My only regret is not having discovered this system and this earlier! Lives rental, I did not drill, but had previously not find strong enough to support system shower gel, shampoo and other. Well it completely fills his contract! After misplaced once I wanted to reposition it, and I have done it without problem since it cleans well and the cup holder! So great for awkward (like me) or undecided. Installation is very easy: you can withdraw the suspension to attach the suction cups that come with a kind of "syringe" to draw air and adhere the suction cups. And after a few months and this obviously takes good! Knowing that I up 4 or 5 shower gel and shampoo. Only complaint, the spacing between the upper floor and the lower floor is not large enough to accommodate large format bottles (500ml) vertical.
