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.

    This cable is probably too short for what you need it for. You’re better off purchasing another cable. Otherwise it’s pretty expensive for what it does.

    I needed a cable that could handle 48 GBPs. It solved my problem of sound drops from sound bar to TV over eArc. My only complaint is the price, but I needed immediate pick up.
