After 20 years of using tampons, this product has literally been a revelation to me. So much less messy, and so flexible - I love the fact that I now have no need to worry about flushing away or finding a dispenser for those nasty used 'items' for a week every month. It can be left in for 8-12 hours, which I like if I'm out and about for the whole day; and reused for years, which is good if you're travelling in places that don't have regular supplies of these items. And it also makes night times a whole lot more relaxing.
It took me one or two goes to get used to using it. Since then I have found it ridiculously easy to use - identical to a tampon really. I will admit, however, that once I had cut the stem off, as instructed in the packaging, I panicked the first time I tried to take it out, until I had got the hang of using my pelvic floor muscles to move it into an 'out' position. I recommend reading the Mooncup website for advice, if you struggle the first time.
You can't feel it at all when its in place, by the way.
I thoroughly recommend that you throw away your towels and tampons and invest in one of these straight away.
I'm not a member of the green lobby - I work in the City and regard myself as very picky about appearances and brands. I just think this product is a MUCH better alternative to anything else that's out there.
Don't be nervous or put off. Go for it!
