I find this rather interesting-

It's somewhat vague; but, due to the potential ramifications I'm guessing this is something no one expected.
But like any "new" product that comes to market there's always mis-marketing, mis-handling/installation, and lack of long-term studies into certain types of concerns, precautions, and effectiveness.
It's definitely news to me- I'm sure there will be (if not already) lawsuits to follow. Product liability suits are, or can be, quite interesting.
