    Pretty handy. I like the personalized insights, wish they were a bit more personalized and varied though. The subscription fee is unnecessary but at least is HSA/FSA eligible. Powerful at detecting minor changes, very sensitive. While it is good to get a visual summary of how your body is feeling to force yourself to be kind to your body and listen to it from time to time in a busy stressful life, I'm not sure if it biases me to expect that because I'm not at a 100% or have "minor strains" I'll be extra tired that day (chicken and egg).

    I absolutely love my Oura ring, I debated between a Oura ring or Apple Watch and I’m so happy I chose the ring! For the price vs a Apple Watch it has so much more functions

    I am loving the oura ring so far. I have an Apple Watch but this ring gives you so much more information without having to charge everyday and always have on when your sleeping ect. It gives you insight into your sleeping habits and how to improve. Plus many many more things. I wasn’t sure I would be able to wear it because of the size but I don’t even notice it’s on anymore

    It’s well worth the price I’m a 56 year ole OTR driver who doesn’t get normal meals, sleep schedules or stress free days due to customers and traffic so it’s nice being able to see what I need to focus on more during my hectic travels

    This Oura Ting is simply amazing! I am learning about my sleep patterns and how to increase my quality of sleep. I am able to use the data and learn how to get more deep sleep. Deep sleep rejuvenates our minds and renews our cells. I use the data to improve my sleep quality. I highly recommend this Oura Ting without reservation.
