A power module was used. There were still bits of solder wire and flux on the power connectors. If you need new components, you can look elsewhere. EDIT: The seller explained to me that while solder and rosin marks are a bit pronounced on my power module, sometimes these just come from the factory and the unit should work fine. I measured the voltage and it works as expected. I no longer feel like this product is 'used' and my expectations for electronics looking shiny and new have been lowered. Updated rating from 1 to 4 because the product works as advertised.
