Anticables

What madavid0 describes is commonly known as BUYERS REMORSE!!! You have not been scammed! Here's how life works: If you buy something and don't like it, and it is within the return time frame, you return it for a refund; if it is outside of the return time frame you sell it on.

Anti Cables and its owner Paul Speltz have a sterling reputation for customer service. Did you even bother to contact them before trying to smear their good name?
Smear  /verb
2.damage the reputation of (someone) by false accusations; slander.

chrisr, It is only a scam if the manufacturer either does not deliver the product at all and keeps your money or refuses to honor their written return policy, neither appears to be the case here despite your own personal bias.

Jif peanut butter: Scam?
I bought a jar of Jif peanut butter for $2.89 and a store brand of peanut butter for $.89 and the store brand tastes the same, maybe even a little better! There is obviously no reasonable way that I could have even suspected this before trying them but I will not return the Jif and get my money back even though the store allows it.

I appreciate that you want to approach this from a scientifically factual basis. In this spirit I will point out that your opinion is not scientific fact, it is simply your opinion. I would be more than happy to look at any scientific data that you have in regards to Anticables making false claims. The term "scam" has a legal definition which both you and the OP are not using. The way in which both you and the OP are using the word "scam" is in a subjective and biased manner which does not adhere to its legal definition.
The OP purchased a product with the ability to return it and get his money back which he has not chosen to do at this point, that is the only verifiable  fact.
