I love my Daysy
I love my Daysy. Customer service is very is friendly and very helpful. I recommend it to all of my family and friends who are considering going off of hormonal birth control. However, there are some guidelines that must be followed for accurate results that some people may not be aware of. Most important thing is to be consistent. Take your temperature before getting out of bed in the morning (going to the bathroom first can throw off your basil temperature). The more consistent you are at providing daily temps, the faster the device can pick up your rhythm and provide you with accurate days of your cycle. It only takes 30 seconds to sync with your phone. Sometimes I forget to hold down the button on my Daysy to confirm my period and when I try to change it in the app it, wont input unless its done in that 24 hr time frame before you take your temp again. If this can be fixed, my Daysy would be more accurate with my cycle instead of thinking I missed a day in the middle of my menstruation week. Other than that, I have had no issues with my Daysy! I love the soft beeping sound when its finished taking your temp, compared to an obnoxious loud beeping alert like some other thermometers. All in all, worth the money and stays true.
