Sean, IMHO you are not wrong. I've a good friend who is an astro physicist (he is a dept head at an major University and is a consultant for NASA). Even though he is not involved in designing devices used for controlling resonances in electronic components, just for the fun of it I ran this by him...he admits that he is baffled by the manufacturers claims. As you point out these claims can be proved by carefully controlled testing. If these products have merit the testing will support it, if not, all of these promotion materiels and testimonials are nothing but "gas light". We'll see. The ball is clearly in the manufacturer's court now.
