Flex cups

Re

Okay y'all...

I found this new thing. It's called a flex cup. It's like a menstrual cup but it sits up right against your uterus and can be worn for 12 hours.

My question is, has anyone tried these? All Ive ever used is pads and an occasional tampon when my pads cause friction sores on the inside of my legs. So I'm pretty intimidated...
