These are very easy to install and they look good, too. As one might guess, the suction isn't all that strong. It depends on just how hard you can push on the suction, for how long it will stay up. The one that fell down within a week, I had my husband push on the suction when we put it back up. It seems stronger now.
We're only using them for towels and swimsuits, nothing heavy. We will be taking them with us on vacation also because we can take them down afterwards. So the removability part is important for us.
