tightening to keep water from leaking.  These seemed to require a normal amount of tightening.  I think I went 2/3 turn past hand tight and one wasn't leaking so I just tightened a little further and they've been fine for months.
