It prob is an excellent product and it's possible others may know already but I was rather surprised at the thickness of the DVI-D cable. I guess it's because it's for in wall use? Just be aware. It's thick!
Absolutely get this. I'm using it to put my PCs in another room so my work area is dead quiet. Even at 1080p 144Hz there is no noise or 'sparkles'.
PROS: Does what it says on the cover. Beefy ferrite chokes to keep noise out.
CONS: The bend radius is poor so you might need a right-angle adapter to make the connection to your monitor if space is tight. The thumbscrews are made out of a rubber-like material so you can't screw them down with a screwdriver.
They work! I tried to extend the length of my monitor cables using Displayport cables, what a joke that was. The only way to get displayport to work over any distance is to use an active displayport to dvi adapter and then use long dvi cables. These are perfect, high quality, thick cables.
PROS: high quality, thick cables
CONS: Thick cables. These cables are big, but if you want to send a signal over a long cable this is what you need.
