It really does! No leaks or weird issues. With a little practice I'm now able to get it in, opened, and suction within a few seconds. It's better than my Diva, in fact it blows it away. Sometimes I'd have to reinsert the Diva (and my Mooncup Uk) to get it to suction--not so with Lady cup. It suctions perfectly every single time. It also sits higher inside my body than the Diva did, which makes it even more comfortable. The gigantic holes are so easy to clean too. So soft, so comfortable, I'm in love love love!
