But is it legal?

YES! Definitely. It is completely legal to use as you are not saving the content just streaming. That is the great thing about it.

Of course cable companies are not happy with the situation so they are trying to stop TVFrog from selling it to the public. So it might get banned soon, but as soon as you have one you are completely fine and will be able to watch everything for free forever - completely legal.
