A well-known menstrual cup option, the DivaCup Menstrual Cup Model 1 ($33) has scored 9,187 global ratings — 76 percent of which are five stars. Model 1 is meant for users between the ages of 19 and 30, or those with a medium flow, and is made out of medical-grade silicone. Based on reviews for Model 1, a slight "learning curve" is there in terms of insertion and removal, and leaking isn't a major issue. Some that did report leaking in their positive five-star reviews, however, mention it could have been due to an insertion error or that they might have needed a larger cup for their flow. The brand also offers two other menstrual cup sizes: one for a lighter flow and another for a heavier flow.
