[THE PROS] Good for high cervix and heavy flow - Cup doesnt get too high to reach when removing. The material is also smoother and softer to fold which makes it really comfortable and easy to insert. Been a cup user (of various brands) for a while and I truly swear by it - good for those who usually have chunks and clots during period. I wore them for 4 -6 hours on heavy days and 6 - 12 hours on lighter days which makes it perfect for vacations and outdoor activities.
[THE CONS] Since the lily cup has a flat rim, comparing to the generic rounded rims of menstrual cup available, this design makes the suction really really tight. Breaking the suction is harder (you may need to slip in finger higher and press harder to break suction), which I won't recommend for beginners.
