Gently used Daysy 2.0 Fertility tracker. Used it to help me pinpoint my fertile window to get pregnant and it worked like a charm! It is in great condition and has been thoroughly cleaned and sanitized. It will come fully charged, has been reset and is ready for pairing with your DaysyDay app. This Daysy will come with its original USB - Micro B charging cable, an additional longer cable that I purchased separately and a custom made crotchet cover for the Daysy! I will also include a manual with the package. Further details can be seen below or at the link addressed below. Discover your menstrual cycle – and your fertility!
