Better than all of the other options!
Life changing! I tried using a cup many years ago and no matter which one I bought, which size I used, it was too painful for me. I get toxic shock if I use a tampon. My period will stop and I’ll have to pull out a dry tampon. So I definitely can not use those. I have been using these Flex disposable discs now for probably 6 years. I love them! I tried to use a reusable disc (not flex though it’s too expensive for me) and it too was very uncomfortable. Not these though. I don’t even feel these! They are very comfortable. My cramps aren’t so bad anymore either. I do wear a pad or liner though. Depending on how heavy my period is, it will eventually leak. Not for several hours usually though. They do self empty when you sit on the toilet. Unfortunately though when it gets full, as soon as I sit down I find out it is full. Because it leaks out. So I find it necessary to always wear at least a liner. There’s no telling when it’s full. It does take many hours to fill up most of the time. Regardless of that I can not go without them. I’ll deal with a little leak once a day, versus leaking out all day long. So worth it!

My personal amazing experience!
⭐️⭐️⭐️⭐️⭐️ LIFE-CHANGING! I have been a tampon user for YEARS and honestly thought I'd use them forever. After learning more about some of the potential risks associated with tampons, I started looking for alternatives and decided to try the Flex Cup. Unfortunately, cups just weren't for me—I found it uncomfortable and a little painful to insert and wear. Luckily, the disc that came with it completely changed my experience. It was SO much easier to insert, and once it was in place, I genuinely forgot I was even on my period. I wore it through my normal daily routine, including long shifts at work, and had ZERO leaks. After seeing how well it worked for me, my boyfriend surprised me with the reusable version, and I've had the same amazing results. Only slight downside of the disc is that removal could be a little messy at first, but honestly, the overall experience of it is worth a little mess! For me, it has been a total game-changer. No more pads, no more tampons, no leaks, and so much more comfort. I only wish I had tried it sooner! Writing this in hope someone else feels the same way I do hehe :)

make the switch!!
i never leave reviews, but this is only my first day using my disc and i do not have enough good things to say about it. i purchased this because two of my friends brought to my attention that tampons have a lot of toxins in them, and there have been recent studies that suggest that they can cause infertility. they both use the diva cup, but i did not imagine that being something that would work for me. i think i saw an ad for this on tiktok, and the comment section convinced me that it was worth a try. first of all, i was very intimidated by installation. i thought there was no way i would be able to easily get it in place. i stand corrected. i attempted for the first time this morning while i was rushing to get to work, and it was almost ridiculously easy. it takes no effort to place it exactly where it needs to go. i am on day 1 of my period (therefore the heaviest), and i have had zero leakage. the self emptying feature did take me a couple of tries to figure out, but i found that if i lean forward while pushing, it works super easily. i also usually have VERY bad cramps, to the point where i feel like i can barely move. the absolute most i’ve had today is slight discomfort, and i cannot feel the disc at all. i don’t know if it’s the fact that i don’t have a tampon in, if it’s because the placement of the disc relieves cramps, or a combination, but either way, this is the first time in about nine years that i haven’t had a painful cramp on day 1. i will absolutely never go back to any other product, this one has completely changed the game for me!

The best disc you'll ever use
I started using discs a few years ago after I got an IUD. Before that I used a Diva cup. Initially, I was so frustrated. It took me a few cycles to really understand where it needed to sit, and even after that I would have issues with auto-dumping when I sneezed or coughed, or when sitting up after sleeping through the night. I tried a few different brands, really just cheap generic discs, and always selected the smallest size since I haven't given birth before. A few months ago, I made the decision to remove my IUD because it was causing massive bleeding for at least a week every cycle, but wanted to continue using a disc because it really is amazingly comfortable and easy to use once you get used to it. I've seen the Flex disposable discs and have never used them, but was drawn to the reusable option because other reviews said it had a firm rim and a good standard size, and lord were they correct. This disc is amazing. I know some people might hear "firm rim" and think it sounds uncomfortable, but that couldn't be further from the truth. Because it doesn't give, it stays perfectly tucked into place even if you move around a bunch or tense to sneeze or cough. It also makes it easy to know that it's back in place after you go to the bathroom, because you can literally feel it "pop" behind your pubic bone with your fingers. Trust me, you will not feel it inside you. And because of the little notch in the rim, it's even easier to fold and insert than a standard reusable disc. I've never had any issues with wondering if it's fully opened. My period was still ridiculously heavy for the first cycle after I had my IUD removed, but even now that it's returned to a much more manageable flow, this disc is a dream come true. I can't say enough good things about this. It's made my periods feel like no big deal, which was not always the case. And yes, it does result in less cramping than you would get with a tampon. I'd recommend it to anyone with a period, whether it be your first or your hundredth. My grandma says "they've finally found a cure for periods"!

Worth it!
I made the decision to switch to this back in April I think, and I would say I am happy with that decision. I previously used tampons and while I never had any medical issues using them, I know that they are horrible to put in our bodies and they are expensiveeeee. The reusable disk is top tier because 1. I don’t have to spend any money on tampons anymore, 2. The disk doesn’t make me skip certain activities like swimming etc., or sex. And it doesn’t slow me down, meaning I don’t have to be mindful about the time I last put a tampon in to keep track of when I need to go get a new one, I don’t have to think about what I’m doing and plan ahead to pack enough tamps to bring with me etc. It did take a couple cycles to get used to, at least for me. Figuring out the mechanics, so to speak, with how to insert the disk (the instructions and tips it came with helped!) how to ensure it empties itself the way it’s designed to and it took a few tries to see how to keep any mess bare minimum or non existent with removal (because you’re only supposed to leave it inserted for up to 12 hours). With cleaning, I do this after removing it when it’s been used for the whole day/night and I just clean it by hand with antibacterial soap, making sure I washed my hands beforehand and after also. The most helpful tip I found in reviews was to wear a panty liner for the chance a leak happens, avoiding any stains on your underwear, especially at night it helps with sleep. Overall I have no regrets with making the switch for my cycle. This has been great. ***Though I will add a disclaimer and say that I’m not sure this would be as mess free or leak proof if you have a super heavy cycle. Mine has never been super heavy, typically only lasting about 4-5 days and when I used tampons I would primarily use “regular” or “light” and periodically need “super”.

Comfortable and don’t leak
These are the best product out there. Period 😂 they’re comfortable. You barely feel them. They self empty when you use the restroom so they rarely leak and you only have to change them every 10-12 hours. I’ll NEVER go back to tampons. Ever.

Ptsd from the removal process
Easy to get in, minimal leakage! I have a heavy flow and so day 2 required extra trips to the bathroom. Once its in place, you cant feel it. My complaint is that taking it out it out is almost traumatic! "Hooking" it make the content leak out instantly which you can imagine the mess that comes with it. Other than the removal process, Im impressed!

I bought it because it was clear and undyed! And loved it!
I feel like I should rate it four stars because there is room for improvement, but there are so many pros, I don't really want them to panic and change it too much. Used the Nixit for several years. Took a break because I had my fourth baby. I loved a disc but to be honest it lightly leaked especially on super heavy days. Not always, but unpredictable spotting or nothing, so you really need a light pad with it. I have vulvodynia so the slightest irritation is like the end of the world in terms of hygiene products, rubbing, pressure, stems etc down there. Pads literally make me sore and aching skin within a couple days, they also are messy and have an odor and you can't wait to shower daily because you feel so unclean. I have used tampons but they come with a lot of risk, they are hard to gauge, too much absorbency and you get the dry tampon removal experience, or too little and it is leaking and sopping, plus that string is not just a little gross hanging around waiting to collect bacteria and infect you. I used cups for a while but they are not great with vulvodynia and you can end up feeling pretty desperate and raw by the end of your cycle even with stems trimmed off. Also getting suction every time when inserting can actually be tricky and you can really be in a panic on the toilet trying five and six times over and over, nope it is pushing itself back out, nope, slid out, why isn't it working, three different folds etc. At night is fine because you don't walk around so no friction or disturbance in suction from activities. Also, have you gotten it suctioned way up so you can't get it out? I have and my husband had to be called for assistance and even then we almost didn't get it out. Scary. Well after my period returned five months postpartum, I got the Flex reusable. I was looking for a disc that was clear to avoid dyed silicone. It is amazingly designed (yes I bought it not a paid promo). Compared to Nixit- Nixit is pink silicone, Flex is clear (much prefer clear, many people hate it but honestly 1) I want to see to clean it, not like a navy blue cup or tie dyed pinks and reds so you don't even know what you're washing 2) there is nothing we know about silicone colorants, the v is acidic can it eventually leach after being inside for days and days every month? one brand has cobalt titanate to color the disc and I looked it up and in pubmed there is currently carcinogen concern over the use of that even for medical device colorant but FDA currently still has it approved for use, not fussy about using a potential carcinogen near my cervix, sure the clear might yellow a bit but literally who is going to see that and I cheerfully trade it off for more safety assurance Nixit is about the same size as Flex in diameter, not noticeable Nixit is a thicker silicone material, Flex is incredible slim and streamlined and the pouch on the disc is like silicone Saran wrap Nixit has a double rim leaving a groove in between the rims, Flex is smooth (I do not like the groove because it is hard to clean gunk out and I have to run my nail in between or stuff actually builds up in there, yuck) Nixit rim is very soft and squishy incl rim, Flex is very soft and silky but the rim is firmer and springier more effort to pinch Nixit doesn't have a notch in the rim, Flex does (get rid of the notch! It doesn't help insert it at all and actually causes more twisting and difficulty and is a hard firm tip instead of a firm rounded insertion point. In fact it twisted so badly and folded up all over the place and turned into figure 8, I contacted the company and they said try turning it around so notch end goes in last not first in and ha, it worked) Because the rim is firmer on flex, I have no way to compare but people who aren't as stretched out inside as I am from birthing large babies might be a bit daunted by getting it in and accommodating it. I might be wrong though but somehow it seems more substantial inserting it than Nixit. Nixit is easier to insert in my opinion, the rim is firmer and the bottom is so silky on Flex it is actually a bit tricky to pinch the two sides together without one side trying to already twist under the other. Nixit leaks some because it is so soft it just must bend too much with activity. It is quite quite good and I still don't mind wearing it but don't do it on a heavy day, or you just should accept lightly leaking on and off at random. I am insanely impressed how despite all it has to do, you put the Flex and if you got it right, it is IN and you can confidently wear no pad on a heavy day. I farm, I was chasing escaped calves. I mowed. NO LEAKS. Except please be careful because I was on a heavy day, and was so enthralled by the Flex doing it's job I didn't empty it (sometimes it will auto dump but sometimes not if you don't do #2), I went 8 hours between emptying, I sat on the couch strangely maybe cross legged or on one leg and heard a sound and bled thru everything. I think it dumped on me. You can wear both when going #2, but you'll prob want to check with a clean finger it is back up under the pubic bone after. Nixit is more likely to sag down more. Nixit removal is like a blood bath. Flex there is a small amount of extra blood but I think the thin thin wrinkly silicone pouch part somehow collapses in on the blood and mostly contains it while removing it. I don't care about blood with removal, just grateful it wasn't in a pad and on me but it definitely is a plus to have less of it all over when removing the Flex. I haven't slept with it in yet. I have tried the Nixit and once I couldn't pee when I got up in night, and got so scared I never wore a disc at night again and use a cup (saalt soft). I tried last night for first time in a few years and I had been sore on inner pubic bone from trying to get the Flex in repeatedly and failing plus the notch nonsense (it was like my anatomy had shifted, low cervix??? Trick is relax, push down low with the disc and aim down towards tailbone to almost scoop under cervix. ). Lying down didn't feel good with the rim on sore spot so I took it out and wore Rael depends disposable organic underwear. I'll try the flex at night next. So far the Flex isn't causing urine retention or any discomfort even with my vaginal pain issues which is pretty something in fact. Hope this lengthy review helps you as I have others' reviews. So far I'm favoring the Flex reusable disc right now. Nixit is ok but it is less iron clad in my opinion in terms of leaking. I feel like nothing is happening when on period and wearing Flex. Clean, dry, not sore, no cramps, no sick feeling in stomach, and can keep a social calendar without wondering what awful gross bathroom you'll be forced to carry out tampon removal and pad changes, could even wear a white dress and not worry at all. (I would always still wear backup if I wore white lol). But having to change it every few hours or be worried about tss or leaking everywhere is great. And please do not ever get rid of the option to purchase clear undyed color style. Flex is the only one on market with a clear disc!

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.

Incredible
Couldn’t recommend it enough. I’m 28 and have never used a tampon, or cup in my life - pads only, so this was a completely new, and somewhat daunting experience. I was scared it would get stuck inside, which is the reason I never bought a cup, but this one seemed less likely to create a hard to break suction and get stuck, so I went for it. I definitely struggled the first couple tries to get it in properly, but on my 3rd attempt I did it perfectly and now have no issues. I have no leakage, I can’t feel it, and if I didn’t experience pain (I have Endo) then I wouldn’t even know I was on my period. Absolute game changer, sucks I’ve spent 14 years menstruating without this lol. Only downside is price, however I would pay that all day long for the benefits, and it is a bit messy changing it, but you only have to do it once every 12 hours, so it’s no big deal having a bit of a mess twice a day. And it’s super easy to take out which was my biggest concern, will never use another period product again

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.
V**A
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..

Only One That Works
I’ve tried a few menstrual discs and some I’ve had sporadic success with while others I’ve had no success with. Period products aren’t something where sporadic is “good enough”. I had always had great luck with the Flex disposable menstrual discs, but wasn’t thrilled about having to repurchase every couple of months and the resulting waste, but it took me a long time to bite the bullet and buy the Flex reusable disc because compared to other menstrual discs, it’s pricey! But I’m so glad I finally bought it because this is the only disc I’ve used where I have reliable success with it every time. No problems with insertion unlike other discs I’ve tried where it may or may not go in properly or at all. I’ve you’ve been frustrated by other reusable discs, spend the money and get the Flex!
