I've never heard of the Mooncup, but I use something called the Diva cup, which sounds like it's pretty much the same thing. I've been using the Diva up for years, and it's been awesome. Although, last year I was in India, and I was on my period, and I had to empty the cup, but the only place to go was a trough that you shared with a bunch of ladies. So I emptied the cup, and the lady next to me looked like she was going to have a heart attack. lol. I had to show her the cup and try to explain with my very limited Tamil, that I had not just murdered someone.
