    Seems to track accurately, comparable to my apple watch. Realistic battery life has been averaging around 4.5-5 days between charges.

    Overall - I love it! The thing I will say about this device is that it is somewhat bulky- if they could fix that — I’d give it a 5. And maybe a couple other options — like white. The battery is good, the data is great, and it was easy to sign up and daily use it great.

    The sizing kit has me wearing a size 10 so I purchased that size. It was way to being and almost fell off several times.

    I love my Oura ring. It holds charge extremely well & I got the perfect fit using the sizing kit before purchasing. It has a lot of cool features. The biggest complaints I had and why I chose 3/5 stars is because it scratches extremely easy for it being over $400 and there are a lot of other smart rings that do not require a subscription.

    The Oura Ring has been one of the most impactful tools I’ve incorporated into my daily routine—particularly when it comes to improving my sleep and overall recovery. Before using it, I had a general sense of how I was sleeping, but no real data to understand patterns or drivers behind my energy levels. Oura completely changed that. The combination of sleep staging, readiness score, and personalized insights gave me a clear, actionable view of my habits.

    I really love this ring! The 4th gen lasts about 5-6days battery wise, which is very long in my opinion ! It does scratch, but thats expected with any piece of jewelry!

    Bought the Oura as an anniversary gift for my wife. She loves it. She’s been wearing it for a few weeks and speaks about how comfortable it is and how much data she’s able to collect and use on the app.

    I love that it tracks everything. Reminds ypu to stand up and walk as well as when its time to start getting ready for bed. I sized up 1 from my normal ring size. My fingers tend to swell so sizing up was a must for me.

    I like the Aura ring but don't wear it daily. When I wear it, it is accurate in tracking my health and fitness. It is also fashionable and blends in with other jewelry.

    I am amazed at what this ring does for me. I wised it would somehow alert things of concern. This is able to pick up changes in my HR and because of that I had a conversation with oh my doctor. Only thing is it does have tiny scratches. Must be careful

    This is by far one of my best purchases this year. Was looking for something to wear when I didn’t want to wear my Apple Watch, but it is slowly replacing it. The data is very accurate and comparable to data my watch captures. It looks really nice on and I receive so many compliments.
