I do not think I will lose this case if it goes to arbitration for the following reasons, He has not responded back yet to my reply and I do not think he will because he realizes that his fairy tale of a story about buying a microscope on the 44th day and discovering the problem coupled with the fact he knows that I know he bought a different brand stylus of the same type the very same day is going to present problems for him if he continues, He even states I should resell it to another buyer after getting it back, this indicates there is nothing wrong with the stylus itself just that he did not like the sound of it as much as he does the other one he bought the same day.
Not sure he realizes that him stating the item was indeed new and showed no signs of wear hurts his case rather than helps it. I never claimed in my listing that it was going to sound good or even be without manufacturing problems, I only claimed it was NOS. Hence it is as described.
This is why there is a 14 day no questions asked warranty on these types of items so if there is a manufacturing problem or other issue a buyer can return it without risk or concern. I don't test these out with a cartridge and TT because if I did they would no longer be NOS but lightly used.
