A significant portion of the market is flooded with counterfeit or "clone" Delphi DS100E devices. These are produced in China with cheaper, often faulty components to mimic the original tool. This leads to problems such as fake FTDI chips (which lack an EEPROM to store settings) making driver installation problematic, incomplete circuit boards with fewer relays affecting compatibility, and missing or emulated proprietary chips (e.g., OKI m6636) designed for specific protocols.
