i would always use tampons. never pads, they gave me rashes. but after a while of being completely annoyed by the process, $ (of both buying them and toilet paper to wrap them in to dispose of), and just the general health issues - this was crazy. i called my sister and told her she had to buy one, i think cups should be way more popular than they are!!! especially this one, my boyfriend bought me the wrong size (2 instead of 1) at walmart, and they reimbursed me with a size 1 free of charge! absolutely amazing company. i love flex so much !!!!!! ugh!!!!!

I have made the switch! Haven't used a pad or a tampon since! Absolutely comfortable AND was a change in my life. I can't believe how much time,money, sheets and underwear I have saved! THANK YOU FLEX CUP!

Literally writing this on day one. UK reviewer and the delivery of this happened to arrive on the first day of my period so I got to try it the following day after a thorough clean! I’ve tried mooncup which is quite rigid (& possibly too big for me) but what appealed for me here was the pull tab (because I kept pinching the inside of my vagina trying to find the stem on the other one). It was such a relief to wear today, I had a teeny bit of leaking (nothing that a panty liner can’t manage if I’m not wearing period pants) and I think I’m still getting used to the fit but the removal! Oh my goodness, it was what I had hoped. The stem is comfortable to wear and easy to remove. I even managed to insert it whilst my 3 year old was nattering away to me. It was slightly tricker to insert because of the inside stem so was harder to have in place but I’m confident I’ll get used to it. I have had some difficult gynae issues so not the best at doing anything internal. I now have confidence using this cup (probably still only on my heavier days) and am not dreading going on holiday now!

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!

This was a game changer! I work in a field where bathroom breaks are far in between and this decreased stress with this lasting me between 10-12 hours depending on my flow that day. It did take a few hiccups with my first time using it during my monthly period but now I feel confident.

My first time with a cup & it some trial and error. I thought it just might not work for me at first.. but the key was inserting it more parallel than perpendicular to the ground. Way more comfortable, lasts much longer without leaking, more affordable & sustainable than a tampon. Don't give up!

I wanted to love this so badly. I’ve been using menstrual cups for about 8 or 9 years now, and have never had such issues with leaking until using this cup. I make sure it suctions/seals properly, it feels fine and comfortable but.. within an hour of wearing it out of the house for the first time it began leaking so badly I had to run to the bathroom during a work meeting to take care of it. This cup is terrible. At home I didn’t notice it as badly because I wasn’t up and walking about as much, but once I started walking to work from a parking garage I could feel it start gushing out. After a full day of wearing this I just can’t. I’m so embarrassed and will be trying a different brand. I wish I could get a refund.

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.

I really love the flex cup. I've tried to use cups before but found them very difficult to remove so was really happy to find one with a pull tab. I have given it 4 stars rather than 5 as my cup has started to become difficult to remove - the tab comes further through than it should and then gets stuck the wrong side of the cup. It is fixable but very annoying. I can't find anywhere to ask how to stop this from happening - if I don't keep pulling then it won't come out at all!

I was looking forward to trying out the cup because it removes like a tampon and seems like less mess. I have used the disc for a few months. The disc is easy to put in, can't feel a thing once inserted, but it's gross to take out. The cup on the other hand was extremely painful to insert. I ordered the size 1 and knew it wouldn't fit just by looking. I tried all kinds of folds and positions and eventually gave up. Back to the disc it is.

I’ve use my flex every period for four years and am only now coming back to buy a replacement. This cup is a dream!! So easy to get in and out, can go a whole day without changing it. Worth every cent.

Lasted about 2 years before the pull tab broke and the seal stopped being tight, but that's still a pretty good time. The tab sticking out can be uncomfortable if you end up dry during your period, but that's the case with all menstrual cups I think. Good enough to buy again, so good enough for 5 stars!

I love this product, I wish I had this option in my younger days, I wouldn't have missed so many water activities and sports that I love. I have recommended my whole family to use or try flex products and they love them too 😁

I like that I’m not wasting as much for products but I still have to wear other means when using the cup because I get leakage around it every single time. That’s frustrating as I was hoping I would be able to utilize just this product and not have to rely on other things as well

First month was interesting at times, but second was so much better! Being able to work on things outside and not worry about stopping every hour has been amazing! I know it will be even better next cycle.

I work 12 hour night shifts in a clean room, so when that time of the month comes along those days are uncomfortable, especially since I only take one break. I only wore pads up until now so it was definitely intimidating shoving a wide cup up there, despite being the smaller size. The punch-down fold method is definitely the easiest way to insert. The difference this made is amazing! You can definitely still feel it the first few days of using, especially if the pull string moves perpendicular to your folds or is too low. But not having to deal with that dirty diaper feeling anymore is a game changer. I no longer feel dirty and sick down there after wearing pads for a while. It’s nice to just be dry all the time. Haven’t experienced any leaks, either. I do have to use a mirror and sit on the edge of my bathtub when inserting and removing. I’ve been so afraid of down there my whole life I’ve never looked at myself before, let alone stick my hands down there. But this cup has given me a little more self confidence. Still gross, but makes my life more comfortable.

I have used other menstrual cups, which were traumatizing to try take out. It would take me upwards of 20 minutes with breathing exercises to take it out, often leaving me lightheaded and having to lie down. I cannot believe how easy Flex is to use. I honestly can’t believe it takes less 15 seconds to remove, without any discomfort.

I cannot say enough positive things about this product. I was an avid tampon user and hated using pads. I wanted a product that was reusable and could stay in longer. I saw that the Flex cup sits in the same part of the vagina as a tampon. It definitely took a few tries to insert for the first time and is messy to remove. This is my go to period product! I tell all my friends and coworkers to try it too! I tried the disc but was scared with how far it goes up. I am perfectly content with the Flex cup and will continue to use this. I 100% recommend this to anyone who is ready to move on from tampons and wear for 12 hours!

Neither of the flex cups are the right size for me. I tried size 2 first since I have given birth twice. The suction and width was right, it was just too long and stuck out the bottom. With the flexfit guarentee they sent me size 1 to try for free but that one didn't work either. It was the right height but too skinny and it fell out as I walked around at work. Thank goodness I had a back up pad on! Hopefully in the future Flex Cup will come in more sizes since I really liked the pull tab design. I need a shorter size 2. I only used each cup one time so I also wish they had a recycling program so I didn't have to throw both cups (and my money) away.

3 ways to insert Flex Cup
There are many ways to insert Flex Cup. Here are three of the most common insertion techniques you can take for a spin.
Frequently Asked Questions
How long will Flex Cup last?
With proper care, Flex Cup can last for years—so it’s better for your wallet and the planet. Most long-term cup users choose to replace their cup every two to three years, but it all depends on how well you clean and maintain your cup. Refer to our Flex Cup Cleaning Instructions to learn how to care for your silicone period cup and extend its lifespan.
If your cup is showing any signs of deterioration, such as powder or film on the cup, severe discoloration, persistent odor, etc.—that means it is time to replace.
As a reminder, do not use Flex Cup if you have a yeast or bacterial infection. Resume use only once the infection has completely cleared. If Flex Cup was inserted during a yeast or bacterial infection, remove it immediately and dispose of it in the trash.

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.

Will Flex Cup work for a heavy period?
Many of our customers with heavy periods swear by Flex products. Flex Cup is a great option for users with heavy flows. Size 01 holds the equivalent of 2 super tampons, while Size 02 holds 3 super tampons-worth of period blood. Plus, the cup's adjustable pull-tab makes it easy to remove, empty mid-wear, and reinsert on the heaviest of days.

Which size Flex Cup is right for me?
If you’re a first-time cup user, we recommend starting with the Flex Cup Size 01. If you’re a seasoned period cup pro, or if you’ve given birth vaginally 2+ times, we recommend Flex Cup Size 02. For most people, either size will work. It really comes down to choosing the best fit for your comfort.
Here’s a breakdown of each cup’s dimensions:

“but i have a heavy flow” I know it’s hard to believe that just 1 period cup could cover you for up to 12 hours, but it’s true. Our Flex Cup (size 02) is the equivalent of 3 super tampons. Period cups (and discs) are actually one of the top recommended products to use if you have heavy periods. If you’ve heard suction horror stories, we bet you haven’t heard one about Flex Cup! And that’s because we have a patented pull-tab that breaks the seal for you. Our pull-tab allows you to remove your period cup like a tampon, making removal easy and even familiar. #periodcup #menstrualcup #heavyflow #tampons

Yep, it’s a thing. Flex Cup is a 100% reusable, non-toxic period cup made with medical-grade silicone (aka not cotton that traps odors). Here are some tips to clean your menstrual cup! Every 12 hours, rinse with warm water + a mild soap like Flex Foaming Cleanser. Don’t forget to de-thread and re-thread the pull-tab of your Flex Cup (takes seconds, worth it). Sanitize once a month (after your cycle): 1. Empty + rinse 2. De-thread the pull-tab (only Flex Cup has it! Keep reading to find out why.) 3. Place in a pot of boiling water for 10 minutes (don’t let it touch the pot sides/bottom) 4. Cool, re-thread, stash in a pouch (our cups come with a cute one!) #periodcup #menstrualcup #femininehygiene #periodtalk #flexcup

Period disc vs. period cup! Have you tried both? Cups use suction to stay secure, Flex Cup however has a patented pull-tab that breaks the seal for you. Flex discs sit slightly higher than a menstrual cup, and don’t need any suction to stay secure. Both Flex discs and cups provide 12-hour leak protection. One is not better than the other, it’s just about your preference and what feels most comfortable! #periodtok #perioddisc #onmyperiod #menstrualcup

Hold up! 🧐 What does it mean “The Flex Cup breaks the seal for you??” ⁠ Allow us to explain ✨ When you gently pull on the pull-tab, the cup folds on itself allowing for it to be easily removed without creating suction. Essentially, you are able to remove Flex Cup like a tampon. This is one of the reasons why Flex Cup is not like the rest of the period cups you might have tried. We know suction can be scary 😳 and that’s why we designed our cup to be beginner-friendly. We don’t want anything stopping you from being able to enjoy non-toxic, body-safe period care! Plus, it’s pretty cool you can wear our cup for up to 12 hours without having to worry about leaks. #menstrualcup #periodtips #period

Which period product is better? Tampons: Chances are you’re most familiar with this product. Many find tampons to be uncomfortable, especially when your period flow is light. They also need to be changed out frequently. Not to mention some contain PFAS and other harmful chemicals. BUT, you have a ton of options to choose from! Period Discs: Menstrual discs are great for heavy periods. 1 Flex Reusable Disc has 12-hr wear and is the equivalent of 6+ super tampons. Period discs can be more comfortable because they sit higher (where there are less nerve endings) than a tampon. BUT, since this was most likely not the period product you were first introduced to, there can be a learning curve. Period Cups: Menstrual cups are also great for heavy flows. Flex Cup also has 12-hr wear with Flex Cup (size 01 ) being the equivalent of 2 super tampons and Flex Cup (size 02 ) the equivalent of 3 super tampons. People are usually more familiar with period cups than discs, BUT are sometimes nervous about the suction. That’s why we invented a pull-tab that breaks the seal for you! So you can now enjoy the leak protection suction provides, while also removing our cup essentially like a tampon. #menstrualdisc #menstrualcup #heavyflow #tampons

Who feels like they lose a gallon of blood every period?? Turns out the average amount of blood lost per day on our periods is around 12mL. BUT for those of us in the heavy flow club, we got a tip! Try a menstrual cup. Flex Cup comes in 2 sizes. Size 1 has the capacity of 22mL (2 super tampons) and size 2 has the capacity of 30mL (3 super tampons). And before you write off a period cup because of suction, we already gotchu! Our cup has a patented pull-tab that breaks the suction for you!! It basically removes like a tampon, but unlike a tampon, you can wear our menstrual cups for up to 12 hours. #heavyflow #menstrualcup #periodtips
