    Make sure to buy the sizing kit first, to make sure what you buy will fit properly. I've been wearing this ring and using the Oura app to monitor my health. Pretty accurate and easy to setup. If you connect to BT often, the ring will need to charge more frequently. Solid purchase!

    My boyfriend loves it! I’m so jealous I want one for myself. Its features help track the things I’ve always been interested in knowing about (such as stress and steps) but I was completely blown away on how much in detail it went into for each category. The best feature in my opinion is the sleep category. It even tracks your REM sleep. Highly recommend it for personal use or for a gift!

    Have nothing but amazing things to say about Oura. Its expensive… BUT HEAR ME OUT. What is better than being in-tune with your body. 12/10 would recommend anyone. If you are hesitant because of cost, pull the trigger and thank me later

    Genuinely the best purchase I’ve ever made. My sleep has truly improved so much since getting my ring, something about seeing my previously poor sleeping habits really helped me kick it into gear. My only gripe is that I never get more than maybe 4 days of battery life since I’m a ring size 7 so I have a smaller battery. But it charges very fast so it’s not really a huge issue.

    Really insightful if you’re into health data! I also use Stelo to track my glucose and I love they are integrated together. Highly recommend wearing the sizing kit for 24-48 hours before purchasing!

    I like the Oura ring for its functionality to give me data on multiple statistics like sleep, exercise, daily goals achieved, and my periods. Best I like is it giving me reading content to learn more on different data points

    Great fitness tracker. I use it more for recovery and sleep metrics. The only thing I don’t like is the battery life is very short.

    Love that the ring is automatic. Definitely suggest getting the plastic rings to know your right size. Only gotta charge it once a week and I love that I don’t have to do anything extra and it gives me great insight to what’s going on in my body.
