Summary: This set is advertised and sold as a 12 volt HDTV. It does NOT come with a 12 volt power cord, only a 120 volt ac adapter. I purchased this set for use in a motorhome and/or boat. Have not been able to find a 12 volt power cord for this set. This set is expensive compared to other 120 volt HDTV's of this size.
Summary: The picture quality on the unit seems to be ok, but the sound quality is terrible. I thought something was wrong until I saw another couple reviews that said the same thing. If you try to turn it up at all, or turn on some bass... it just distorts like crazy. I ended up connecting an aux sound source in order to tolerate it.
