We aren't 'afraid' to use them, 1974CB, we just refuse to be suckered in to buying something that we, personally, can't see working. I'm also offended by dynabeads marketing tactics.
Again, I will buy these before Christmas, and have them tested on a wheel balancer.
I'm not trying to dissuade you, or anyone else, from buying and using them.
I, personally, have a natural tendency to study and evaluate claims and issues, with as much knowledge as I have, or can find.
I also prefer to follow practiced, scientific methods to prove or disprove a claim or theory. Anecdotal evidence and bad math are not acceptable to me, nor are unscientific methods of data gathering.
Me 'trying' them is an unscientific method, as I know that a.) I am incapable of measuring minimal (or nonexistent) changes in a complex system while being able to ascribe said changes to a single element of a complex system with multiple elements and b.) I am already predisposed to believing they do not work, which could color my perception, and therefore report, of the item in question.
Also, any claim I made would also be anecdotal, which is unacceptable. Without the use of a calibrated measuring system, that gives me quantifiable, repeatable results, I cannot make a claim as to it working in good conscience.
