Just wanted to post this having read various threads on this subject in the past - lol in amazement when reading the latest Boots magazine to see an advertisement for a MOONCUP 
(sorry if this is now everywhere - I don't get much time to read mags these days with the kids).
Anyway, exclaimed Ohmigod outloud - resulting in then having to field my 6 year old's "What...what it is mum, let me see..........."
Actually I'm seriously considering getting one!
