I took a tour of a company where they build machines like this last year, it's amazing. One guy was telling about a customer who bought several machines from them, then buys rejected products from big manufacturers who have less sensitive machines, and find the good product out of those rejects and sells that again. Almost literally finding needles in haystacks, and making money from it (and reducing food waste). (not sure if the guy was supposed to talk about this, so keeping it vague on what the product was)
