"Micro HDMI to HDMI Flex Cable" doesn't really match the specifications described. If you need video and audio output from your device (I have a 4k mirrorless camera) this doesn't work properly. No audio is transmitted over the cable unless video is also active (think muted video on a zoomed call). The cable does not properly transmit UHD30FPS or FHD60FPS, which is what is expected of a "high-speed" 18Gbps cable. When purchasing this cable we thought Revain would have QA for their own brand but I was wrong. This is another of their branded products that was launched without proper validation before it was given its name :/
