This product makes me think these scart Strip that existed and still exists I think that do not have mute buttons, suddenly if you connect several SCART sockets on the strip the signals are mixed and it makes a nice edge ... ... Here is a little similar except that it relates to the signal. Indeed this little wonder is not validated HDCP (HDMI mandatory protocol) so when you connect an HDMI signal which is the purpose of this decision by your image lollipop .... It's great to market products that do useless. Well it's cheap so we made a cross on it instead of bitching. So I will recommend another outlet but this one with HDCP
