Recently many customers responded to us that they got the notice" The number you are checking does not exist. The product is not made by FiiO Company" when checking authenticity on our website. That's because our supplier was transferring data to other server. We're really sorry for the inconvenience it caused. Now the system has resumed function, authenticity checking is working fine. Feel free to check your product on http://www.fiio.net/en/fiio. Or you can contact firstname.lastname@example.org for any other problem.
