Product review (5 stars): Far superior quality for only a little more than plastic.
The line from my sink to the ice maker/water line runs down through a crawl space.  When a rodent chewed through a plastic line, I replaced it with this one.  I just pulled the new one through the crawl space from above by tying the old one to the new.  For the money, this one is hardly more expensive than the plastic, and it a way higher quality.

When pulling the refrigerator out for servicing, I can't imagine having the easy to crimp plastic line any longer.
