Review on MavisLink 35ft Fiber Optic HDMI Cable | 4K 60Hz HDMI 2.0 Cable | 18Gbps HDMI Cord with ARC, HDR, HDCP2.2 & 3D | Ideal for Blu-ray, TV Box, HDTV, 4K Projector, and Home Theater by John Greene

Firstly the price, secondly the quality of the product as described, thirdly the 100% signal transmission, which is what we value most when buying a cable. With fiber optics, even at a relatively short distance, you know that when you operate your multimedia devices you get 100% guaranteed video because it is literally carried by the mirror along its entire length, so no loss, so if you want to calibrate your TV picture, it It's good to know that you provide 100% of the signal before launch. No copper cable can do that over many distances and even better over short distances! So I think it says everything is well designed and WORKS.
