I’m in love with these
These genuinely make me feel like I’m not on my period. It maybe took me 2-3 cycles to get the hang of using them, but now that I’ve perfected it I will never go back to anything else. I always would leak in tampons despite never filling them up, I tried a cup but I couldn’t figure out how to get it in, and pads are just gross. But these literally fold smaller than a finger and all I have to do is push it in. They literally stay in for 12 hours and I have no leaks, no cramps, and allow me to go about my day like I’m not even on my period. These have changed my life and I recommend every menstruater tries them!!

Game Changer
This product seriously changed my life! I used to have DEBILITATING cramps on my period.. maybe not every cycle but every other cycle I would spend at least one day, if not two or three days barely able to get out of bed. I would have cramps so bad that I almost passed out one time! The type of pain where you are literally closing your eyes and squeezing your fist to bare the pain... I tried taking Ibuprofen, drinking ginger tea, I even started taking birth control to try to help the cramps, and nothing helped. And then, I tried the Flex menstrual disc and just like *that*, my cramps just about disappeared! I don't really understand how, but I am so grateful! Now I can pretty much carry on like normal during my period. The pain is just a whisper in the background of my life, no longer shouting in my face! TYSM FLEX !!!! <333333

Changed my life
I will never look at a box of tampons the same. These flex discs have changed my life. I don’t know why or what the science is behind it, but after I insert it, my cramps are relieved unlike a tampon when the chemicals are releasing in our body, I cramp so much worse. I’m giving praise to whoever invented this because thank you from a woman who has excruciating pain painful periods to now finally getting some relief.

The Best!
I seriously love this product so much, I recommend it to everyone! It is so nice not to worry about leaks during long hours at work. I went on a long hiking trip this past summer and this disc made it such a breeze. Keep up the good work!
