I was really excited about these, until I tried to use them. They are really tricky to put on. I'm sure once you get the hang of them they are great, but I wasted all of them trying to get them to work. I'm a C cup and nothing I did seemed to make them want to hold anything up. It didn't help that the directions suck. I was really disappointed. They probably work fine for a smaller cup size but I would not recommend them for larger sizes.
