I also purchased and review Product Number 10770. I prefer PID 3961 passive cable for compatibility, but the size, weight, and limited flexibility could be a problem with some installations.I tried several cables and few will support bandwidth required for UHD/4K@60Hz@4:4:4 color. Both of these products did for my setup, but PID 10770 wouldn't work with my TiVo Mini for unknown reason.
PROS: Works well with both TiVo Mini HD 1920x1080 and PCwith NVIDIA GTX970 HDMI2.0 to LG 46" UHD/4K 3840x2160@60Hz@4:4:4Color!
CONS: Thick cable, heavy, with limited flexibility, with large connectors.
I guess it's a good cable that should last you for years. In my case it was impossible to use because I couldn't fit them in the designated space. Also the HDMI connectors would disconnect very easily because of the rigidity.
I guess I should have read more carefully the technical specifications to understand that it was a fat cable to avoid wasting $20 in shipping both ways.
PROS: The cable itself seems to be bulletproof so it should last you a very long time inside any wall.
CONS: Very thick, double check that it can work for your setup if you're considering to channel more than 1-2 cables through the same space.
Very rigid, making it difficult to follow any curve, also the connector seems to be too weak for the cable.
