Stability is also given in principle.
An error has crept in, however in the design: One of the screws (for the toilet paper holder) can not perpendicular with respect to the base plate are screwed, thus the screw head extends much further towards the bottom, which is compensated by the rubber feet not quite. I have repeatedly tried to screw it vertically, which can be replaced by the bar but not to. The problem: metal screw is in contact with the ground, with tiles in the bathroom can end badly by careless handling. Grinding of the screw head or a piece of felt or equivalent standard glue.
Second deficiency, but not so serious: The brush handle is screwed consisting of several parts of the brush and the gland sometimes becomes loose, because you have to give a bit more careful brushing and apply rotational movements in one direction only.
