Review on AmazerBath Corner Shower Caddy With Hooks, Adhesive Shower Shelf For Bathroom Storage, Stainless Steel Shower Organizer Wall Mounted, No Drilling, 2 Pack, Nickel by Gerard Hudson

Shelves seem to adhere to the wall really well. These are not suction cups. They are very firm adhesive strips. I did have to be careful on my placement as my walls are not completely straight. Still fit just right. Definitely cleaned up the look of my shower as opposed to a freestanding shelf. I have a soapdish with this type of adhesion and it has done really well for the past month. No air bubbles showing up. I was able to put the shelves in a corner that is not highly visible from the outside of my shower. Also out of the way.I would not put some thing on the shelves that you will be pump dispensing while on the shelves. You could put too much weight from pressure against it.
