Life changing
These are a game changer. I literally tell everyone about them. The only disappointment is that they no longer work since giving birth! I haven’t figured out if I need to find a company that makes a larger size or if things are just different down there now. But, if you haven had kids, and even if you have - these are worth a try!

REALLY MESS-FREE during sex
I've been using these for the last three months and I was already very happy. It wasn't until my last period that I got to test them during sex, I was skeptical but I ended up super impressed, they are really mess-free! It was super comfortable as well, as if wasn't on my period at all. You can tell these were designed by a woman, amazing, thank you!

Can’t wait to try
Giving 5 stars before I’ve even tried it because all the 1 star reviews are from people who haven’t tried the product and only hate the ads because they are uneducated and hold toxic viewpoints on the natural events that happen to women’s bodies.
Yes, some people can and do enjoy sex on their period
Yes, you can actually put your fingers into your vagina
Yes, you can actually exit or skip an ad you don’t want to have to see
Yes, women have periods and no it is not disgusting or evil or dirty that we menstruate
So thank you for making an insightful and informative advertisement and creating a product to help us through a natural but uncomfortable time

Genuinely surprised and won’t go back
Got these with the expectation I’d have “mostly” mess free period sex, used them on day 1 and 2 with zero mess at all, almost spooky! I typically use a cup but now I am interested in trying the reusable disc! Will keep the single use one with me though.
Id give it 10/10 for sex, 10/10 comfort 9/10 for insertion (much easier than cup, no learning curve really), 6/10 for removal only since it was my first times and I couldn’t figure out how to not spill blood everywhere lol and it felt like it was so far up!! Still worth it, just will figure out a technique that works best for me :)

Perfect
I use this for overnights and genuinely super suprised at how easy it was to put in. love that i dont have to wakeup to change it. I will say I tried a menstural cup and it was wayyy to hard to put in but this was easy and breezy.
