Ok I know there have been a million mooncup threads, but this is an emergency. I really need some convincing that this mooncup thing actually works. So far, I have spent the best part of the day trying to retrieve the damn thing from what I know realise is a vacuum powered undercarriage. It reaches a certain point and then is sucked in, never to be seen again. And it leaks. I'm also not overly keen at sticking my hands up there to find it. And my bathroom now looks like a scene from psycho. So please someone convince me that they actually work
