This happened to me with a Steam Controller. Ordered "Ship from and sold by Amazon.com" and received one without retail packaging and accessories and was defective. Had no issues with it getting replaced by Amazon. I assume some sellers use FBA to let Amazon deal with customer service so they can get away with selling bad products. Really wish they wouldn't mix SKU and stock. Perhaps its cheaper for them and if the customer notices they can replace it and still come out ahead. But it doesn't seem fair for someone who can't identify a fake product.
