It works much better than the Mediabridge cable I replaced. Hand tested, HDMI 2.0 ready - UHD, 18 Gbps, Audio Return Channel, Ethernet). The Mediabrige cable has not been working for 5 months. I contacted customer service about the warranty and they told me to send it back, wait for it to be checked and if the warranty is applicable they will send me a new one. Missing or will be serviced within a week or two 3- Warranty is basically a gimmick 4- I've bought a lot of cables over the years because I'm in the entertainment industry. Most companies will send a replacement first so you won't be out of service and will either give you postage prepaid to send the defective unit back or just tell you to throw it away. Mediabridge does not do that professionally.
