Just caught this thread, interesting!
Just heard back from the seller. He does not want to offer a refund. He figures I just don't like the cable, so I can simply resell it. I told him that the problem is the cable doesn't work as it should. And therefore, I can't resell it, in good faith.
I also suggested that if I send it to Cardas and they determine it's faulty or fake, then I'd have to pursue a fraud claim. Although, that's probably not gonna bear much fruit. So I asked him again for a refund, and offered to cover the cost of return shipping. We'll see what he comes back with. My guess is he won't comply.
I'd send it to Cardas, as many have suggested, but my gut is that it's not counterfeit, but rather, old, and perhaps damaged in some way. And by the time I pay for shipping, validation, re-termination (assuming it's okay...which doesn't make sense, given its sonic signature), shipping back, duty/taxes/brokerage fees etc -- just so I can resell it -- it's doubtful if it would be worth my time.
It's tough for us being across the border- I bought a cable and recently returned it direct from a manufacturer with a 30 day return policy, and it still cost me over $100 in shipping/duties/taxes, and that is with them substantially de-valuing the product for customs purposes! There must be a way to claim the taxes back if it is returned, but is it worth my hassle? There wasn't even an option in the customs docs for "returned product" so I checked off the "warranty/repair" option when sending it back, so hopefully there isn't another broker charge on their end I will have to pay for as well.
I am curious as heck to investigate who this might have been you purchased this from- shows pretty bad if you are confronted as possibly selling a counterfeit product, and not giving someone their money back. Myself, I would absolutely refund the money and take the product back as opposed to having that bad feedback and not being able to sleep knowing you ripped someone off, whether it was known or not- but from your response above when the person was confronted it almost seems like they knew. If they said "just resell it", essentially pass the problem onto someone else, that shows alot about their integrity, or lack of it. For sure I would follow up with this person if it turns out to be a fake, and provide the necessary feedback so the next purchaser is made aware of that possibility from this seller.
Update us when you hear- I am dying to find out!
