Review on 🚿 Rotating Shower Caddy - HangHover Shelf for Corner Wall in Bathroom, Convenient Adhesive Shampoo Holder Plastic Organizer - Large Size 4.3x13.3x3in, Drill-Free & Damage-Free Mount, 2.7kg Weight Capacity - White/Grey by Brooke Daniels

This thing is just amazing in its holding power. Much better than the normal 3m sticky wall hook. You might be unlucky with tiles, but I have plastic sheet shower screens. And it works great. The only odd thing is that when tilted and overloaded, it sticks out but doesn't fall. Great article if that's what you're looking for. Update: I wanted to add here that if you accidentally bump into it in the shower, the product probably won't stick to the wall. This might be a problem lol because it happened to me. I will ask for another sticker and hopefully they can send one.
