I’ve had the Oura ring for about 8 months now, and as my first device of this kind, I’m quite satisfied with it. The app experience is smooth and intuitive, and the ring itself is comfortable and stylish. I’ve found the health data to be more useful than I originally anticipated.I got the Oura ring to track my cycle and pair with Natural Cycles for contraception after removing my IUD, and it has worked well for this purpose. Additionally, I’ve found the sleep data fascinating, which has motivated me to adjust some habits based on the insights it provides about what impacts my sleep.When the battery life of my first ring declined to about 24 hours, I contacted Oura support. They responded immediately and sent me a replacement ring, which was very easy to set up and transfer, and it’s been working great.
