I couldn't believe the other reviews but they were true. All I wanted was a simple device that allowed me to view TV shows from a single H T M I cable source (converter box) to two H D TVs in different rooms. The TVs need not be on at the same time. The "splitter did not even allow me to have both TVs plugged into the splitter with the power to one of the TVs turned off. I am glad it did not cost much; a complete load of rubbish.
