First of all this cable wasn't a premium product but it still arrived within 3 working days so thanks for the fast shipping! As for the cable itself, I have a 20 foot cable that has very good build quality. The ends are well reinforced and the cable itself is nice and light. My 4K setup with HDR works with no issues, stuttering or lag. It is directional thanks to the Redmere chip. They have a cable on each end that we'll identify, but just make sure you get it right when installing. I have seen cases in the schools I have worked with where the Redmere chip would not allow video to be displayed when connected the other way round. No idea why, but it happened. So just pay attention to the installation. I connected it to Samsung Qled and it works with my Elite 91 receiver. I connected all my devices from there. Everything switches back and forth with no problems. This cable is worth the money and I will definitely buy it again. I've only had it a few days so I'll update this review if anything changes, but I doubt it will. It also comes with a lifetime guarantee. So if there is a problem, I will also see how to do it. But so far I'm a happy customer.
