As I said on the IAEI BB, this is probably just the tip of the iceberg. We are really only catching the ones with poorly copied U/L stickers. I imagine there are more sophisticated counterfeiters out there. I am not sure how you would detect a useless AFCI since even the name brand people say testers do not work on their product. Any kludge of parts that trips when you push the test button could be called an AFCI.
