Customer feedback describes the cable as working well over distances up to 75 feet and notes good perceived quality. That aligns with its stated long-run use, but feedback does not independently confirm the listed bandwidth or video modes. The rating distribution is mostly five-star, with a smaller one-star share, so experiences are not uniformly positive.
