Good reliable active optical HDMI 2.1 cable. This was purchased to replace a passive cable of the same length that was experiencing handshake and stability issues, I now have no issues. Very happy with purchase, can't beat the price!

Good quality and does the job without causing problems on a long cable run.

The cable seems to work overall well I can do 120hz 4K 12bit RGB but I am sometime having issues with the EARC. I sometime randomly get static sound out of my output. But when I switch the audio and come back it works. I did try and reach out to support but they seems to have gosted me since it’s been more than a week since they told me they forwarded my video to the technical team and I haven’t received any follow up. Here’s the video that I sent to them https://youtube.com/shorts/cDe8oOkBEp0?si=yvK4w_9pSP9bCRLP

Product works as described, great price!

Curing radius not the best, it works as hdmi 2.1

This cable does not meet HDMI 2.1 standards. Does no have enough bandwidth to output 4k@120Hz.
