I have only used it once so far. It's very flexible and easy to insert. I had some trouble getting it into the correct position and had some leakage at first. I also had trouble removing it as it felt like it had moved higher up. If not for the thick stem with the bumps, I worried that I might not be able to retrieve it. I got the black cup which gives the illusion that it's less messy, as you can't see the blood. I would recommend this cup to others.
