Almost perfect !!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Almost perfect. The reason of not having 5 stars is because the tracking of my heart rate while working out isn’t accurate at all, even when having the sensor facing my palm (tried even with tape so it won’t slide) I was averaging 110 to 130 bpm while on my other more accurate tracker I was between 150-170. I think if they fix that issue this will be a perfect product. Sleep wise is hands down the best product you can get and battery also last a long time

Buy it ASAP
|Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.[Employee of bestbuy] Do not hesittate. This has been the best health related item I have purchased. It tracks so much and learns your body the more you wear it. I use it with my Apple Watch to get the most accurate readings and its lifechanging if you care about tracking sleep, body temp, exercise, heart rate, body readiness, and so much more! I have no regrets. Yes, there is a subscription but with what you get out of the ring, I do not even care about it. Well worth everything.

Steve/Nicole's Review

Decent ring, but battery life went downhill fast
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been using my Oura Ring for about three months. Overall, I really like the design and how comfortable it is — sometimes I even forget I’m wearing it. The sleep tracking and readiness insights are helpful, and the app is easy to understand. However, the one big downside for me has been the battery. When I first got the ring, the charge would last several days. Now, barely three months later, the battery only lasts about a day before I need to recharge it. For something that’s supposed to be worn continuously, that’s disappointing and a bit inconvenient. The ring itself works well, but the battery performance hasn’t lived up to my expectations. If the battery lasted like it did at the beginning, this would easily be a five-star product. As it stands, it’s just “okay.”

Can't live without it anymore
||Posted . Owned for 7 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Was reluctant when I bought it as I did not think I really needed one but in fact, it is a life changer. I am improving my health by being able to observe every accurate detail of my life which would have gone unnoticed, from sleep quality, impact of certain foods and level of activity to body temperature and stress. The food diary is amazing with photo recognition, it even detects unusual foods with little to correct. I paired it with a glucose monitor and my Apple Watch.

Replacement for watch
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Because it’s a ring, it’s very discreet — no screen, no “watch” look. Compared to many smartwatches, having up to a week of battery is a strong plus, especially since you don’t have to “charge every night.

I bought it for my wife
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.She loved it, it's very functional. She doesn't even take it off to go to the bathroom, since it's always monitoring her sleep, heart rate, how many steps she takes a day, and it's very accurate in all those measurements.

Great Investment!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been using the Oura Ring for a while now, and it’s easily one of the most useful health gadgets I’ve owned. What sets it apart is how effortlessly it blends into daily life—no bulky screen, no constant notifications—just a sleek, comfortable ring that quietly tracks a surprising amount of data.

Worth the hype
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been using the Oura Ring for a little while now and honestly it’s become part of my daily routine without me even thinking about it. It’s super lightweight and comfortable, so I forget I’m wearing it most of the time. The sleep tracking is probably my favorite feature. It gives really detailed info without being overwhelming, and it’s actually helped me pay more attention to recovery and sleep habits. I also like the readiness score and heart rate tracking, especially on workout days or after long runs. Battery life has been solid and I don’t have to charge it constantly like a smartwatch. Plus, it looks clean and low-key compared to wearing a big fitness watch all day. Overall, if you’re into fitness, recovery, or just want better insight into your health without wearing a bulky device, the Oura Ring is definitely worth checking out.

Great device, unusual sizing
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I'll start by saying I've been wearing an Oura ring for about 5 years. I got the OG ring with the flat side. I had the Gen 3 previously and it worked well for me, I even got a replacement from Oura when the battery started to give out. After 2 years or so, I decided I wanted to upgrade to the Ring 4. I got the sizing kit since I hadn't worn a ring without the protruding sensors before. Originally I wore a 6 for the OG and it was a bit loose. For the Gen 3, it felt more snug. When trialing the Ring 4, I got a 6 again after wearing the sizing kit since Size 5 felt too tight for my pointer finger and OK on my middle finger. I previously could wear my Gen 3 on my ring and middle interchangeably and on either hand. My dilemma was I wanted the flexibility, but for this ring, 6 was too big and 5 was too snug. Ultimately after wearing both, I opted for the Size 5 and only wear on my middle finger. It was disappointing because I sometimes like I wear other rings and move my Oura ring to my pointer finger so it doesn't scratch, but I will just have to switch it up. For me, sizing down was best and I had to forgo flexibility because I was more worried about my ring sliding off. Otherwise, good build, I like how sleek it is, and though sizing is a pain I like the flat sensors, it doesn't leave marks or dig into my finger.

A Minimalist Masterpiece for Mindful Health
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Sleek, minimal, and deeply insightful. The Oura Ring is more than a fitness tracker — it’s a beautifully designed mirror into your sleep, recovery, and overall wellness. It helps me understand my body better, balance activity and rest, and make smarter daily choices. A powerful, elegant guide for anyone serious about health.

Love it!
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The app is easy to navigate. It did take a few days to adjust to the ring itself, but after that it was fine. I only need to charge it once a week and takes about 45 minutes.
