Ventouse pour panier de douche, tablettes de douche amovibles pour la douche intérieure, organisateurs de salle de bain sans perçage et support de rangement pour l'aspirateur à shampooing

I was thrilled to get these for my shower. I followed the directions as written. Only one of caddies remains in place after approximately 3 weeks. How do I get an alternative or replacement suction devices?

Perfect size and easy to install. Should be simple to move if needed.

Just what I wanted, very nice size and it holds all of our products! Great price. Thank you Wayfair!
