SiberiaProg's main advantage is its focused reliability for specific tasks (especially 93C EEPROMs), its lightweight and fast nature, and its simple multi-threaded operation. In the Full version, go to Settings →
One of the biggest risks with cheap programmers is voltage incompatibility. Many modern flash chips operate at 1.8V , while older chips operate at 3.3V .
Run the software in a Windows Sandbox or an offline virtual machine if you are paranoid.
