Reviews for the product show a mix of opinions, with many even claiming that their cramps lessened after moving away from tampons.

One user who suffered from “agonising” period pain writes: “The discomfort/cramps that tampons caused was no more! Because of Flex my paranoia of my period is over! I might still have pain, but the confidence and peace of mind that Flex has given me is life changing. I plan to never use tampons again.”

A second user agreed that the product was “life-changing”, writing, “It feels weird to call this a ‘life-changing’ product, but I went from my period being incredibly annoying every month to being just another day. It’s pretty awesome.”

But many of the reviews point out that removing a disk full of blood from your vagina is still a messy business, and it sounds like something you would only want to do in the comfort of your own home, possibly in the shower.

Another reviewer writes: “It was actually easy to put inside, I didn’t feel it at all while it was in there. The claims on no leaking even while making love are true… BUT taking it out was so messy, I ended up covered [in] mensies and it was super uncomfortable.”
