The holder is mounted as the other parts of the series with the upper edge in the rail, the lower sheet is then applied on the wall. For me, the track is on the plaster, including myself have a tiled backsplash, characterized my paper towel holder does not depend entirely vertically what its functionality but does not limit.
Inserting a new role goes 2-3x slight of hand, it is maintained very well by the 2 metal plates on the bars. Problems with the size of the metal plate, I had still no that used by my kitchen rolls have always fitted (Zewa and real store brand).
The tearing of leaves works well 1-hands easily, simply tear off a little more momentum, thereby it has the 2 rings rotate some resistance when rolls are not equal to the whole roll with from. Also the weight of the holder keeps him well in position, so it pulls the holder not having half off. In contrast to the lower ring, the upper but not firmly welded, of reason, but not open up to me. Since the holder is in reach of my hob, it is exposed to the impact somewhat, which is why my whole system has become a little stained, which does not look quite as nice.
