I have the 8m version of this product, it provides the full hdmi experience and even the 8 metre version is very long and handy for me. The product has a protective layer which is woven, the material it is made from I do not know, but it has survived for more than a year being constantly inserted and removed (several times a day since I use it with a laptop)
Your not likely to have a problem with this product, it'll likely last you into the days where hdmi is a primitive video input method, similar to how scart is now! Hehe.
