Don't know anything about the Prolectrix USB Radio TV Dongal, but I do own a USB Internet Radio TV dongle with no actual name, which I suspect comes from the same Chinese factory that many others including similar branded products come from. I got mine from eBay for £4.99 a few weeks or so ago.
Haven't tried it yet, but on asking in this forum, I seem to have had various responses as to the function and reliability of these devices. But they are supposedly able to provide 38.000 Worldwide Radio and 18.000 Worldwide TV stations via an internet connection, and most Windows platforms.
Hope that I am not getting confused with some other product, so making nonsense of the above?.
