Convenient and easy to use. It is a flexible sheath in which store all the cables running, to become one. even if you want to put 4, 6, 8, 10 ... It does not matter: it goes! Of course the more you put cables, the more you lose some centimeter over the entire length. But honestly, lose a few centimeters and 10 meters sheath, and have more than a cable across a room ... it is priceless! ^^
