The Chinese vendors sell counterfeits of many products and they tended to be substandard. Today, quality of the various counterfeit products vary widely, and though same may seem well made, the quality control varies. There are cultural differences between the US and China and the concept of intellectual property (IP) is very different. Where many here see IP copies as theft, it is seen as a sign of respect by many that make the copies, as they adopt the better design. Sal even brought this up in an interview as he discussed a visit to a Chinese factory. Of course, the consistency of these products vary and materials are commonly not what is sellers claim.
