sucker fails

I tried once, twice ... it is clear that it will not hold !!! because the goal was to hang the brushes for electric brush, for now I'm using box ... after the holidays to do if I do not try to put double sided tape or other adhesive ( but I have really wanted to avoid, precisely) ... :(

ah, and then and more sites are too narrow, the brushes do not fall within (pdt 2 max when the contraption remained sucker to the wall), so they are just dangling over, held in place by the blue cover .. . re-blah
