    Excellent
    This review is actually for the Ceramic Oura Ring-“Tide” color-size 8-I bought the “Petal” Ceramic Ring size 7 ( last month) but could not get it to connect at all so I returned it-I tried again this month with the “Tide” Ceramic Ring-it connected easily and set up was a breeze. I have worn the ring for 6 days now after fully charging it last Wednesday when it arrived-I am impressed with battery life because after 6 days it reached 37% so I put it on the charger/it charged rather quickly -less than an hour. So far I am really pleased with this Oura Ring-I tried a couple different ring covers but just didn’t like them and so far-no scratches-I’ve done normal things-washed dishes-vacuumed-laundry etc. I mostly got it for my sleep and I must say I am amazed at the way it breaks down your sleep-quality-deep-REM-I believe it is quite accurate as I usually wake up every 2-3 hours. It also has a setting to detect sleep apnea as well as your lowest/highest resting heart rate-There are other settings for activity-calories burned-steps-workouts. Some people may have to get used to wearing it as at first it felt a little bulky but after 6 days I find it quite comfortable-the Oura Ring app is easy to navigate as well.

    Powerful and insightful ring!!
    The Oura Ring 4 is incredibly intuitive. Wonderful recommendations and insight into your health. I’m loving the Petal color and the size of the ring. The battery life is pretty good. But I really am happy that I got it!!

    The ring that smells me better than my boyfriend
    Let me tell you something: the Oura Ring 4 in Ceramic Petal is not just pretty — it is a tiny, psychic life coach that lives on my finger.This ring tells me EVERYTHING.How I slept. How I should sleep. How I thought I slept but apparently didn’t because it told me I was “restless” (rude but fair). It even knows when I’m being dramatic and calls it “elevated stress levels.”The color? Stunning. Like “soft feminine energy but also capable of running your entire wellness regimen” kind of vibe. I’ve gotten more compliments on this ring than any actual jewelry I own, and half the time people don’t even realize it’s tracking my whole life.And the accuracy? Chef’s kiss. I check it in the morning like I’m waiting for my report card. If it ever gives me an A+, I’m framing the screenshot.If you want a gorgeous ring that coaches your health, reads your mind, and gently drags you for staying up too late scrolling TikTok… this is it. Absolute perfection. 💖💍📊

    LOVE IT!!!! NO idea why people have terrible ratings. It’s AMAZING!!!!
    I LOVE MY RING!!!! I originally got the metallic ones and within a few days it seemed it’d be easy to scratch…then they came out with the ceramic and I was SO EXCITED! I got the beautiful pearly pink one and it does not scratch ever. I am a busy mom of 4 and it is beautiful, feminine and has no scratches. It’s accurate. Charges well. Connects well. It’s sooo strange that people wrote such odd negative reviews here. I’ve had ZERO problems and it’s ammmmmazing. Plus you have 30 days to return it to try so give it a try! 🙂 My hubby is going to get one too in the midnight blue from their website.

    Like a Apple Watch for your finger
    I got this from my friend for Christmas and she loves it. She likes how it tracks. Everything in the fit fits pretty good. She can use it on her ring finger or middle finger. The color is also really pretty the battery. Life is pretty good at last like a couple weeks I think the only thing is that sometimes her fingers swell up around it so she has to take it off.

    Love
    Love my new ring – so much easier than using my apple watch to track my health. The ceramic is durable and if it gets gray marks on it, they rub off with the cleaning towels provided! I forget it’s on and am able to sleep with it no problem. Battery life is insanely superior to Apple Watch as well. Love the petal color. Delivered overnight!

    Ring stopped working within 2 weeks and pretty much impossible to get customer support.
    The ring looked great, worked well for about 2 weeks but then wouldnt charge. Oura support started with ai and after that did not help, put me in a waiting line that at first said 18 minutes and kept creeping up and after 15 minutes, said it would be another 75 minutes. Disappointed, but see no option except return. Charger stopped working within 2 weeks and it is essentially impossible to get customer support.

    So much data that I didn’t know I wanted to know🤣
    Oura rings are the best! I recently gave my original gen 4 to my niece and purchased the petal in 2 sizes small as I have lost weight. The sleep tracking is on point! Same as the stress tracking! Check my sleep data and it is spot on! If you want to know just about everything you could know about your body this is a definite must have! Super comfortable and the battery life is outstanding! No vibration no screens! Just wear it and check the app when you want! I can’t imagine my day and nights without now! So far the ceramic seems far more durable than the original shiny titanium and it feels smooth and comfortable on the fingers next to the one I wear my ring on. I love that the data lives on the ring then connects to the app when you open it. Data seems super accurate to how I am feeling!

    Konnte es nicht wirklich nutzen. Das Sizing Kit fällt kleiner aus, als der echte Ring. Der wirklich sehr minimale Unterschied war leider schon zu groß. Muss mit wohl doch die kleinere Größe holen.Ansonsten sah die App ganz schön aus, blöd nur mit dem Abonnement

    Article reçu défectueux et coincé dans son socle de recharge, impossible de l’extraire. Service client oura ring compliqué et incompétentService client affreux, risque de recevoir le produit avec un souci dès le départ et coincé dans le socle (problème récurrent)compliqué faire face à ça avec l’impossibilité de contacter Amazon et la perte de temps en chat bot avec oura ring qui admet ne pas donner toutes les bonnes informations et de devoir s’améliorer , inconcevable avec ce prix de vente
