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

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.

Best Purchase ever
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The Oura Ring helped me understand the quality of my sleep, not just how many hours I slept. By tracking sleep stages like deep sleep and REM sleep, I became more aware of how my habits affect my rest. Improved Daily Energy .The readiness score shows how prepared my body is for the day. This helped me adjust my activity levels and avoid burnout when my body needed recovery.

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.

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.

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.

||Posted . Owned for 1 year when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Skeptic at first but I really love my oura ring!

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.

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.

Great insights but battery life needs improvement
||Posted . Owned for 10 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I absolutely love the sleep tracking and daily vitals breakdown. I am in between a 10 and a 9 as far as size so I wish there were half sizes. I also wish the battery life lasted longer but I understand the mechanics behind why it dies so quickly. Overall I recommend it and I look forward to future menstrual cycle insights.

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!
