After seeing positive reviews from people getting 4k120 with this cable, I gave it a go, but unfortunately, I've had nothing but issues with it.. I got the 24ft cable..

HTPC is running a 3070ti connected to LG C9..

4k 60Hz works fine, but I get no signal when I switch to 10 bit and it won't successfully switch to 120 Hz.. Turning HDR on in Windows was also giving no signal.. Messed around with it a few hours..

Moved my PC closer to the tv, temporarily, and tried the Monoprice 8K Ultra High Speed HDMI Cable, 48Gbps, Black, 10ft that I also purchased and everything worked perfectly right away..

Also noticed the slimrun connector gets pretty warm, where as the 10 footer isn't doing that..

Works and seems to be quality cable. Thinner than I'd expected and isn't a braided cable.

This cable works well with my 4K projector as expected

I got the 65 ft version for use with my RTX 3070 and LG C1 OLED TV. So far, it's worked perfectly at 4K 120hz with HDR. While I would (of course) have loved to paid less, it's by far the best price I've seen for a certified optical cable with a lifetime warranty. Plus it works! So I'm happy.
