There's no way to report a counterfeit on Amazon unless you're claiming a violation of your own IP rights. I've complained about fake solid state relays. There are lots of fake "Fotek" solid state relays. UL has noticed.[1] The fakes are usually marked with much higher amp ratings than they can handle safely. Look at this "100 amp" fake "Fotek" relay on Amazon.[2] Fotek doesn't even make a 100 amp relay in that packaging. [3] 100 amps requires bigger terminals.
These things tend to fail into the ON state, which is not good. Or they melt down or catch fire under full load.
