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.

Awesome expierence!
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I was extremely pleased that Best Buy had the ring sizes and colors available so that I could make my decision quickly. I ordered the pink ceramic ring and received it in a couple of days. The process was seamless and I haven't taken the ring off since. I would definitely go back to Best Buy for all of my electronic purchases.

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.

Must Purchase if Looking to Monitor Health
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I’ve been really impressed with the Oura Ring. It tracks my health in a very advanced and detailed way, especially sleep, recovery, and overall readiness. One of the best features is how accurately it can predict when I’m about to get sick. I often get early warnings before I even feel symptoms. It’s comfortable to wear, easy to use, and the insights feel genuinely useful rather than overwhelming. If you’re serious about understanding your health and catching issues early, this ring is absolutely worth it.

Helpful and Stylist
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I added the Oura ring to monitor my sleep and stress. I was skeptical at first but enjoy the data insights the ring gives me. It's easier to sleep with and feel the ring does well with monitoring my sleep and stress patterns. The ring has given me better insight into my day and night and how it impacts my overall health. I highly recommend the ring. I love the ceramic because I was concerned about the ring getting scratched through daily use.

Loving This Midnight Color on the Ceramic Oura
||Posted . Owned for 2 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I upgraded to the ceramic mostly for looks. Yes it's less prone to scratches, but honestly, my brushed silver didn't have many noticeable scratches in the year plus I wore it. Is it worth the extra hundred, likely not, but I do love the Midnight color so I splurged. As far as battery life, it's comparable to my previous Oura Gen4. I feel like it's holding it's charge somewhat longer then the old ring did when new, but it's hard to remember. Unfortunately, my old ring was no longer consistently syncing, about every other day, and was three months past it's one year warranty, so I had to buy new. I just don't know enough about the other brands to not go with Oura again. Hopefully this one outlasts the first. As far as performance; this ring is fantastic at tracking sleep and that is primarily what I use it for. It also does a good job tracking steps, activity, and for women, your cycle and even your menopause journey if you choose. To me it's worth the $6.49 subscription but everyone has to choose for themselves on that!

JUST BUY IT...
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.After hearing about the Oura ring and all the data it can collect through just being placed on your finger, I was instantly interested. Originally, I was most interested in their partnership with Natural Cycles because I have been on birth control most of my life. I got pregnant with my daughter pretty quickly and as soon as she was born 2 years ago, I got back on birth control.. because, lets be honest ladies, I don't trust my husband when it comes to that... My birthcontrol will be expiring in the next year, so my hope is my ring will have enough data to help me use the natural cycle subscription to track my cycles and continue to prevent pregnancy. I am also an advance practicing nurse that takes pride in my health through weight loss, nutrition, sleep habits and so much more. This ring has helped advance my skills of understanding my own body and habits and my own health. I will be using this ring for the rest of my life.

Stylish Health Tracker I Wear Every Day
||Posted . Owned for 5 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.absolutely love my Oura Ring 4 Ceramic — it’s quickly become my go‑to wearable. The ceramic finish looks incredibly sleek and feels premium, so it doesn’t look like a gadget but like fine jewelry. The comfort is excellent, and after a short break‑in period I barely notice it on my finger all day. What really stands out is how accurate and insightful the health tracking is. It monitors sleep, activity, readiness, stress, heart rate, and more without needing a bulky smartwatch, and the battery life lasting several days means I’m not constantly charging it. The Size Before You Buy kit was extremely helpful to ensure the perfect fit, which makes a big difference in comfort and sensor accuracy. Overall, this ring combines great style with powerful health insights — worth it for anyone serious about tracking wellness without sacrificing aesthetics.

Amazing
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This is ring is the absolute best purchase I have ever made. It does so many things health wise and helps keep up with certain things for me. Recently I got sick and my ring told me something was straining my body the day before I was sick. The battery life is also amazing and that is a plus and it charges super quick. Its also very easy to set up when you first get it. This thing truly works and I would buy it again in a heartbeat.

High Quality Product
||Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.I am very pleased with this product. The technology is accurate and thorough. The ring is very comfortable to wear. At first, I was first concerned about the durability of the finish and being ceramic, but I am completely satisfied with it. I was in multiple situations where it should have gotten scratched, but it didn't! I did have a black mark on it, in which I thought was a scratch, but the cleaning pad buffed the mark right off! The ring is beautiful!
