ONE RING TO RULE THEM ALLZZZZ…Kidding
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is a wonderful purchase and I couldn’t be happier with the product for my best-friend. This item has really changed the way she views her health and sleep quality. Thanks to this ring she’s able to fully track all of her progress through its app while also being able to wear something simple enough that isn’t too flashy. I couldn’t recommend this ring enough for anyone who just wants to simply track their heart rate and sleeping patterns as she struggles a lot with her sleep schedule. I swear the future of technology always surpasses our expectations.

It tracks sleep, activity, and readiness with impressive accuracy, and the design is sleek and comfortable enough for everyday wear. The battery life is solid, and the insights are genuinely useful.

Awesome overall healfh tracker
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is great, I work night shifts and I really wanted to track how much sleep i get, and the smart watch was uncomfortable so after some research I Ianded on the oura ring ceramic and nobody is thinks its a tracker cause i looks like actual jewelry. Plus added features like period tracking has been so great as well. If you're thinking of getting one; just get it. But sidenote if you want a fitness tracking device like running and such. This is not the product for you, check out Garmin.

Best purchase of the year!
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Ring really gives really good information on your daily activities. Tracks in real time, alerts you when you're idle gir extended periods of time. Tracks sleeping habits and much more. Really good for people recovering from major surgeries. Ask me how I know... lol. Best purchase I've made this year!

Love it!
||Posted . Owned for 7 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love my oura ring. Instead of wearing a watch each day, I was happy to switch to a ring. The charge holds for 5-6 days and measurements/data is extremely accurate!

Excellent smart ring with great battery life
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve had a great experience with the Oura Ring 4. It’s lightweight, comfortable to wear all day and night, and the battery lasts several days on a single charge. The sleep tracking is very detailed, and I also like the activity and recovery insights. The sizing kit helped me choose the perfect fit before ordering. Overall, it’s a high-quality product that provides useful health data in a discreet and stylish design. I would definitely recommend it.

||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I love the oura ring! I think so far my favorite thing is that it somehow knows i am getting sick before i do. I was notified to pay attention to how I was feeling as my biometrics suggested my body was under strain and I needed extra rest. 2 days later I was ill. That to me is fascinating. I also really enjoy the cycle tracking features, everything it measures for sleep, and how it somehow notices the difference between housework and exercise- but logs activity always. Pretty cool. I'd recommend oura to anyone!

Love the Ceramic finish
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I loved the Ceramic finish. It looks clean, doesn’t scuff easily, and comfortable to wear. I don’t have any complaint really. Oh one thing, I did not like sleeping with it because it was bulky and not comfortable to sleep with which beats the purpose. But I think the more I wore it the less I noticed it. I didn’t have it for that long because I upgraded to the 5. After having both even though the 5 is lighter I prefer the 4. The 5 to me feels cheaper.

Track all your data with the beautiful ring
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Love this ring! It’s beautiful for starters. It tracks literally everything you need to track. I wanted it mainly for the sleep data because Apple won’t fix their Apple Watch battery where you don’t have to charge it every night. The battery on this ring lasts for days. I would definitely recommend it to anyone!

Ceramic ring is gorgeous
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I absolutely love the ceramic ring! I had the Oura 4 in rose gold already and I much prefer the look of the ceramic. I was worried that maybe it would scratch easily but it is looking much better than my rose gold one ever did.

Perfect birthday gift
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Bought the Oura Ring 4 as a birthday gift for my wife and she loves it! Our whole family has been using Oura since 2024, so this was an easy choice. The ceramic finish looks elegant and feels great to wear daily. The Sizing Kit made getting the right fit simple — no guesswork. Sleep and activity tracking work perfectly. Highly recommend!

Excellent Insights
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I bought the Oura Ring for my husband, and it's been a great investment. It has helped him better understand his sleep patterns and why he often wakes up feeling tired. The insights are easy to understand and have given him practical suggestions for improving his sleep, recovery, and overall health. If you're looking for a wearable that provides meaningful data you can actually use, I highly recommend it.

Best health tracker
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Best health tracker I've ever had. I have the Samsung watch which is not as accurate. I tried a Hume band and it was not right for me. It did take some getting used to on my finger but it's amazing. Excited for all of the data to come through!

I wanted to love this, but I'm so letdown
||Posted . Owned for 3 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The pros: it's pretty confortable, it looks really sleek and polished, and it's far less bulky than wearing a smartwatch to bed to measure sleep metrics. The bad: customer service is AWFUL. You're forced to try and troubleshoot with an AI Chatbot that has the intelligence of a 1940s Sunbeam toaster. There are no contact numbers to call and speak to a real person. You can eventually get the chatbot to connect you to a chat agent, but even that isn't much help for the issues I've had with the ring. For starters, you have to pay a $6 a month subscription to use the ring. You can't do anything without the subscription. 6 bucks a month isn't terrible, but the subscription isn't worth it when the ring doesn't function as promised. There are issues with it missing workouts (the workaround they suggest? Manually record the workouts. As in, take your phone out of your pocket, open up the app, and tell it you're about to workout). That, to me, defeats the purpose and this ring is touted as being smart enough to automatically detect workouts. Mine has also, after the first 2 weeks, started missing HUGE gaps in monitoring certain metrics. We're talking 2 hour gaps where it didn't detect any HR data, chunks of stress monitoring missing, and also sleep data being incomplete. Support has suggested that maybe my fingers are cold (the gaps happen at random times, every single day). I work as a chef, so I can promise you my hands are not cold. They've said it could be that the ring fit is too loose. So, i tried it on a different finger - where it was so snug that it was almost uncomfortable. They've had me "soft reset" the ring multiple times (seriously, they pulled the "have you tried turning it off and on again?"!!). Everything they've suggested, I have done. Here we are almost 3 months later, I've paid for 3 months of their subscription and still have flawed and missing data. They are stumped, I keep getting told that they've escalated the issue and someone will contact me soon. Still waiting. But they did add 3 free months of the subscription service on to my account (allegedly) to help ease the sting of me paying a subscription for a ring that doesn't work. I don't have faith that they will admit that the ring is faulty, and that I am stuck with a $500 ring that barely does what it promised. Best Buy will let you return the ring within 2 weeks, however, my issues started 2 days AFTER that window closed. And getting Oura to admit the huge issues with this ring is next to impossible. So, I will save you the frustrations and forewarn you: the pricetag versus performance is not worth it. If you DO have cold hands/poor circulation, you will definitely have issues with this ring. I've also been told by others online that if you happen to have thicker fingers or darker skintone, you may also have issues with this ring dependably gathering the information needed. Others have said they have the same issue with missing workouts, with "no data" chunks for Heart rate and stress levels, and the symptom radar feature being totally useless and missing signs of strain impacting your health. I don't know if other smart rings are better, as Oura IS actually pretty accurate (when it DOES actually measure stuff). But, considering Oura is also far more expensive (considering the subscription and the hefty pricetag on the ring itself), I would expect it to be far superior too! I would not purchase this ever again. I'd rather have continued to wear my bulky Galaxy watch to bed (and dealt with the indentation on my wrist) and gotten more accurate readings and data and SAVED the $500+. Would not recommend.
