Anyone ever use a menstrual cup?

I just only just found out about them and I'm liberal of curious to try one.Seems like it would be a huge money depositor in the long run.I've hear that some people enjoy a hard time near them but with practice they gain better at it.
Anyway so if you could please tell me more or less your experience with them,what variety you use,and would you recommend them.Thanks. Well I tried a disposable kind from Rite Aid (drugstore) and I bought them the dark before i needed them. On the box it said you could wear them overnight (up to 12 hours), so I thought a obedient time to try them would actually be the dark before. So I did, and it worked faultlessly. So I thought it was a move about for the beach! Wrong! Turns out those things really do stipulation a lot of practice to achieve it right. I never knew what I did wrong and i haven't have a need to try them again since. They're still sitting below my sink.
