Worthless. Worse than worthless, snake oil. HDMI and DVI are digital cables. Digital cables suffer zero signal degradation under normal, semi-normal, and all-but-totally-out-of-spec conditions. If you're running less than 12 meters you don't need special cables, you need any cables. Cheap is exactly as good as gold coated oxygen-free unobtanium-137 cables.
Now what we've got here is a claim that they're 'enhancing' the signal. The only thing they could be doing is amping it, since I doubt they're breaking the HDCP encryption, running a sharpening filter on the video data stream, and reencrypting it. And if they were you would not want the cables to do that you'd want your TV or your one of your expensive components to do that (maybe). So they're amping something which doesn't have any degradation anyway, so the stream of 1s and 0s arriving at your TV is BIGGER 1s and 0s, which decode into the EXACT SAME datastream as it wold have with a generic $10 Vaster cable.

“An engineer explained to us that hundreds of ear impressions were gathered in the name of research, and while each one obviously boasted its own unique shape and size, one single characteristic remained uniform across the board: the entrance into the ear canal is not a perfect circle, it's an oval.”
