Customers are saying

Customers consistently note the excellent picture quality, reliable HDMI connectivity, and good overall performance. They also appreciate the variety of cable lengths and fast speeds. However, some customers find the product to be on the higher end of the price spectrum. A few users also mention concerns about cable flexibility and compatibility with certain monitors, though lag is rarely reported as an issue.

    Not for use with Xbox Series X (4K @120 FPS). Experienced brief periods of signal blackout which did not occur with the high speed cable accompanying the Series X. This brings into question its claim of 8K @ 60 FPS. Solid cable otherwise.

    Nicely shielded and the cable is quite durable. Nowhere near worth the asking price unless those two perks are more important than Justin Bieber's latest hairstyle. #belieber

    Not sure if I do see much difference. I got new Sony Bravia A80J - 65" Maybe need more setting, will take some time later and try to see if 4K difference can be obtained at max.

    You're better off ordering a cheaper cable, just look for the 48 gbps certification when shopping. There are some cheaper cables at best buy but not many support 8K.
