Civil torts for defamation involve calumny, libel or slander. All three of these have two things in common; that they are lies and that they have malicious intent.
If you see anything in this thread that is a lie on our part, please point it out to us. We have, for our part, pointed out aspects of the product in question that are measured by professional instruments.
If you are distressed with the outcome of those efforts, then I assure you that the cause does not lie with us, but more likely with you. Jim
