I needed to run HDMI cables from a mounted TV, through the wall and back up to the cable box. So, the lengths required were very long. These did the trick. The picture quality on my 4K TV's fed by a service provider with a fiber optic network was less than expected, but still very good. The connectors themselves have two areas of concern. 1) the strength of the actual connector is not great. One bent when the TV was repositioned and became inoperable and had to be replaced. 2) The connector size makes it visible when plugged in top HDMI ports on the sides of the TV as it extends a few inches before it can be 'bent' to hide it.
