Changed my life for the better!
I never write reviews (who has the time?), but this product deserves one for being so remarkable. As soon as I finish writing this, I'm purchasing a couple boxes for my sisters, just so they can try it out. This product was NOT a freebie handed out in exchange for a review. I paid full price for it, and am so glad I did! PROS - Reduces cramps! It lessened my horribly severe cramps by at least 30%. For me, that's the difference between whether or not I can get off the couch. I used to curl up in a miserable ball during periods, but now I can function! - Makes my period last 4 days instead of 5! - Flex discs handle my heavy flow with ZERO LEAKS. (I used to be an "Ultra" tampon girl, so this is impressive.) Now I have peace of mind 24 hours a day, and it's so nice! My quality of sleep during periods has improved, too, since I don't have to worry about leakage. And I don't have to keep checking the status of things down there - I can simply count on my Flex disc to work, and it DOES. - There's so much less trash to take out, and no bad smells from the trash either! - The self-emptying design is brilliant. - So comfy, you forget it's even there. - This product is LIBERATING! I never realized how much hassle and energy went into dealing with pads and tampons until I switched to Flex. It's a huge weight off my shoulders! CONS - It can be a bit messy, but isn't every feminine product? Still, I'd prefer to use these when I have access to a private bathroom for handwashing. Thank you so much for inventing this life-changing product, Lauren!

worth the cost. better for your body.
Absolute game changer. I don’t like pads at all. Tampons were starting to make me feel poor and I didn’t like the chemicals. I tried the period cups but they hurt to go in and suctioned on the way out. I wasn’t sure what to do. My friend recommended these and I can’t believe how well they work. A little pricey but totally worth it for not putting chemicals in your body and making you feel worse. Suprisingly they didnt hurt to put in, though took a few tries to get it correct. First one didn’t last 12 hours but the after that they did. S*x was great, didn’t hurt me and my husband didn’t notice it there much. I do feel like it lessened my cramps partially due to not being made with chemicals. I do think I’ll need to keep lube with me in case I’m in public and can’t get it in. But I will absolutely never use anything else. I recommend to everyone

Changed my miserable life after 20 years of tampons
Monthly girl time was never a good time for me. Not that it's good for any woman, but I was always in debilitating pain every time I had mine to the point of vomiting and curling up dead in a corner for a few days. Heavy flow and cramping, and my cycles usually last 8 days compared to the normal 4-6. My mother had to put me on birth control at 15 to help with the pain. I never thought tampons would be part of why my pain was so bad. I had a tampon in the first day when these arrived in the mail, and I was skeptical, but I gave these a shot the next day because I'd read how they potentially could help reduce cramping. I've tried hundreds of products claiming the same thing with no success. The change was insane. The cramping is still there, but very much reduced. It's like the edge has been majorly taken off. I insert them as instructed, I squeeze it, keep the side with the plastic attached facing away from me as I put it in and push the bottom part up behind my pelvic bone. I don't even feel it in there. I tried twisting and moving around all kinds of ways after putting it in and it was surprisingly comfortable and didn't move or come out. To date I've never had leaks beyond what tampons had for me, so I do still use a pad as a backup (and you generally should if your flow is as heavy as mine has always been). I am able to reuse the same disposable ring for the entirety of my cycle and I toss it when it's over. When I go to the bathroom, I'll have some toilet paper ready and if I'm at home, I'll use that to move the ring to the sink. I clean up as normal and rinse the ring (and the sink) with warm water before reinserting it. If I'm out in public, the most I'll do is pull it out just enough to let it drain before putting it back behind my pelvic bone, but I usually don't have to empty it but twice a day, once when I wake up and once in the evening. After the first couple of days I can get away with only emptying it once per day. As far as mess goes, in my opinion it's the same as dealing with the heavily soaked tampons. There's really not much difference to me. I'm beyond happy to deal with a little more effort on cleaning the ring out in the sink for the reduced pain. Another major plus, it's FAR less wasteful, and it's durable enough to last an entire 8-day cycle without coming apart. With the 12-pack of these, I could potentially only have to buy them once per year! I bought a small pack because I was quite sure I was going to hate these, but I love them and wish I'd had them 20 years ago. My cycle has changed dramatically since using them. The flow even seems to be a little lighter. I've been using them for three months now and I never plan on going back. I came here to order another pack of these and look at potentially buying the permanently reusable one to give that a try, but I decided to leave a review first. Women of the world, I know it's scary and different, but give it a try for one cycle at least. I've given my stash of tampons away and will never buy them again. These rings have made my period time far less of a miserable sick time and so much more manageable with just a little ibuprofen that it isn't even funny. I feel like I'm finally living how I hear is supposed to be normal for women on periods. Just give it a shot. I'm really happy that I did.

I want to keep using them to get the hang of it!
This is an interesting product for sure! Just for some background on my cycle, I have an extremely heavy flow and I can bleed through a super absorbent tampon in twenty minutes, and I have awful awful cramps that leave me in the fetal position. Insertion: inserting it was easy and pretty self explanatory, though it’s kind of uncomfy when you’re putting it in only because it tries to take its circular form while it’s in the canal lol The 12 hours: like I mentioned before, I have awful cramps. I kid you not, minutes after I put the disc in my cramps subsided and eventually went away. I legitimately forgot I was on my period! I went about my day, and I had a few leaks. These leaks could have happened for a number of reasons, I’m new at this so maybe it wasn’t sealed or in the right place, maybe my flow was too heavy, or maybe I pushed subconsciously and allowed blood to come through..regardless, it leaked some. But the leakage was not enough for a pad, a panty liner is plenty for the small amount that came out. I couldn’t feel it at all, I went about my day really. I haven’t tried having sex with it in though so unfortunately I can’t review that aspect :( Removal: removing the disc was slightly challenging and very messy. This could also be because I’m new at this as well. It was hard to pull it out because the top lip of the disc sits behind your pubic bone so when you’re pulling it it feels like it’s not going anywhere. So then I started doing kegels to get it out and it worked! However, when you do the Kegel, the bottom bag part of the disc gets pushed up, so the blood that was once sitting in the bag gets pushed out and is now all over your finger and hand. If your blood bothers you and you have a heavy flow I wouldn’t recommend this product. Overall though, I think this is a really neat product and I want to keep using it to try and get the hang of it. Not cramping and not having to take ibuprofen constantly is just amazing to me. And not feeling it is awesome too! Like I put a tampon in after I had taken the disc out and I actually got sad because I could feel the tampon. And plus, the discs are less waste and doctor recommended! If you’re up for it, try the discs!

Game changer
I’ve been using Flex discs for a while now, and I can honestly say they’ve completely transformed my period experience. If you’re someone who struggles with heavy flow and cramps, these discs are an absolute game-changer. First, let’s talk about convenience. For someone with heavy periods like me, I used to be stuck changing tampons every 10-20 minutes during the first couple of days. It was exhausting, and I was always worried about leaks. With Flex discs, I can comfortably go an hour without worrying about leaks or needing a change. That’s a huge relief when you’re already dealing with the discomfort of a heavy flow. But the real magic, in my opinion, is how much they speed up your period. The larger capacity of the Flex discs allows the blood to pass through more quickly, shortening the duration of your period and making those tough days so much more bearable. I’ve noticed a significant reduction in cramping as well, which has been a huge plus. It almost feels like the discs take the edge off everything – less mess, less discomfort, and a faster cycle overall. It’s worth noting that there’s a bit of a learning curve when it comes to inserting and removing the discs. At first, it took me a couple of tries to get the hang of it, so I would definitely recommend practicing at home before trying them out in public. Once you get the technique down, though, they’re really easy to use, and I’m now able to insert and remove them with no trouble at all. When it comes to comparison, I’ve tried tampons, menstrual cups, and pads, and none of them have given me the same level of comfort and peace of mind that Flex discs do. They’re discreet, they don’t cause irritation, and most importantly, they actually work. I can’t imagine going back to anything else. For me, Flex discs are now the only period product I’ll use going forward. If you’re on the fence, I highly recommend giving them a try. It might take a bit to adjust, but once you do, you’ll likely find them to be the most effective and comfortable period product out there.

Leaks on heavy days, amazing on light
I'm so torn about these.... On all but my heaviest 2 days, these are 5 stars, amazing and life-changing. They catch 100% of my flow and only have to be changed every 12 hours. I'm not inclined to have period sex so I haven't tried that feature, but everything else is as good as advertised. 5/7 days of my period, I love these and only regret it was so long before they were invented and I found out about them. But then there's the heavy days... If you read the company's guidance or just look online, everything says if you have leaks, it's because you haven't inserted it correctly. That's simply not true. Of course if you insert incorrectly, you will have leaks. But that's not the cause of all leaks. I know this because it doesn't make sense that I would insert the disc correctly 100% of the time on my lighter days, but somehow magically forget how to do it right on my heavy days. It's not me. It's the disc. More accurately, it's the way the design works with female anatomy. The company guidance also says it's impossible for your period to be too heavy for the disc to accommodate, because no one's period results in more blood than the cup can hold. That is true only in the sheer mathematical sense that your period blood volume is less than the cup volume. But the reality of female anatomy is that the receptacle part of the disc is not sitting inside you all fully expanded like a cup. It's all bunched up and folded and stuck together with gummy period blood, so it can't open up to it's full capacity. The result is leaks. The blood gets around the seal (because while the product is somewhat moldable, you don't get a perfect seal). When the flow is light, it's ok because there is enough room in the receptacle part and it fills slowly enough it can accommodate. On heavy days, it slips around and past and when you stand up or cough or sneeze or poop or laugh, you get that familiar horrifying gush. One of the selling points of the product is the elimination of waste and need for other products, so it's very disappointing that I have to wear pads to catch the leaks on my heavy days. To me this is even a step back because before I discovered discs I used tampons. Pads take me back to junior high. I feel like a middleschooler wearing a bulky, bloody diaper. I hate the feeling of my period blood sitting against my body for hours. I hate pads. I suppose you could wear a tampon or a mentrual cup with these. If sex is possible, inserting other things into your vagina should be too theoretically. But then you're back to buying additional products, additional waste, and remembering to change every few hours (and not to pee on the string!). And if you're going to wear a tampon anyway, why not JUST wear a tampon? I keep using these discs because it's still more comfortable and convenient than anything else, even though they don't quite live up to what they're advertised to be. I just wish they worked as well on heavy days as light. If you have a light period, by all means try these. It will be a total life changer.

Disc vs cup: TMI things to know from a long time user!
First off, I’ve been using both cups and menstrual discs for years. They. Are. The. Best. I bought light “period underwear” for small leaks which I only have to use on my heaviest days. More on that later. Both cups and discs are cramp-free. Read that again. No more cramps. I don’t know the magic but if cramps ruin your life this information might just save it. Totally worth the learning curve! You also shouldn’t feel them while you are wearing them. If you do, you should try a different one, since not all discs/cups are created equal! I started my journey with another brand of discs which I could feel and leaked frequently. This one is the best one I’ve personally tried, but know if you’re built differently then perhaps this one might be problematic for you, while another brand works perfectly. Don’t be afraid to experiment. For heavy bleeders: discs are great for those first couple of days or so. They self-empty when you go to the bathroom, which means you don’t have to ever switch out period products ever again in public bathrooms. Truly, you only need take it out at the end of the day and replace it with a new one! Easy peasy. Beginner friendly since they are disposable. No washing or sterilizing like the cup requires. I know that really grosses out some people. Just toss it. Downside is, you will have to buy them monthly just like most other period products. Not so with the cup (there are discs designed to be reused as well but I do not personally have experience with them, and this review is about this disposable one anyway). Let’s talk disc leakage. It should be minor, unless it gets dislodged during a restroom break. This is my biggest frustration with discs. Sometimes it’s good, but it’s recommended to check its placement after using the bathroom since it sometimes gets out of its place. If you don’t catch it, then it won’t do it’s job. Since they are designed to empty out you may find they might leak with, say, a badly timed sneeze or cough even if it’s in properly. Even so, a light back up pad is normally all you need in such circumstances unless it was very full to begin with. If you feel a leak starting, head to the bathroom. Most of the time that means it is overfull. A light liner is usually all you need for these leaks if caught right away. To sum up: discs are not totally leak-free, but that is actually what makes them so amazing for heavy bleeders, since they freely “leak” into the toilet. Unfortunately they can shift during that process so it’s not totally set-and-forget it, either. Oh wait. Period sex? There is DEFINITELY a learning curve with this. Not so much leak-wise (though I wouldn’t try it if it’s full), but the guy can feel it. Keep that in mind and start slow. There was a BIG difference in this area between this brand and the other one I have tried. This one wasn’t as “sharp”, although hubby is still not a fan so I’m not sure I can recommend it. Cups! Cups are virtually leak-free in every sense with the proper fit. They are not nearly as “one-size-fits-all”: shorter, taller, wider, skinnier, firmer, and softer versions means you may have to try multiple brands and styles before you find one that’s perfect for you. With a proper fit, you should not be able to feel it. They do not self-empty, which means you have to take them out, dump them, and reinsert if they get full. However, in my experience by day 2 or 3 you can easily go all day without having to dump it. I’m a heavy bleeder. If you are a light bleeder, you should be able to use the cup from day 1 for a leak-free period. Outside of the initial “cavity blood” making its way out (the stuff that was already there before you put the cup in - quite minor), you could honestly go without a liner and be good all day as long as your bleeding isn’t heavy enough to fill it up. After day 2 or 3, I normally do this myself. I wear regular underwear and not even a liner for back up. That’s how leak-free it is. With a cup, there should be no sign of your period until you dump it out at the end of the day. No cramps, no blood. 5 stars. You do have to wash it, so “dealing with it” is messier in that sense, maybe. They say to boil it on a stove to sterilize it between cycles, but I find throwing it in the dishwasher works great (it’s only after I’ve already washed it, but if that freaks you out then do what makes you comfortable). I recommend owning at least two cups to let them “breathe” between uses: I don’t personally use the same one non-stop for 7 days even with proper washing habits if I can avoid it. To sum up: I hand down prefer cups over discs on lighter days, because I can completely forget about it all day. No “reminders” when I go use the bathroom. On heavy days, I sometime do a cup, sometimes I do discs. A disc and light liner is easy to keep in your car or purse if you’re caught off-guard while you’re out. That’s it! Hope this has been helpful. Always happy to share TMI if I think it will help out. Try these discs out, you will love them!

YOU WONT BE DISAPPOINTED
So this was a "hopeful" buy! I've never used a disc or a cup but I was so tired of tampons so after doing some research on these and giving them a try for a few days. I'll never use another menstrual product. They are easy to use/insert. You cannot feel them at all! SUPER convenient since you don’t have to remove them to use the restroom. This will be my go to from now on!!

Sono il top per uso occasionale
Il prodotto è un filino costoso. I produttori dicono che usato continuativamente consente di inquinare meno che con i normali assorbenti... Peccato che dovendone cambiare uno ogni 12 ore la spesa sia eccessiva. Sono però fantastici da usare occasionalmente per una giornata in piscina o per tutti gli usi che volete voi in cui il flusso crea disagio. Indossati, non si sentono affatto. Ci vuole solo un po' di confidenza con il proprio corpo, soprattutto per rimuoverli, ma secondo me battono le coppette mestruali su tutti i fronti.

Not for having fun with the partner
I bought the disposable discs because they were advertised as ‘mess-free period s.x’ and ‘barely noticeable.’ Honestly, I don’t see how that could be true. The ring is large, tall, and rigid, and both my partner and I could feel it, very uncomfortable. That said, I still find it a better alternative to tampons.

This ain’t it
Awkward. Uncomfortable. Will stick with a proper cup. Definitely can’t be used for intimate times during ones period, to avoid the messy clean up, as it has been suggested.. the ring is like the top off a juice container lol..
L**L
Worth it, fantastic device
These are amazing... cut my monthly pain down by 90%.... Super easy to use. I also gotba reusable dic applicator which also made making sure was in place a dream. Even while super heavy no mess, and easy to dump and clean up afterwards. 0 leaks... I actually preferred it to my diva cup I had prior. 10 out of 10... Will only use from now on.

Besser als Tassen etc.
Hält bei mir viel besser & länger als Tassen, Schwämme, Tampons, etc. Habe sie jetzt 2 Monate ausprobiert und an einem Tag hat es leider nicht ganz so gut gesessen, sodass ein bisschen Blut daneben ging, aber ansonsten hielt sie perfekt! 'Ne Menstruationstasse habe ich auch eine ganz Zeit lang getragen, aber die hielt nie so ganz dicht, sodass ich immer Binden, alte Unterwäsche und/oder Menstruationsunterwäsche tragen musste. Als ich sie das erste Mal getragen habe, hatte ich das Gefühl, sie würde überhaupt nicht fest sitzen, aber es ist nichts daneben gegangen! Ist bei mir grundsätzlich sehr viel leichter einzusetzen, als andere Produkte. Das Herausnehmen ist nur eine blutige Angelegenheit, vielleicht klappt das ja aber mit mehr Übung besser, idk. Nutze 1 bis 2 Discs pro Periode.
