How did they know it was counterfeit?

Once you took a hard look at it you could tell that the injection molding was pretty low quality.

I also tested it. The cable was faulty and wasn't the HDMI standard we ordered.

Both are pretty good indicators that it's a counterfeit product.

Amazon co-mingles all their goods. So the likelihood of counterfeits, even in amazon basics products, is high.
