Great product if you buy the right size.
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Great ring, Apon opening it nake sure not to place the ring on the charger incorrectly because it will get stuck. Also keep in mind that fingers do swell from time to time so try not to get a ring that is too snug to begin with if you dont plan on using the sizing kit to find the ideal size. This ring does a great job of tracking my sleep habits. Do be aware that it will get scratched if you dont put a protective band on it right away.

Hidden fees. Not “Wearable” for Half of Us
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.After three weeks of wearing an Oura Stealth on my index finger, I think until and unless Oura offers half sizes, this device should not be considered a “wearable” for many of us. I went to Best Buy to use their sizing kits and take advantage of helpful humans and same-day purchase. I was planning a trip in three weeks and wanted to test the ring’s ability to track health during travel. I found a Best Buy expert who said index is the preferred finger. A 9 was a bit tight but she said previous Oura owners were dissatisfied with results from other than a snug fit. I bought it. A week later I asked Oura Customer Service about the slight depression on my index finger and whether a ring finger is acceptable. Two days later I received a glorified AI FAQ (or rather, “FAQ off”) email with a name at the bottom to make you think a human actually spent time on it. “Naomi” said only that index is preferred and there are no half-sizes. In effect, suck it up. Even so I went back to Best Buy to size the ring finger and found a slightly better fit, but Best Buy did not have it in stock. With only a few days left before departure I decided not to risk mail order. Big mistake. I learned that fingers swell quite a lot during air travel. At some point I noticed the ring was chafing painfully. I put some soap on it to get it over the knuckle and applied it to the ring finger, where it now fit pretty well. The ring finger test lasted two days. It was looser fit and did not pick up data near as well as the index. At some point I looked down to see the ring was gone. Whether at a luggage carousel or washroom I don’t know. But good riddance. The ring was nice looking though not as sleek as my wedding band; worn on the dominant index finger it interferes a bit with pens and forks, but on the other hand it interferes unacceptably with fretting a guitar. I didn’t like the app. I wanted to check it upon waking to see how sleep went, and review activities from the previous day. Data download data from the ring takes long—OK, a tradeoff for small size and longer battery life, live with that. Pressing the top-tab for “Yesterday” takes me to a calendar from which I can select yesterday and see… today’s scores again. After fussing about in the menus I manage to find yesterday’s data curves but I’m still not sure how I got there, perhaps it just takes time for the app to retrieve the saved data from a server somewhere. Activity tracking is not intuitive. The app guesses your activity and asks you to confirm. Guesses well for playing guitar or walking—stationary bike not so well, I think because the accelerometer is not as engaged. The ring has only this, ten-minute interval heart rates, SpO2 readings and time of day as inputs, and uses some algorithms to interpolate from that. You can change the app’s guess about your activity by selecting from a list with “choices” including Finnish baseball but not, oddly enough, sex or sauna. I tried to use “Tags” feature as a workaround but the entry screen is unhelpful. I can choose Start and End times, but cannot compare to detailed heart rate graphs to refine when those happened. It takes three passes to save all three Tag data points. I got little from the analyses. It was told when I got to sleep late—I knew that without the app—but no advice on why REM and Deep sleep are consistently red, though I felt rested. (One poster on internet said he fixed his low scores but getting a different ring!) I saw interruptions in SpO2 that might mean sleep apnea—or one of five other things, like a poorly-fitting ring. I saw no info on stress levels (yet). I was consistently low on heart rate variability, which is supposedly a bad thing, but I felt fine. Maybe the ring needed more time to adjust to my personality. I was hoping to see if I needed the extra analysis provided by the add-on $5/month subscription but never did understand what was covered and what not. I see from Oura-sponsored research that Oura does a 5% better job at detecting sleep levels than other wearables; but none are as good as EEGs. Bottom line: expensive with hidden fees. If a perfect fit, it might work for you. Otherwise, until and unless Oura makes half sizes for the rest of us, their rings cannot really be considered “wearables.” Watch formats work as well for less money.

I think it’s worth it
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.My wife has been using it for 2 months now and she loves it. Literally talks about her stats everyday haha. Seems to be pretty accurate on a daily basis as well. The battery life also last for a few days and charges pretty quick as well. Overall, it was a great buy in my opinion and I plan to get one for myself as well now

Amazing!
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.love this so far! It is great seeing my sleep and activity on it, without have to wear a bulky watch. The charge lasts me about 3 to 4 days. If you aren't used to wearing a ring it does take a few days to get used to but other than that, perfect.

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

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.

Low key but Great
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I debated long and hard on getting one of these including several weeks of trying the sizing rings on various fingers (definitely a good idea). I finally made the purchase during the July Best Buy anti-Prime Day sale. It was a great choice. I have been wearing various smartwatches from Samsung, Garmin and now a Pixel watch 3 which are handy but not great for wearing while sleeping or during things like Yoga. The Oura ring is perfect for all of that and more. I stopped noticing it almost immediately but appreciate how much info I can glean from the app from sleep info to activity tracking. It's more than enough for my needs and catches more since I wear it pretty much constantly. I still wear the watch but use it primarily as an adjunct to my phone with the ring handling the majority of the vitals tracking. My only suggestion is to invest in some of the silicon ring covers you can find on Amazon just in case you are doing something (e.g. home renovations) where you might damage the finish.

Love It.
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It provides important health data so that you understand what areas need attention. This was eye opening to me as far as the quality of my sleep, my heart rate variability and my oxygen saturation. I purchased one for my husband after trying it because I love it so much. Also, it looks nice which I can't say so much about other health tracking devices.

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.

Very Helpful
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.As a nurse with POTS I find my oura ring to be something I can’t live without. It helps me interpret what’s going on with my body as i’m not the best at listening to when I should go or when I should rest. I will say it does scratch very easily but that doesn’t bother me. I love my oura ring!

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.

A Game-Changer for Sleep Tracking
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I absolutely love my Oura Ring Gen 4, it’s hands-down one of the best purchases I’ve made for my health and wellness. I originally got it to track my sleep more accurately, and it has completely delivered on that promise (and then some). The sleep tracking is incredibly detailed—far beyond what I’ve seen in other devices. I get real-time insights into my sleep stages, restfulness, heart rate variability, body temperature, and even readiness scores that help me understand how well I recovered overnight. It’s amazing to wake up, check the app, and have a clear picture of how I slept, not just how long I was in bed. Beyond sleep, the Oura Ring also tracks activity, recovery, stress signals, and daily movement, all in a way that feels personalized and intuitive. And because it’s a ring, it’s lightweight, discreet, and comfortable—I forget I’m even wearing it. The battery life is great too; I typically get several days on a single charge. If you’re someone who values sleep quality, daily readiness, or just loves seeing detailed health metrics without wearing a bulky watch, I highly recommend the Oura Ring 4. It’s more than just a tracker—it’s a powerful tool for optimizing how you live and rest.
