Easy to remove!
After trying several brands, this is my absolute favorite. Itโs easy to use, easy to remove, no leakage, soft material so i donโt feel the cup. So happy with this cup!

Best menstrual cup!
I love this cup! I have used the same menstrual cup for the last 10 years and I am so glad I bought this one. I will say i have tried other cups that I hated and stuck with the cup I had for so long. I wish I had tried this one sooner. I love that the stem is adjustable and that the ring is so flexible and soft. I had to cut the stem of my last cup because it was stiff and it would irritate me. This one doesnโt have that issue. Another pro is that the cup is stiffer, and seems to open inside easier due to this and stays in place. My last positive is the way it breaks the seal. My goodness, the suction can be so uncomfortable when trying to get a cup out. However, the way this cup breaks the suction makes it significantly better! I do think Iโll need to get the larger one as the small one doesnโt seem to hold as much (even though Iโve been using one of similar size). Overall, I highly recommend!!

Worth It!!
I honestly was very scared to try out this cup. I had previously tried using a different brands menstrual cup and it was a nightmare. I wasnโt able to get it out, and I had to go the my OBGYN to get it removed after having it in for almost 30 hours. But tbh before I realized I couldnโt get it out it was the most comfortable period of my entire life. I couldnโt feel the up at all, and it was like I wasnโt even on my period. So I was very excited to see this one had a pull tab to help you break the seal (which was the crux of the issue the first time around). Like most other people said, it is a bit of a learning curve and a lot different than other products I have used. Iโve seen a lot of people say itโs challenging to learn how to get in, but getting it out is easy. For me it was definitely the opposite, I was able to get it in within the first few tries, but pulling it out is still kind of hard. Breaking the seal is super easy, but if I donโt hold the cup a certain way I feel like Iโm getting torn in half when trying to pull it out. But like I said itโs a learning curve and honestly Iโm just ecstatic I can get it out myself lol. This product works great for me because Iโm not super familiar with my body, which made it hard for me to figure out where to reach and how to break the seal the first time a tried a cup. The pull tab was really easy for me to reach, and only took one or two tries get it right. I would definitely recommend this to people who want to try a cup but arenโt fully confident they could get it out or are a first time cup user. When it was in I didnโt leak and I couldnโt even feel it! So comfortable! Definitely worth it and saves money in the long run!

Easy to use
This is a great alternative that allows you to be more active. Isnโt too hard to use and itโs comfortable once you get the hang of it. Only downside is if itโs not in exactly right it will leak.

Click purchase now...NOW!!
Ladies, I am in my mid 30โs and I finally got the nerve up to try a cup. I have wanted to for a long time, however I always doubted myself. The what ifโs always talked me out of it. What it it gets stuck, what if it just pours blood out all over my pants, what if it leaks all day, what if it smells gross. Honestly the fear of it getting stuck up there was the biggest thing. I really didnโt want to have to go to by OB and say โOh hey hi, so I need you to pull this blood filled cup out of my lady bitsโ. I finally found this cup with the pull tab that breaks the suction for you and I was here for it. I purchased the smaller size and waited anxiously for my Aunt Flo to visit. The time came and I excitedly (and nervously) got that little black bag out and assumed the position (sitting on the toilet is best for me). It took some trying and experimenting to find the right fold for me, but let me tell you, once I got that fold down it was magic. I was kicking myself for waiting so long to try it! It is so easy to remove, I just sit on the toilet and pull the tab straight down and gently guide it down and it dumps right into the toilet. I then wash it with warm soapy water and put it back in. I usually have a pretty heavy period for the first three days and go through a lot of tampons and pads. Now I empty my cup three times a day on heavy days and twice a day every other day. I will say I tried the larger cup and it didnโt fit quite right for me, it is just a little too long for me, but the smaller cup fits perfect and I will never go back to tampons or pads. I always double check to make sure the cup pops open after I put it in to prevent any leaks but after my first period using it I now love it. My period doesnโt seem to last as long and it is no where near as heavy as it was when I used traditional products. I also have less/milder cramping. Ladies if you are on the fence I seriously recommend this cup and I think you will be like me and kick yourself for waiting so long!

Ok but could be better
I will be updating this review as necessary 5/20/20 First Iโd like to say I purchased this product after seeing a FB ad. Since I do not trust buying items from FB ads anymore I looked it up on amazon and made my purchase that way. I started using Menstrual cups about a year ago. I started with the cheap amazon ones that are about $16 for a 2 pack. I always buy size small even though I have naturally birthed a child. Initially that choice was purely because I was intimidated but since they work with no leaks Iโve continued to purchase that size. I say this because every vagina is different, just because you have birthed a child does not mean you need a large. If you have not birthed a child, that doesnโt necessarily mean you need a small. This can be a problem because $32 is expensive if you buy the wrong size not knowing what size you need. So I would recommend going with the cheap ones first. On FB some women expressed concerns about the stem of this cup hanging out. I too was concerned because on my cheapies the stem can be very uncomfortable and sometimes downright painful if I havenโt trimmed it enough! Flex assured everyone itโs a โvery soft silicone and you wonโt feel itโ I had my doubts but I am pleased to say that is 100% true. The stim does indeed stick/hang out a bit and I do not feel it at all until I touch it with my hand. Why only 3 stars? Because this cup was incredibly difficult to insert! I had to try 6 times and almost gave up! The stim is basically a plug and the plug is a thick piece of silicone that connects to one of the sides of the rim, innovative design for sure but it makes it difficult to fold the cup properly for insert and it kept popping open on me before insert or halfway through. Very frustrating. Iโm not even 100% sure if itโs placed properly right now so Iโll have to wait and see if thereโs any leaking. Design Softness What I imagine will be easy removal All give this a star Difficulty folding Difficulty inserting All subtract a star. I most likely will not be trying the rings. This is largely due to the fact that every OB Iโve ever had talks about how high my cervix is and how difficult it is to reach/see... if a doctor canโt handle it, Iโm reasonably sure I will not be able to reach all the way up there to pull the ring out when necessary. I purchased the kit because it was the same price as just the cup, I will be giving the rings to some friends who wanted to try them out

My Holy Grail Product
This is probably the best thing I have EVERRRRR bought myself!!! I have been on my period/spotting for 4 months straight due to Nexplanon and the Flex Cup has saved me so much time and money itโs not even funny. I feel much more hygienic without a tampon string and not having to dispose pads/tampons. I use a 7-fold and only have to empty/clean when Iโm home at my own sink. I originally bought this because other menstrual cups I tried got stuck and caused me to freak out. My cervix is stupid high and I could not get my finger in the position to break the seal (like not even a slight chance that was happening). The pull tab on this works exactly like a tampon and breaks the seal for you!! I bear down a little and weโre good to go. If any of this sounds appealing to you do yourself a favor and get this cup!! Iโm not a bot just a girl whoโs life has been changed due to this piece of silicone!!!

Pretty decent!
First time using a menstrual cup and I am 80% please with it! I say 80 because the only issue I have with it is *sometimes* it leaks when itโs โfullโ, even though when itโs removed, itโs only about 50% full. I use a panty liner with it. So Iโm assuming itโs because of the angle Iโm personally in (sitting or laying) opposed to just standing up and just letting it fill, if that makes sense. And the other issue is when I go to remove it and pull the โstringโ, idk if blood comes out of the hole when the string is being pulled down, but it can get MESSY. So much so that I honestly wouldnโt use this product outside my home, and thats a bummer. I sometimes have very heavy periods now, (thanks to my kids! Lol) so heavy I need to change a super plus tampon every 45-60min. So when I use the cup, I change it every hour and itโs always messy, until the end when itโs already spotty. I should also say, I do not sleep with it when my periods are heavy. Iv been using it for about 3 months now and Iโm sure Iโm using it right, but itโs still messy. Which isnโt an issue when Iโm at home, but again I wouldnโt honestly use this when I go out. You need to empty it, wash/rinse it, wash your hands, then reinsert it, wash hands again. I donโt see how you can do that in a public restroom. But for at home, it does do the job itโs intended To do. Now for the flex disk, it went in easier than the cup, BUT I must have a short V, because I felt it hit my cervix and it felt so weird trying to push it in enough to get behind my Pubic bone. But once it was in, I was good. Although idk how people could have sex with it in, itโs not THAT comfortable. Now removal.... with the cup, you pull strait down and catch the cup in your fingers and dump it, this disk, you need to hook with your finger and pull out under your pubic bone. Well....... I couldnโt hook it! Lol I was so scared but eventually I did, and since you have to hook and pull down and out, ALL the blood poured out and ran down my arm. Talking, Carrie prom scene. I scared myself lol. Luckily I was home and it fell in the toilet. Also, I never used the disk again since it came with 2 ๐. But it was nice to try something new! Even though the cup is a little messy, I think I will stick to that and using a liner, since it cuts down on period product cost monthly! Also, 2 things I do love 100% is that itโs black and wonโt stain, and the O on the string to put your finger through to pull! So all in all, 80% love the cup.

Amazing Product- Excellent Customer Service
This product is Amazing! Now I don't mind this monthly occurrence anymore. I have been a long term tampon user and gave this ago. It's so nice and flexible and soft and easy to insert. It really works. It lasts much longer than a tampon so going out and avoiding public toilets becomes a possibility. It is better for the environment too. It will last a good 10 years and replace a few thousand tampons and pads. Keep playing with the cup until you find the right spot for your body. I still use a tiny liner for those minor stains that may result from moving or running - a single toilet sheet will do the job too. After the second time I used my blood clots stopped and now the flow is so easy. I recommend the full cup for anyone. Better to wear it all day long rather than having to change half way. Customer service is excellent. If you need support just email them and they give you plenty of tips. Packaging is lovely. I have been giving them to my friends as gift to encourage better environmental footprint.

Best Menstrual Cup Ever!
I have been using menstrual cups for over 10 years now and I absolutely couldn't imagine going back. I have one that I prefer and it's getting old and needs replacing, so I read about alternatives and I found Flex. I can't tell you how impressed I am! The stem is easy to find and very flexible. It is also moveable and helps break the seal. Other than writing an essay to explain it all. Just buy this one. you will never buy any other. Its quite literally the best menstrual cup I have ever tried by FAR and I've tried many! I would like to sincerely thank the designers on such an amazing job and making women's life easier.

The pull tab is a game changer for those with a high cervix
I recently purchased my first ever cup and it was a traumatic experience. It made its way really high and was impossible for me to get out. I saw that this flex cup had a loop that you could pull to remove so I thought I'd give it a go. I've managed to remove it easily each time, even when it has decided to move really high. Such a relief! I've knocked a star off just because it does get a little messy during removal due to the hole. It's worth remembering that you shouldn't pull too hard as you end up pulling the plug through. Honestly though the small mess is worth it compared to the embarrassing removal I had with my first cup!

It works when it works, when it doesn't...
Beginning with this was a bit hard. I've been using cups for over 10 years at this point and this has it's pros and cons . +It's easier to remove +It's quite easy to clean +It doesn't feel if it's inserted correctly -it's prone to leaks -if you pull it out too hard, the pulling "cord" gets stuck

It got distorted.
I used it for one whole period. Now after the second period, the cup does not want to return to its original position. It just sits like in the pictures - no matter what I do to turn it back how it was. Maybe I am too agressive :D If this was a normal cup without the "patented stem", I could still use it, and now I have to look for a new one that won't distort. It ended up nicely in the trash, where it belongs.
