    Had an older generation and bought a replacement due to battery issues. So far so good. Make sure to get it fitted prior to purchase. We were able to use previous models size.

    Love it, works great! Love the information that it provides. Will be purchasing another one, like that it does have a one year guarantee since many have said the battery life doesn’t last long. So glad they honor it

    Loved the ring and the in depth information it provided. I did not like having to pay every month and had to let it go sadly. The ring itself does run on the smaller side so i would suggest sizing up.

    I love using this for cycle tracking! I dont know how accurate the step count is but it seems pretty close to my apple watch. I also use it to record workouts so i can see my HR zones but i still use my apple watch as well. Definitely get the ring sizer to know which size to get if ordring online!

    I’m really impressed with my Oura Ring 4. The battery life is great, and it’s helped me understand my body so much better, especially my stress levels and recovery. I’ve come to really value tracking my sleep and readiness each day.

    Love this ring. Very interesting to see how I’m sleeping, breathing, my steps, how my body temp changes when drinking alcohol, etc. Definitely makes me more aware of what I’m doing and how it affects my body. The only downside is it seems to easily scratch on surfaces, but I guess scratches are to be expected when you’re wearing it 24/7.

    I got this for my fiancé and she has not stopped talking about it. She loves it. It shows her how well she sleeps and her exercise. She likes to watch her heart rate at different stress levels to see the difference.
