Great Product
Great Product does the job on tracking sleep, heart rate, movement etc. Very easy to set up and get going. Would recommend for those that do not want to wear a smart watch.

Great item, very efficient at tracking
I love this ring, it does everything and more that you could ever want from a fitness tracker. It also works really well alongside your Apple Watch. I would highly recommend and it was sent to me within 24 hours.

Expensive but good value!
Really impressed, it's been tracking my sleep and helping manage my diet and exercise. It's comfortable and pretty stylish. The app is easy to use and doesn't bother me all the time with ads or useless notifications. It's very expensive and having to pay a subscription isn't the best but I think it's pretty good value for the technology in it. It was really easy to set up and hasn't had any connection drop outs or other issues. I'm a little concerned that the next ring will not be compatible with my current charger or case if I decide to get one. I hope it will be but the 3rd gen isn't compatible with 4th so that's something to know if you're buying in a few years and the 5th gen is due out. Hopefully I'm wrong and backwards and forwards compatibility won't be a problem. I like the idea of being able to give friends a discount link right from the app but it would be better if I got a month of my subscription free if they buy. I much prefer this form factor to a watch but you do give up easy heart rate monitoring so maybe a widget that can be pinned to a phone screen or even a small screen on the ring would be something cool to add in the future. Blood pressure monitoring would also really be a cool thing to add but that might not be possible. One other thing to keep in mind if you are buying is it really needs a lot of data to get the most out of it so for the first couple of weeks to a month it won't give you all the readings. In conclusion, I love it, I'm really pleased with the fit and the colour I chose. The app is great and I wish I'd had one years ago. Very happy customer.

Good product if its in the box when delivered.
My wife and I bought two rings. Mine arrived complete, but my wife's was missing the ring. So I ordered another one, thinking it was just a mistake. Her second package arrived the next day with no ring in it AGAIN.

Tracker
This is great at tracking sleep and stress. I personally believe the steps/ calories burnt are wrong but nothing is 100% accurate that way. I have had this ring since December, I do use ring covers to protect from scratches. The charge did last over a week each time but now it needs charging every 4 days. The oura app is about 5pound per month and the natural cycles is about 12pounds per month but this has helped me a lot, I'm very happy with this

Nice ring
Works, decent battery life, comfortable and the app gives me useful stats and hints. I wish the stats did not need a subscription otherwise 5 stars

So So Happy!
I hesitated for a while before investing in this gadget. And I love my Gadgets! but after doing some homework on the competition, I decided to jump for it. First, the fit and metal colour are great, I couldn't be happier, the quality and durability is insane, i do everything with it, I rarely take it off. The connectivity to my Samsung Z Fold6 was flawless, no hiccups, plus, everything you open the app, it updates in no time. so great compatibility. Now, you need to give it time to gather data about you, of course... it will not happen overnight which is quite right, but the intel you get afterwards is great. Your body age, sleep quality, energy available, your stress, it is such a great little ring. it is a lot of money for such a small device but the value for money is worth it. I highly recommend it if you are curious and want to be nudge in the right direction for better health.

Looks Great, Rugged & Works Well. 6-7 Day battery life.
This is the second Oura Ring I have owned, this one had a great discount in the Amazon sale so it was worth upgrading from the 3 to the 4. It looks great in Black Stealth and can handle knocks and abuse of a manual labour job. I’ve had it 6 weeks now and worn it every day to work and I still don’t see any scratches dents or marks on it. Battery life is also exceptional at 6 days, maybe 7 at a push. But it doesn’t take long to recharge either. The App that comes with it is very good as well and covers the same matrix that an iOS or Android watch does including sleep, heart rate, oxygen saturation, steps, Activity and even stress. It gives a detailed breakdown of each and depending on how interested you are you can breakdown by day, week, month or year. It can also provide weekly, monthly and yearly reports on All matrix monitored. So if you’re way over your step goal for example the app will suggest setting a higher one. It does the same with sleep etc. There is also a Rest mode if you pick up an injury or illness. I was very surprised when I had the flu and the App notified me that something was going on with my body and suggested rest mode. So if you’re a Sporty individual or just someone like me who likes to keep tabs on my health I would highly recommend this ring.

I didn't find this more accurate than my Samsung Galaxy smart watch. I had higher hopes. It looked nice. Pretty expensive for the same features as the watch.

Ich suchte eine Alternative zur Sportuhr / Smartwatch und wurde fündig. Der Ring macht nicht nur optisch etwas her, sondern liefert einem auch Daten über die eigene Gesundheit. Er ist ein guter Allrounder und macht einiges sichtbar, was man im Alltag doch gerne übergeht. Mit Hilfe des Ringes achte ich nun mehr auf Bewegung und Ruhezeiten. Die Auswertungen sind zudem hochinteressant. Ich kann den Ring jedem empfehlen der auf der Suche nach einem Gerät ist, welches den Fokus auf die Beobachtung der Gesundheit legt. Sollte der Schwerpunkt eher auf dem Sport liegen, würde ich zu einer Smartwatch tendieren.

睡眠の質と日々の健康状態を把握したくて購入。 現在使い始めて5ヶ月目。 普段はPixel Watch 4をつけているけど、両方使っても全く邪魔にならない。 つけている感覚があまりないから、寝る時も気にならないのがいいところ。 事前にサイジングキットで指の太さを測ってから買ったので、フィット感はばっちり。 キットの購入代金分がしっかり割引になったのも助かった。 最初のうちはただの記録だけど、30日くらい使い続けると自分のサイクルが見えてくる。 データが蓄積されて、日々の体感とストレス測定のグラフがぴったり合うようになる。 5ヶ月間使ってみて、とくによかったのはこんなところ。 ・時計と併用しても指や手首が快適 ・30日目あたりから自分の疲れのピークがわかる ・ストレス状態の測定精度がかなり高い ・体調不良の兆候を事前に教えてくれる 一番驚いたのは体調不良の予測。 実際に体調を崩し始めたタイミングで、アプリがしっかり不調を検知していた。 ついつい無理をして、自分から休みをとれない性格の人におすすめ。 客観的なデータで「そろそろ休んだほうがいい」とストップをかけてもらえる。 今ではすっかり手放せない、健康管理のお守りになっている。
