I'm guessing the unit I got on \"sale\" was actually a refurbished model, but it still works so whatever. The unit was scratched and marred, had dirt/grease (not packing oil), and some loose shavings but it works and for the price it's hard to beat vevor products. I did mark it down one star for either deceptively selling me a refurbished unit OR for having such poor quality control that the units ship out like that. I would gladly purchase more VEVOR products though. Harbor freight quality, won't last forever, but for niche things my life doesn't depend on they will do the job just fine.
