The product doesn't work. I've checked my outgoing HDMI cables and when each is plugged into my computer, it works but then when I plug them in to this device I don't get green lights. I also checked input HDMI cable, it works and I get blue light. I'm giving it 1 because manual said that if I don't get green light it's due cable lenght (mine are 2m) and the max length was never given in product description.
