Unfortunately, first worked no HDMI CEC

Property me thus total 8 2x cable bought, actually I had only 6, but substitute one can use always. So offer came just in time. Unfortunately, no cable works HDMI-CEC. ARC I then not even further tried.

Otherwise the cables are quite okay, especially the fabric sleeve makes a high-quality impression, but that's no matter because I can custom cable, the HDMI-CEC.

EDIT: So the support was faster than I could ever write a mail and I quickly receive a replacement. Cable now work without problems and Preist / power I think there is nothing better.

I can recommend the cable only every warmest. Unfortunately, I have no equipment with HDMI 2.0, but really it would create that too.

Thank you once again for the quick and straightforward support.
