These actual work well. I had no problems with leaking. They did not irritate my sensitive skin. I wear them when I didn't have the baby with me and if I'm only going to be nursing a couple times while out. They are stuck to your skin and I didn't want to be sitting out in public trying to readjust them. :)
Only worn once so far, but they stayed on and worked as advertised. I like that they give me the option to go braless for formal events or when wearing shelf-bra camis---something I couldn't do before for fear of leaking.
