Product review (1 stars): Cheap plastic parts
I bought a two-pack for my Sub-Zero refrigerator.  The older water filters used to come with brass nuts on each end but these new ones come with plastic ones.  I over tightened and cracked the first one.  This is probably my fault but would not have happened with brass nuts.  Luckily, they come in pairs, so I installed the second filter without any problems.  Next time, If I have a choice, I will choose a filter that is made with quality parts.
