Review on 📶 High-Performance Wireless HDMI Extender: 5GHz Loop Output Transmitter and Receiver for TV/AV, 1080P 60Hz Full HD with IR Remote Control - 656FT Transmission Range. Ideal for Projector, Monitor, Church, Office, Home! by Joseph Quintana

About a year later I had three of these TVs. Exactly a year later, the first stopped transmitting the sound to the second TV. Nothing but intermittent squeaky noises. Nothing like the sound of what's going on. The second stopped sounding after about a month. The third did not transmit any sound at all right out of the box. Although the picture is great. So yeah, shame on me twice. for customer support but they don't bounce your emails back. So there is no CS support. And the issue is just too technical to support a Revain product. Be careful buyers. It works for some and doesn't work for others.
