I bought my UK Mooncup back in February, and am thrilled to bits with it. I love the fact I can put it in beforehand and don't have to worry about finding a loo when I feel it start. Last month I was on holiday in Italy with my Mum and I was really nervous because I'd never used it out of my home area, but it was fine. I felt my period start as I stepped onto a bus in the middle of rural Tuscany, but could be completely comfortable and confident. The fact that there is no waste means that it was *less* obvious than usual, and although I did take a handful of other supplies, I didn't think of them once!
So generally, a big WOOT for the mooncup!
