iDesign Power Lock Bathroom Shower Plastic Suction Cup Hooks - 2 Pack Clear - Strong Adhesive Hooks for Loofah, Towels, Sponges, Robes - Perfect for Shower Organization & Bathroom Storage

These are great! As with anything suction, they will fall off at some point and have to be re set. However, they stay stuck for months at a time. I have used the same ones for 5 years. They don't look as good as they did new due to our hard water so I decided to get a new set.First of all I agree with the other reviewer who said that everyone complaining about the cup not staying on the wall probably didn't put it on right. It definitely sticks to the wall pretty tightly once you create the vacuum by flipping down the hook and I'm using it on a tile wall with some paint drips that I didn't specifically clean.That said, the problem I have with it is that I use it for my hand towel at chest height. Whenever I use the towel I pull it towards me which pulls the hook towards me as well and makes it flip up. So far it hasn't led to the whole thing falling down yet but I do have to either be super careful about not pulling the towel too much or push the hook down again every time I use the towel which is a bit annoying.So I'd say if you're going to use it to hang something that won't move often or you will be pulling upwards or downwards, this is a great choice. If you'll be pulling something off it vertically, maybe pick a different product.These suction hooks hold my Loofah very good. It dose not fall of the wall at all.Our shower has textured natural stone tile rather than smooth ceramic tile. These suction cup hooks do a pretty good job of holding, even to this less than ideal surface. They will fall off after a few weeks, but given the surface, I think that's more than acceptable.This little suction cup is easy to put on and easy to take off. It holds very strong to smooth surfaces due to the locking suction design. However it has a tendency to not hold anymore once the suction cup area becomes dry. Then your things are on the floorIt sticks well to a porcelain shower wall. Very convenient way to hang a net scrubbie. I would recommend.These hooks are great! I was reluctant to buy them at first because the previous reviews were so mixed. Some said they worked and some said they didn’t. But I took a chance since the price was great, and I am really glad I did! Like the previous reviews said, all you need to do is read the instructions. You can’t just stick it on the wall and hope it stays. There is a specific way to put it on the wall and lock it into place. The hooks haven’t moved at all since I hung them up. And I even waited to do this review because I wanted to give it time to make sure they stayed in place for several days. Plus I take the items on and off the hooks during each shower and the hooks still don’t budge. So they can definitely be used to hang items that you use daily. Also just as an FYI, I tried them on tile and glass and both worked. I ended up putting it on the tile. But just so you know that either option would work. I highly recommend these hooks, especially for the price! As long as you install them correctly, they will absolutely stay in place!The suction works great for holding my shower puff. I followed the instructions and placed it on my shower wall tile with no problems.
