I am using 4 of these cables to chain my components (Apple TV 4K, 4k BluRay player, Dish 4K Hopper 3 Receiver, and Xbox One S) to an Onkyo receiver and then using the high Speed HDMI over Optical to my TV (30 ft run). All signals are pure and clean!
This cable does as advertised. I am currently running 4k at 60Hz through it and cannot believe how thin the cable is. I would be careful not to kink it or make too sharp of corners since HDCP loves to flake out on HDMI if the cable make too sharp of corners (and this wire will bend as sharp as you make it), but so far I have had absolutely no problems at all with this in 3' or 15' lengths. Also while extremely thin insulation, I have not had any perceptible interference from the many other cables running to and from the same source.
