You know, if there was some sort of evidence posted here to suggest they do work, I would be inclined to go buy them...even if I didn't
need them, they would be useful for emergencies, and I liked idea they could be used in shipping live fish - sounds very useful.
But because of the reluctance to post even information on what they are made of or suggest how they work means there is now no chance at all of me buying them...and I would never have bought them without some kind of plausible explanation.
I mean, surely if they did work, there would be no issue with posting information on how

.
Of course, if it could be proven that they do work with an explanation as to how, I would once again be inclined to purchase.
