Review on HDMI Cable 4K Ultra HD - 100ft (1 Pack), Nylon Braided HDMI 2.0 Cable: High Speed 18Gbps, 4K@60Hz HDR, 3D, 2160p, 1080p, HDCP 2.2, ARC, HDMI Cables for Monitors and HDTV by Jill Kohlmeyer

Note I'm NOT using this in a 4K system! I bought this HDMI cable to connect my Pandora's Box type arcade controller to the back of my home theater. so it can be played on the home screen like we're used to from the slot machine days. Since it only supports 1080P, it works well. The real value is in all the extras it comes with, TONS of different sized zips, wall mounts, HDMI L adapter. And 50 feet was more than enough (I had about 6-8 feet left). The cable is quite thick and very durable. I'm very happy with this purchase, but I have to reiterate that I haven't tried it at all for 4K.
