Long story short I bought this for a wedding using a brand new 150ft Cat6 cable (200ft is listed in the product name and packaging). When the transmitter and receiver were finally connected (solid blue light), the video ran for about 15 minutes (during the test run). It stopped working when the ceremony started and then started flashing (the video itself, not the status light). I think it's partly my fault for putting too much faith in such a cheap device. A decent number of people say it works very well for them, so maybe mine is defective. Although I can't trust it. Other HDMI extension solutions used at the same time worked as expected.
