Product that seems solid, but beware of walls on which you put it, mine is painted and at the first use it has left visible marks round. There is no protection on the ends and it is the metal itself, which comes to rest against the wall. To overcome this, I put a piece of cardboard end at each end, attached to the bar with the large scotch: the bar still stands as well and does not leave any marks. To ask is quite simple, they are rotated each end of the bar (one after another) to increase or decrease the length of the bar, and once the desired length almost reached, the place the desired position and turning the center of the bar, which has the effect of increasing the length of the two sides and attaching it.
