MiraBox HDMI Powerline Extender HD 1080P Deep Color & HD Audio with IR Remote Control Transmitter up to 984ft over home power line

The units themselves look of very good quality with their metal casings but I'm after that's about all the positives.I didn't like the bulky 2 prong to UK plug adapters. I think they should be supplied with the correct leads. Also the rubber sides/feet fall off too easily. Minor niggles really.Initially I hooked up the units to a Sony TV. Whilst the picture looked okay the sound was really loud white noise and no actual audio from the source.I tried a different TV and got audio. Unfortunately I also got a poor picture, audio sync that became probably 2 seconds out, occasional picture breakup and occasional blasts of the white noise especially when changing channels.It's a shame because this unit was so close to being okay, but the issues just got worse to the point it was unusable.Maybe there's just too much noise on my ringmain and it may we'll work great for others.I've since replaced it with the Mirmatek HDTV Anywhere and so far that's performing perfectly.
