Great product—highly recommended. So happy to be hormone free!!
Only issue I’ve had so far was glitch with the Daysy and DaysyView not syncing. I sent an email to their support team and within a couple of hours I got the information I needed to fix it. It was super easy!

I would not only recommend Daysy to people but I have become an advocate for Daysy! It's good for your body. There are no side effects. It's easy to use. It's empowering. Another bonus is their customer service team is amazing to work with. I will use Daysy for as long as I need birth control! Thank you Daysy for improving my life and my health.

I like it so far but I am not obsessed
I like it so far but I am not obsessed. I have been using it for like 3.5 months so far and it usually predicts my day of ovulation and period starting wrong. As with ovulation this is kind of annoying because then it won’t correct itself for a few weeks. Definitely makes you pay way more attention to your own body though which I love!

Hi Hannah, Thanks so much for your review. Daysy's ovulation and menstruation predictions become more and more accurate with time as Daysy comes to understand your unique cycle rhythm.

I would have loved to use Daysy
I would have loved to use Daysy. However, it is not recommended for women with irregular cycles or in perimenopause/menopause. Had I known this initially, I wouldn't have ordered it. Perhaps, this needs to be put in the details of the daysy for interested buyers.
Response from Usa DaysyJun 12, 2018
Thanks Jeana. Daysy is recommended for cycles between 19-40 days. When cycles go beyond that length, the user can experience a very high number of red and yellow days.

I absolutely love my daisy
I absolutely love my daisy. I take my temperature every morning and it's so easy and allows me to keep tabs on my entire cycle. I love being able to know when I'm fertile and when I am not and that I don't have to take any hormones to control my period. It's amazing to just be able to learn from my body the way it was meant to be.

Disappointed :(
I purchased my Daysy several months ago so that I could get used to it before my upcoming wedding. I decided to use the Daysy alongside the Fertility Awareness Method (charting). I love the size and the look of it, and so far it has measured my temperature accurately.
Unfortunately, I have a major issue with the app and data storage piece. There is no option to edit information beyond 3 days. Because of some incorrect data entered (I was unclear about when my period had actually started), I ended up having to reset the Daysy after 2 weeks. Since the Daysy takes some time to learn your cycle, I was a little unsettled to have to push the process back another two weeks. Additionally, even with the spacer for my iPhone cable, it takes a while for the Daysy to sync to the app. For a $330 item, I was surprised to find these issues.
I seriously considered returning the Daysy, but the return window is very short considering the nature of the product. On the Terms & Conditions page, it states that all returns must be completed within 30 days of receiving it. Up to 14 days, it is a full refund minus shipping. From 15-30 days, there is also a 10% restocking fee. Although I understand this from the company's perspective, it is also frustrating that I was already at the end of the return window by the time I fully realized the issues I was experiencing with the Daysy.
I'm hoping that my experience will improve over time, but as of now I am a bit disappointed with my purchase.
