i have had them up for a few months now. they have remained. i thought with all the moisture they might unstick and fall off. THEY HAVE NOT. So you put them on one side of your shower curtain. i would say the one furtherest from the shower head. you can put them on the other side too, you would just have to thread your shower curtain in the clips every time you get in and out. but i don't have anything on the shower head side since i don't direct the nozzle that way, only toward the back of the shower. so i have them on the side furtherest from the shower head. I have not had a drop of water escape. If the curtain pulls out just rethread it. takes about 2 seconds. if you have water on the floor this is all you need. PROMISE. from a real person in temple tx. ps. make sure where you want to put them before you stick them on. I have one about 4 inches from the bottom and another one midway. there are 2 in the package.UPDATE: i thought i had posted this already. guess not...well i have had these for a while. the same initial set has not come apart from the shower and they are so easy and effective. best fiver i ever spent. not a drop of water on the floor!!!
