I bought this cable to connect my PS3 after a bad experience with a similar cheaper cable. Despite popular opinion that all HDMI cables give identical picture and audio quality no matter what the cost, this cable really does deliver.
The handshaking process with the cheaper cable took several seconds whereas with this one it is instant. Not only this but I noticed smoother picture quality and the colour banding, that was present using the cheaper cable, had all but disappeared. I hasten to add that I was testing in 1080p high definition.
From my own experience, cables like this can and DO make a difference to picture quality, if only in high definition. In addition, better quality cables don't have to be expensive... this cable is proof! BUY IT!!!
