I originally bought the 10ft version of this cable, but it didn't take long enough to climb through the wall to the exit. Until I was able to send it back to Revain this product worked great. I just received these two 16ft HDMI 2.1 cables and they are great. (since 4 days) If you are looking for high quality HDMI at a good price that supports the fastest speeds across the board then you have come to the right place. The sheath around the cable is strong. It works great and breaks through my wall by about 11 feet. No delays or signal loss at the moment. I had a problem with my old cables that supported 4:2:2 chroma subsampling on my Apple TV through my 4k Samsung NU8000. I took the risk of buying a half price Newegg cable, which was super fast at 48 Gbps, but the screen kept flashing for about 4 seconds every 30 minutes. Strange. I'll update if anything changes about this product, but based on the research and testing I've done, for now, don't buy super expensive cables and don't risk super cheap ones. I've reviewed Newegg, Monoprice, and pretty much everything in between. You need that. And yes, it's backwards compatible as my TV only supports HDMI 2.0, but this cable works with no issues. Great company to buy. I will definitely buy from Zeskit again if I need more of these cables.
