These are my favorite cups to date. If you’re looking for a softer and/or smaller cup (which I am) they’re perfect. Firmer cups just make me feel like I have to pee all the time (and hurt when I take them out) so I’m always on the lookout for super soft choices. If you’re not used to softer cups, you will have to double check that your cup has opened all the way. They do not pop open as easily as firmer models. But it only takes me about fifteen seconds to run my finger completely around it to push on my walls and ease it open. Like any cup, you will get leaks if it is not completely open. (Unless you use the Femmycycle which doesn’t open all the way.) My cervix does NOT sit low (most of the time) so I prefer a longer stem. (When my cervix does occasionally get lower, I can't wear cups like this at all and have to switch to Instead Cups. Having a cup constantly hitting your cervix is not pleasant and will make you feel like you have cramps.) So long stems are a plus for me. Also the stem is solid not hollow, so there's no place for bacteria to hide. I would have liked the Anigan (Eva cups) cups here on Amazon if not for their short stem. (You can always cut stems to make them shorter, but I can’t magically make one longer.) Their softness is very similar. Also Anigan’s small size is like R-cup’s large (which I occasionally use my first day if my flow is heavier). If you’ve tried Lady Cup’s small size (40mm diameter) or Lunette’s small size (41mm diameter) , R-cup (40mm diameter) is a good match size wise. It's just way softer. Except for the Femmycycle, the R-cup is the softest cup I own. My only complaint is the color representation on Amazon is horrible. I knew that before purchasing though, so there were no surprises when I got them. There are accurate pictures online if you want to do a search. All the colors are very pastel and soft. They are neither completely transparent nor completely opaque. If you are concerned about these being made in China, I did a burn test on a piece of the stem. (If you put silicone in an open flame it resists burning and all you will wind up with is ash. If it’s not pure silicone, it’ll catch fire easily and turn into a sticky, melty mess.) The R-cup stem took an extremely long time to burn, and it turned into nothing but ash (after my persistent pyromania finally paid off). I have all the colors except blue. The yellow is probably my favorite. It's pretty/sunny and doesn't show discoloration as much the other colors. BTW - I'm 34, no children, and I always buy the smallest size cups. I can wear the bigger ones comfortably (as long as they're soft) but I find them slightly uncomfortable to remove. (I just can't fold them as tightly for removal as I did for insertion.)
I love my cup, the fit is great. Only problem there are 2 small holes right at the rim of the cup. I assume they are there for suction issues when removing the cup. The problem is you can't get them clean. I wash and wash my cup and it smells to high heaven.
