I'd rather be buying a product and at least know it was a copy, than buy a product that was a copy and never know about it.
Although I'm sure it is, for things like your RPS clutch, you now have to hope it is actually an RPS clutch, and not a CZP clutch that he put an RPS badge on.
At least with a little research you would know AMS was ripping someone off, and at it wasn't the consumer because you'd still get what you paid for. All legal things aside this is still far worse as CZP was ripping off the consumer and the inventor.
