Review on 📶 J-Tech Digital Wireless HDMI Extender 1080p – Extended Range up to 660 ft, Transmitter & Receiver Kit with Selectable Frequencies, Minimized Interference, and IR Remote Control (4 Sets) by Bruce Marable

I bought a transmitter and 3 receivers. These were models that had to walk 200 feet. They wouldn't go 40 feet in my one story frame home. The signal dropped every few minutes. I paid to upgrade to a JTECH-WEX660 which is said to have a 600ft range and I still get frequent dropouts. I don't live in a Faraday cage, but in a simple house. I worked with their tech support for over a year and they couldn't solve anything. The transmitter also freezes a few times and needs to be disabled to restart it. I have a lot of tech and this is the worst purchase I have ever made.
