Once opened, we realize that the case is much smaller than the amazon image suggests, but it is anything but a problem! The active splitter works flawlessly. I use it to an input signal splitter a Playstation 3 to TV and the other end to a PC capture card and am very satisfied (so to speak, I saw no difference connected between the live and via the splitter playstation, it seems to me such simply). Good news, then, with me the quality is not at all altered.
Or, if you need a splitter that carries sound, hdcp and all other standards without altering the signal, I advise you strongly, even despite its price (relatively expensive for the end a little box filled with wires )!
