I highly recommend this brand for anyone with a finicky bladder and a somewhat high cervix.” (Amazon.com)

“Amazing product!!!! I’m so over convention methods definitely sticking with this! Very comfortable! I thought there would be a scent but thankfully none… I have told all my friends and they are on board.” (Amazon.com)

“This cup is really soft, more than I expected. The color is less intense than the photos but still a pretty light blue. It has a nice stem (circular and not hollow) And it’s grip rings are nice. Shipping was decently quick as well!” (Amazon.com)

    This cup is too soft for me. I find that as its very bendy it creates a suction on the side inside and doesn’t stay open even if it try to twist it inside and poke my fingers around ( not so comfortable as you can imagine ) . Because of this it makes me leak . I’m going back to a Moon cup which is less bouncy .

    It really is an incredibly soft cup which was perfect for when you start your regular cycle back up after finishing postpartum. I’d say if you can’t pass the sneezing without peeing test try this cup, other wise your muscles will crush it and it won’t open up. Altogether a really good inexpensive cup for those who have a relaxed pelvic floor.
