First, I have to go what are. CSL has a Super Computer Support! Have 13 months ago bought at CSL an HDMI cable which now was unfortunately defective (no sound transfer). Can occur even once. After contact by e-mail with the CSL team me a new cable was sent within a few days. Contact with CSL was very pleasant !!! The cable I can say to the defect was 100% satisfied, class picture and sound transmission. But as I said, a defect may occur even once. Will gladly buy again at CSL. 5 *****
