I have only used it during one period so far and I'm sold! Don't need to think about it, so nice to go and do what one wants and to not constantly have to think about if you have tampons with you etc... I love my cup!
I think you are awesome. Both with your product that changes life, mine included, but also everything you do to spread information and knowledge.
A small revolution is what the menstrual cup is. No purchases, no smell. Freedom to just be for a whole day, no waste, always available, no chafing, no itching. Simply the best!
