Hi, Scotty here - the guy that made the video. bspn pretty much nails it. I don't really know for certain, but I think a lot of the parts are used/refurbished from original iPhones, with a couple parts that are really good copies mixed in. Everything is pretty top notch quality as far as I can tell though.
