Query: Product sucks... but not in a good way

I should have known better than to get a product that uses suction cups. The cups, despite being moistened, didn't hold against smooth and cleaned tiles or porcelain. Couldn't even stay stuck for 12 hours.Also, the design is poor as the suction cups are located too low and therefore the rack will tilt forward rather than stay parallel to the wall's surface.Too cheap to return but hopefully someone else will learn from my experience and avoid.
