Mooncup was the first menstrual cup I ever used. Mine lasted for ten years before I dropped it down the toilet (after a toilet incident where...lets just say there was no reusing the reusable cup after that) and after subsequent years of using alternative menstrual cups by a variety of companies and feeling dissatisfied, I returned to the original and (in my experience) best cup out there. When I decided to buy another cup, I was a bit nervous about getting the right size - I contacted customer service and Sophia, who answered my emails, was really helpful and informative. Stellar company with proper ethics. Will recommend Mooncups to anyone who will listen.
