I think it is all about cost, I don't think there is ever enough effort on product information on low cost manufacturers. It is a trade-off. They most probably buy a generic unit from a manufacturer then rename it and provide basic information (They may not even know the difference). There are a lot of consumers that are not interested is detailed specs and that is where they get their money from. People like you and me try to track down relevant information and spend a lot of time to see if the price is worth it otherwise give-up and buy a more expensive unit with detailed specs.
