Daysy rocks!
My original Daysy 1.0 was purchased in 2017, and I used it until our daughter was conceived in early 2020. This unit needed a repair to its case, which was performed at no additional charge; when I resumed use of the unit in 2021 postpartum, I discovered that the case had again cracked. When I reached out to troubleshoot, my contact promptly opened a ticket, got my device in for repair, and then let me know they were upgrading me to the 2.0 at no charge. Amazing and prompt customer service, and the device has been my faithful companion both as birth control and fertility awareness.
