Invisible Wiring Solution by DeCorp?

My local audio dealer gave me a sale-sheet on this product. It is very thin (.004-.014" thick). Their web site shows amazingly easy custom-installation solutions.

Does anyone have any experience with these. While I'm sure they work, I wonder how they compare to more traditional in-wall cables.

I have installed them in my living room - flat speaker wire for 5.1 surround sound system, with their banana connectors. It was an under carpet installation.

It was easy, and it does work great as far as I can tell! I wouldn't have bothered with a home theater if I had to start drilling in the walls ...
