Definitely not worth your money This has to be my biggest Amazon purchase regret and I wish I could return it after 4 months of trying. It is so hard to use, hard to remember how to use, the app sucks, and this technology is not nearly as smart as it leads you to believe. You can’t track your period start days unless you remembered to take your temperature that morning and you can’t go back and update information from over 3 previous days so if you forgot to take it your temperature you’re screwed. You have to manually sync the Daysy to the app and the app to the Daysy- this is fairly straightforward but not something you’d expect from a €300 device. The app feels outdated and pales in comparison to competing apps like Flo. I sincerely do not know how this has 5 star reviews on every platform. If it were €20, it’s totally worth the money. Maybeeee €100. But €300 is ridiculous for how cheap it feels, how outdated it is, and how complicated it is. I seriously doubt this was even made by women for women.

Not easy to use Not easy to use. Not as insightful as I would have liked into my overall cycle health. Hard to know if it was worth it. Setting it up and troubleshooting the issues was not easy and can't say that I had a great customer service experience--not great return policies. I still think my Daysey is broken but now I'm stuck with it and no one there seems to care. Overall not happy with this purchase and think that the company could do better to with customer service, instructions on use, trouble shooting and warranty.

Very expensive mistake to purchase. I have been beyond disappointed with the Daysy I purchased. I waited very long to get the new version (their website said the wait would be much less than it actually was which screwed up our family planning with our doctor that we started based on the websites indicated ship date). It takes at least two tries to take my temperature every morning and each try takes over two minutes. It very rarely actually syncs with the app. I've contacted support several times and they've been rude every time. I am not the only one having issues but they still make it feel like it's my fault. Definitely not worth what they charge for it! I was going to return it but decided to give it a chance. Big mistake. I also take thyroid medication which apparently screws up the readings but isn't mentioned anywhere in the information so a doubly worthless version expensive device.

Choose Daysy Wow, where to begin. This device has changed my life. To have the option to not take a pill everyday and still have a safe, natural, effective way to avoid an unwanted pregnancy is remarkable. Apart from this, the staff behind Daysy offers exceptional customer service. They go above and beyond to meet your expectations. There is not enough great things for me to say about this company. Choose Daysy.

I already loved Daysy because she is a… I already loved Daysy because she is a great form of natural birth control and I've only had great experiences with her. The customer service team on Daysy just makes having her even better. I've only ever had amazing communication with them; they're so timely, kind, and mindful. I love supporting this company and the amazing product.
