Yes, the real product LOOKS very professional but it will not work at all. I've tried both dongle mode and Wi-Fi mode; both cannot connect to the internet. It didn't even come with an instruction manual, but apparently there are many forms of this product on cheap websites. The software to run it is also very outdated. I strongly recommend buying something else.
