I don't know what the negative feedback is. One reviewer said these cables aren't 4K. That's a pack of bulls. They are clearly 4K and support both HDR formats HDR 10, Dolby Vision and HLG HDR. I love thin HDMI cables over thick ones because I have a little holder on the back of my TV that holds all my HDMI cables and keeps clutter out. This is another plus of these cables. Buy them, you won't regret it!
