Thanks for the response britjojo - I wasn't aware that there were variations of the mooncup idea made by other companies.
Elaine - you can find out more about the mooncup on their company site (
http://www.mooncup.co.uk/index.html).
I don't have heavy / painful periods, but I am concerned about using tampons for health reasons (sticking bleached material somewhere so sensitive can't be healthy, let alone the risk of TSS).
Based on what you've said, Britjojo, I think I'll give one a shot in the near future.
