At first it is a little scary because of the size of the thing, we wonder how we will succeed in putting it in place, but with practice it's going very well.
But I think this kind of protection is not made for everyone, as it's still quite special and a little cra-cra (especially to remove it).
By cons, for large flows, the top!
With my copper IUD, I have very heavy periods, it was unmanageable with stamps. Thanks to the lady cup, I am calm all day. I put it in the morning and retires at night in the shower. I rarely need to empty that day.
This is real freedom. In addition there is soon feels at all, it's very comfortable.
The pros: reusable, practical, large capacity, confrotable
The -: not always easy to remove, we need to stand the sight of blood when it is removed, it may seem expensive to buy but it quickly pays, need the port protege slip for small leaks daily
