Didn't know I needed it
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Friend after friend suggested an Oura ring, so I finally got one. It charges fast and lasts a very long time. I love the brushed silver but it does scratch. I wear covers on it while working out but still from ever day wear it has scratches. But the tech is great. I really would like a gold one with the brushed finish but they do not offer it. Sizing-wise I went one full size up from my normal size and it fits perfectly.

Almost perfect!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.The Aura Ring is a great device overall. It helps me keep track of my sleep, activity, heart rate, and overall health with impressive accuracy. I like how comfortable and lightweight it feels. I often forget I’m even wearing it. The insights it provides are very helpful for understanding my daily habits and improving my wellness. The only downside is that it tends to drain my phone battery faster, especially when I keep all the features connected for real-time tracking. That’s the main reason I didn’t give it five stars. Other than that, I’m really happy with the ring and would definitely recommend it to anyone looking for a stylish and reliable health tracker.

Oura Ring Size 15
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I really enjoy my oura ring! It helps me track my sleep and activities throughout the day. The biggest thing to me though is tracking my sleep. It lets my know if I get enough sleep at night or if I need to go to bed earlier the night before. For me I had to get the biggest size and prayed it fit. If they had a bigger size then the 15 would be great for people with big hands, but I took a gamble and prayed it fit and luckily it fit perfectly! I would recommend this product to anyone.

The Oura Ring 4 Changed How I Understand My Body
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I was skeptical at first — could a ring really replace a fitness tracker? After weeks of wearing the Oura Ring 4 in size 10, I can say: absolutely yes. The sleep tracking is incredibly detailed, breaking down deep sleep, REM, and light sleep cycles with surprising accuracy. I now understand why I feel groggy on certain mornings — and it’s not always about hours slept. The Readiness Score has genuinely changed how I approach my workday; on low-readiness days, I push lighter and I’ve noticed a real difference in performance and recovery. The form factor is a game-changer. As someone who works long hours at a desk and doesn’t want a bulky watch, this ring is comfortable enough to forget you’re wearing it — day and night. The battery easily lasts 5–6 days, which beats every smartwatch I’ve tried. If I had to mention one thing to improve: the monthly subscription ($5.99/mo) adds up over time, and I wish more features were available without it. But the data quality and insights justify the cost if you’re serious about health optimization. Bottom line: If you want deep health data without the bulk of a wearable on your wrist, the Oura Ring 4 is unmatched. I’d recommend sizing carefully (the sizing kit helps!) and committing to at least 2 weeks to fully appreciate the insights. Worth every penny.

Amazing product
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Absolutely love it. Got it a bit over a month now and I’m really happy with the statistics shown on the app. It looks good and it’s very comfortable to wear. Battery life is amazing. Have been going on walks and I feel like it calories burned are tracked very accurately.

Oura Ring Stands Out!!!!
||Posted . Owned for 8 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been wearing the Oura Ring 4 consistently for several weeks now, and I’m genuinely impressed. This isn’t just a health gadget — it feels like a sleek piece of jewelry that happens to deliver deep, meaningful insights into my body. Overall, the Oura Ring 4 is a standout in the smart-ring space. It balances elegance, comfort, and data robustness in a way that few other wearables do. If you’re someone who values holistic body insights (especially about sleep & recovery) more than raw step counts or GPS metrics, this is a fantastic choice.

Fantastic ring!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.It's honestly a great ring and great quality. It tracks everything super accurately. My main need for it was to track my sleep and I loved that the app would give you information on tracking like how well your body rested and recovered over night and how ready you are for the next day. It is very spot on. The charging also last for a week plus! It also synced any data I colleted to my apple health app which helped alot too.

Oura Ring 4 Stealth Gray
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I absolutely love my Oura Ring Gen 4! It keeps me on track with my daily activities and goals—especially when it comes to monitoring my sleep patterns. The insights have really helped me stay accountable to my wellness routines. The ring is incredibly durable, and the stealth gray color is beautiful—it has an almost black appearance that resists scratches (at least in my experience). I also appreciate how sleek and subtle it looks. One thing to note: the sizing feels slightly looser than the plate sample I used for reference, so I’d recommend keeping that in mind when choosing your size.

Love Oura
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Oura has given me insights on my sleep now I have a better understanding of my sleep patterns, another amazing about Oura is I can track my cycles especially my BBT body basil temperature and I don’t have to reach over and grab my BBT thermometer which makes it easier for me. I love Oura if you’re looking to track your overall health than Oura is for you.

Oura Ring
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love this ring. I’ve been wanting one for over a year and finally pulled the trigger on it! It’s been accurate and has helped me to manage my movement and stress levels from day to day. My only gripe is the sizing - i do wish it came in half sizes! Also, fully expect your ring to be scratched on day 1 lol

OURA RING IS A 10!
||Posted . Owned for 4 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great device to track a wide variety of physical activity and sleep parameters. Real time feedback and scoring makes this a perfect health monitor for anyone who wants to take control of their health. Impressed also with battery life lasting up to 7-8 days before needing to be recharged.

Good Product - Buy a Sizing Kit!
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great device, I recommend the extended warranty just in case (if you plan on using and wearing this everyday). The warranty will also cover replacing the battery within the period if it starts to wear out. Just a note, definitely purchase the sizing kit before hand! I originally did not think it would be needed but I was wrong and had to exchange my ring out. Good product so far :) I will also note that the matte can scratch easily (not sure about other colors, but the warranty covers scratches too)
