Clearly a sturdy cup. Switching to a cup just takes practice and confidence, be prepared to spend your first cycle learning about your anatomy! Learning to insert the cup felt straight forward enough, no leakages either. However, cup removal takes practice and privacy, I wouldn’t plan on using this outside of the privacy and comfort of home for the first cycle or two, just to get used to it. I won’t be looking back however! I’m so glad I have made the switch.
