Review (3/5): It's okay
The suction cups wouldn't stick to anything right out of the package. I was going to return them, but tried one in the bath and after it getting wet and leaning against it for 30 minutes it did stick to the side of the tub and was the size I needed. Works well now but don't expect to stick it to your tub a leave it there, because it does fall off when it dries.
