Two of these control cables in the bathroom and I also use two on the floor around the TV/system to hide unsightly cables where nobody goes. You don't need all the tape - just cut three squares on each end and in the middle for easy removal if needed. I installed them upside down in the bathroom so they don't collect water or "things" and so it was important to first insert the wires and then install them, but I think it would have worked either way.
