Works great!
I've used Diva cups in the past, and this works just as well if not better. I got Size B because I've given birth vaginally, and it fits easily.
Most folks can use either size, but here are some reasons why you might choose one size over the other:
Size A | Size B |
Choose size A if you're new to cups or have trouble inserting tampons. | Choose size B if you've given birth or have a weak pelvic floor. |
