I have had this exact menstrual cup for about 6 years now, and she is still going strong! I will never go back! I have had PCOS for over 10 years and after using tampons and pads for years and dealing with excruciating cramping and pain during periods I knew it was time for a change. Every since switching years ago I am beyond thankful for this product as it has helped ease my symptoms during my period! If you aren't sure about switching this is your sign to give it a try! Thank you so much!

I was very hesitant and was even thrown off on how in the heck i was to have that even be used. Ended up figuring it out and wow its now the best thing ive bought! Tampons always gave me the biggest cramps plus very uncomfortable. Pads just tend to feel it all and also just not so discreet. The cup has made my life so much easier. No constant changing pads/tampons is amazing!!!!!

I bought this cup a year ago and felt the need to come leave a review because I truly don't know what I would do without it. There was a learning curve at first but after a few months I mastered it and can go all day leak free. No smell, no running out of tampons, no dealing with your period all day - I just have to change it once in the morning and once at night and I'm good to go! The tab makes removal easy and I can't feel it at all if it's in correctly. Stick with the learning curve and once you master it you will thank yourself!

I’ve tried a few different cups and this one takes the cake. It’s the easiest to use and very comfortable.

I absolutely love the flex cup at first it took me a little while to learn and get a good technique but after that, absolutely amazing I had no leaks no problems I could barely feel it which was something I was worried about at first but it honestly feels like a normal tampon and for somebody who is very allergic to bleach tampons have always been a struggle for me but since I started using the flux cup I haven't had any issues regarding my health at all which I've been so unbelievably thankful.

It's easy to pull out because of the ring shape pull tab! I was scared to buy a period cup because I was scared of it being stuck inside of me because of my dexterity issues due to my multiple disabilities, but this works amazingly and I don't have to worry about it at all!!! It is a bit hard to put in the first time, but it definitely gets easier as you practice and I have almost no issues after using it a few times.

Seriously. This cup is the best. It’s my favorite of all the different ones I’ve tried. Soft texture, doesn’t visibly stain, easy to insert and remove. Comfortable. Easy to clean. I use the foaming cup wash and it is also amazing and not irritating at all. I’m a for-life-customer and tell all my friends that this is literally life changing.

I recently got a Flex Cup after learning more about the harms that tampons can cause to your body. I got it at Walmart for $30 and it was definitely worth it. I’ve only used it for a few days but it was very easy to learn how to use properly, and I have not had one single leak. I don’t feel it at ALL! Would 100% recommend, even if you are nervous. I was, and it was so worth it!

My first cup and I love it although it’s not 12 hours for me because I bleed heavy I still love it minimal to no cramps and no itching from toxins of pads and tampons if you’re thinking about it do it!!!

I purchased this to assist me on a long flight plus concert night. I have heavy cycles the first two days of starting and I knew that I'd have to empty the cup at least twice before my final destination. The emptying process can be much, carry wipes. The cup saved my life and embarrassment. My travel was comfortable and it brought me confidence during the days of madness...tnx!!

First time using the cup, I immediately felt when it suctioned. Super easy insertion using the tulip fold! I did use a couple different discs before trying the cup, I love the discs but wanted something that I didn’t need a pantyliner with because the disc auto dumps and after a little will still come out after dumping. Both are extremely user friendly and the pull tab on the cup is life changing. The key is being relaxed and relaxing your pelvic muscles for insertion. No leaks, no discomfort, easy insertion! No toxic materials, lasts for years, good for the environment?! Best investment I’ve made for my menstrual health.

i’m gonna start off by saying i love the reusable disc SO much. i’ve tried other cups and it’s always so uncomfortable/hurts, taking it out is anxiety inducing, the suction aspect is just a nightmare imo. the disc is so comfortable you literally can’t feel it once its placed AT ALL, it’s easy to insert and place once you read the instructions. its good for the environment! it’s comfortable! it’s reusable! and the best f$*#!? part is that it EMPTIES ITSELF every time you pee. it doesn’t get better than that. now that’s also the only down side to the disc, im an active girly and have to move my body in funky ways sometimes, so if you are using this and moving/squatting with this in, don’t (: just like the instructions say that disc, that little dam that holds back unmedicated aunt flow at the family reunion, folds and pours right into your pants unmercifully. that being said i have yet to try any ✨spicy 🌶️ activities with it yet but i imagine the self emptying bit might effect that as well in certain positions. just heed my one warning and then have the most enjoyable period you’ve ever experienced. from someone who fing hates bleeding<3

It took a hand full of tries for me to get it to stay in place and make sure it was open but with a couple tips I read online it was easy to figure out. This was my first menstrual cup so I was unsure of how it worked and if I'd be comfortable enough with my body to use it. I have to be a little more involved with my lady bits using the menstrual cup but I found myself feeling more comfortable and proud of my body the more I became familiar with it. The cup is unnoticeable when inserted properly. On the first heavy flow, I empty the cup 1x during the day and the rest of the week I empty it in the morning and it stays in until I go to bed, unless I'm in the shower because it's super easy to clean it in the shower. It's also nice to have the convenience of taking it in and out as frequently as I want cuz it does not hurt to take out when it's empty like a dry tampon. It's also nice for the end of the period days when the brown gunk is still lurking for a few days. I know it's gross but it's real life so just letting you know it's great for those days too. I would suggest the company adding these two tips to the packaging. 1. When inserting the cup push the muscles like you're pooping, when the cup is fully inserted relax the muscles. This will create a suction to hold the cup in place. When I do this I can feel like cup be pulled up slightly by the suction and it never slides out. If I don't do this, it does slide out. 2. To make sure the cup is fully opened turn it or twist it around in a circle, not that it will need to make a film circle but doing this motion will help you feel it is open and then you can continue insering it with confidence it will not leak. This tip should probably be first since it's done first when inserting the cup😁. But it's not always as necessary as the first tip. I hope this helps all the ladies using the cup and I hope it helps prospective costumers feel confident purchasing and using the flex cup! I just remembered the most amazing part of this menstrual cup is obviously the pull tab! It's the reason I will only ever use this kind of menstrual cup! Ok that's all now.

This cup is a *chef's kiss*! Using it since 2020... and Im still ising it even after I have birth. Still fits and all. Although the pull tab broke, I could still use it. Maximazing it until its 5th year.

This is the second time buying this cup, after about maybe three YEARS (maybe a little more) using it, it got a bad smell that I couldn’t get rid of so I guess it was the end of its life time so I discarded. I still LOVE IT!!! No more spending money on tampons or pads (which I hated using) no more waste and it holds more than a pad or tampon, I can spend the whole day with it and not accidents! Is my best investment. Before this one I bought two different brands but they had the same issue, hard to get it out, but with the flex cup design is so easy without the possibility of any spill out of the cup

Gone is the discomfort of tampons and pads! Leaks are almost a thing of the past, too. I keep two so it's easier to change one, then clean the other and let it dry before it gets used again. My only complaint is that when my original cup gave up the ghost, it did so by the pull tab breaking while I was trying to remove it. I had to figure out how to get it out without the pull tab, which was a bit harrowing! Still, the lasted for several years, and I've already ordered a replacement.

Frequently Asked Questions
How do I clean my silicone menstrual cup or disc with Flex Foaming Cleanser?
Rinse your silicone period cup or disc with cold water. If you’re using Flex Cup, unthread the pull-tab first. With a generous pump of Flex Foaming Cleanser and some warm water, thoroughly clean the entire cup or disc (if using Flex Cup, give some extra love to the air holes at the top). Rinse well with warm water and allow the cup or disc to dry before reinserting.
Make sure to remove, empty, and clean your reusable menstrual cup or disc at least once every 12 hours.  Flex Foaming Cleanser is designed to be used on all silicone period products.

What's the difference between Flex Cup and other menstrual cups?
We know you've probably been searching the internet for days to find the perfect menstrual cup and you're probably thinking, what's the difference? They're all pretty much the same, right? Not this cup!
Flex Cup can be safely worn for up to 12 hours. It's hypoallergenic and made with medical-grade silicone—but what makes it truly stand out is its super-soft, adjustable pull-tab. The pull-tab threads through a small hole at the base of the cup and attaches to the inner rim (at the top). When you pull down on the pull-tab, it collapses the side of the cup inwards, breaking the suction seal for you.
Wait, don’t other cups have a stem or “pull-tab,” too? Sure—but those stems are nothing more than a guide to help you find the base of your cup. If you tried to pull down on a traditional cup’s stem without first breaking the seal, you could put your vagina and cervix at risk for suction-related injury or discomfort.
Imagine trying to get a suction cup off your shower wall by pulling straight back: probably not gonna work, right? You have to get up under that suction cup by peeling one side away from the wall. Same idea with a menstrual cup! Typically, you have to manually grip the base of your cup with a finger and thumb in order to break the seal before you pull it out.
With Flex Cup, you can skip that step and use the pull-tab the same way you’d use a tampon string. This design makes Flex Cup beginner-friendly, more accessible for those with disabilities, and perfect for IUD users.
