These 2 packs of HDMI 8K cables are a good buy for the price. The construction of each cable is solid and well made, no defects and excellent quality. When I tested them on my 4k resolution PC monitor, the image quality was exactly what I expected. I don't have an 8k monitor so I can't rate performance in 8k. Overall, based on my use of these HBMI cables, I would recommend buying them based on the price and quality of these cables.
