I think lily cup one is the most comfortable because of the material and the collapsible design with the case. And i started to think why Intimina doesnt create the lily cup one for size B? Because many friends of mine want one but they worry to use this because they already have a vaginal birth. :)
I bought mine a month ago so I've only use it for one period cycle, it's very useful and it's going to save me a lot of money, it's foldable and has a small container which is useful to leave in my bag. The only thing I find is it keeps leaking. Maybe I need to reassess how I insert the cup, but I have to wear a pad with it so I don't make a mess.
I'm new to the cup world and really took time to weigh pros/cons, convenience, storage, etc. This cup is perfect! I love that it is collapsible into a small discreet case, easy cleaning, and the loop pulley is great!
