    I’ll never use anything else!

    This literally changed my life! It makes being on my period and continuing my regular activities as easy as possible, sometimes I even forget I’m on my period. Completely solves the issue of peeing with a tampon in (ifykyk), I’ve even used it camping before with no issues! Seriously I’ve convinced all of my girlfriends to switch and now they can’t go back either!! Make the switch! Plus the cleanser, wipes, and instructions make this the best transition ever!

    New go to!

    Super easy to insert and I don't feel a thing throughout the day. No dry rubbing or wet feeling. I struggled to get it out the first time and had to have my boyfriend help me but I got the hang of it around the third time! Also, possibly the best thing, NO LEAKING! I was a little worried as I have a tilted cervix and have had two kids but I had no issues!

    Life changing

    This has been life changing. I actually forgot that I was on my period for a few hours at a time. No wet diaper feeling. You don’t feel anything. As someone who has very, very heavy periods (yes I need to try harder to get it addressed but anywho) this has been a God send. I don’t need to to to the bathroom every hour and spend a lot of money on pads and tampons! Thank you for designing this. Finally not mad once a month about being a woman. I feel like a modern woman with this! Also I found it easier if anything than a tampon. I thought it would be tricky or awkward at first but I read the instructions and got it right away. Thank you modern science and flex team!

    I was against period cups at first

    But then.. I tried this! I’m telling you I will not go back. No leaks, less cramps, and you cannot tell you are wearing it.. so much more comfortable than items for period care.
