Review on RUIPRO 8K HDMI Fiber Optic Cable CL2 Rated 25Ft HDMI 2 by Jeffrey Connel

Update: I couldn't contact support but I replied to their automated email from Revain and they told me it was a problem with the initial wiring. They have since sent me an updated version and it has been working great for over a week now. The updated cable has red and green lettering on the connectors. If you receive one with gray lettering, it is an old defective one. Same problem as others here. 4k keeps crashing at 120hz. I'm assuming it's a bandwidth issue as the short cable that came with my Xbox works fine.
