The Softdisc Menstrual Discs ($11) are actually not menstrual cups. As the brand name implies, they are menstrual discs that are meant to be placed at the base of the cervix. Because of their shape and intended placement, the brand says they can actually be worn during sex while menstruating. However, these discs aren't reusable; each box comes with 14 single-use discs that are made of a FDA-cleared medical-grade polymer that's free of latex, silicone, phthalates, and BPA. Given their disposable nature, they might be a good option to use when travelling or for those that don't like changing their menstrual cups in public settings.
As for shopper opinions? Overall, the product has nearly 7,000 five-star ratings on Amazon, and many reviewers note they prefer these discs to tampons and even reusable menstrual cups.
