Review on avedio links 196ft HDMI Extender Over Cat 5e/6/7 | 1080P@60Hz | 3D Support | EDID Copy | Deep Color | Single POC Power Supply by John Destruction

Advertised for efficient A/V transmission up to 196ft over Cat6 and POC cables - only one power cable required. I have a 35 foot run from the Roku box to the monitor. The image flickers and turns off intermittently. 2-3 minutes is fine. Then it goes off every 5-10 seconds. I will be ordering another power supply to attach to the RX end (which is advertised as not requiring a power supply). If this doesn't solve the problem, I'll send it back.
