I bought this so we can have hybrid meetings in our conference room. I used a shielded Cat6a cable, about 60ft, I have no problems with 4k quality and sound, but I did have problems with the USB ports. I was only able to connect 1 camera to the extender's 4 USB ports. That's why I give minus 1 star. I had to buy another USB extension cable which cost me $65 so I could connect my second camera. I contacted tech support and they recommended trying a second power supply for the receiver, but I already have a USB extender and it's all set, so I haven't tried that. Maybe I'll do it in the future just to see if it really solves the problem. That being said, if you don't have the same needs as me then everything works fine.
