Well I tried it for an entire cycle and it actually worked with no leaking. I find the C fold or punch down fold works best for me. Then I push on the body of the cup a little so it will sort of open, even though the cup doesn't need to pop open to work. This seems to do the trick for me, but if it doesn't work for you just try different folds until you find one that does. I love this cup now and will be using it regularly mixed with a few of my other cups, because I just can't decide on a favorite. There are times that I feel my cervix is too low for this cup, so I will be using another when this one doesn't work. I'm thinking about saving up for the small/teen version as well. My only complaint is the reaching in to pop the rim out to dump. I like that it's a no spill design, but the rim can get dirty. So make sure you are prepared and cover it a little as I've heard if your flow is heavy it can make a mess once it pops open.
