I don't own any 3D equipment so I can't vouch for its performance at high speeds.
That said, it works very well transmitting 1080p video and audio to my Samsung TV from an Onkyo TX-NR609. The Audio return channel from the TV back to the receiver also works very well (once I'd plugged the cable into the correct HDMI port on the TV - doh!)
The cable itself has solid feeling metal connectors on each end and the cable is quite thick (good as it should be more durable) yet still flexible.
It was more expensive by a few pounds when I bought it so it's even better value now. Highly recommended
