LOVE this shower caddy. This is actually our second because we liked the first so well. The screw at the top with a non slip rubber inside keeps it from sliding down the pipe that comes out of the wall and the suction cups at the bottom keep it stabilized on the wall. Plus it's a nice bonus that the shelves move up and down depending on the size of your bottles. It holds enough, not tons of products but enough, 4-5 per shelf depending on size of the bottles.
