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.
Happy 3rd anniversary! Best invention ever - freedom in a little cup!
