I have NO past exposure with these menstrual cup things. I wanted to try one so I am glad I got the opportunity with this product. I am taking stars off without being able to fully test it out mainly because of the 'storage bag' it comes with. They tell you to store it in the bag between uses, but all the bag is, is a plastic resealable bag that I see falling apart after a few uses. I would make it out of some kind of cloth that can be washed or a waterproof material.
