    The Oura ring is amazing keeping you informad about your health and habits. The app is great, and tells you how to improve your health. The only think I will have to deal now is the warranty since the battery is lasting a day and a half after less than 10 months of use and it was lasting 4-5 days.

    Easy to wear and provides good information regarding health stats. Only negative is that it will naturally get scratched with every day wear.

    This tracker is very accurate. We have compared it with other watch trackers and it's the best by far.

    I got this to track my cycle and my sleep, and it has been amazing so far! My watch has to charge every single night, so I can't track my sleep. I love that the battery life gets me to about a week so I don't have to worry about charging it every night like I do my watch.

    I love the data I get from my oura ring, it gives good insight to health trends and notifying if I may be showing signs of getting sick. Takes a few days to get used to the thickness of the band but I’m no longer bothered. Definitely size in store prior to purchasing

    Super happy with my purchase. I bought it during the Black Friday sale, which helped me save a couple of bucks. Sometimes it's good to treat yourself to things, and I'm so glad I bought this gift from me, to me :)
