Best bit of health kit I’ve bought!
Completely addictive, so interesting in terms of the info - I’m debating moving away from my Apple Watch as the battery on this is so much better - I always charge my watch overnight but the sleep info on the Oura is great, amazing accuracy on the patterns! The battery life i would say isn’t quite as long as described but still a few days so good enough! Super easy to set up and use, debating the travel charge case but at the moment not sure it’s needed as the charger is just USB C. Definitely worth ordering the fitting measure, I wouldn’t have had a clue but annoying when you decide you want to go for it as adds a few days before you can purchase. Once bought though a perfect fit. I bought the brushed silver and have had quite a few compliments, it’s a really nice, non flashy piece that blends well with other items of jewellery. Expensive but so far I would say worth it :)

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.

Love my Oura
Love my Oura! Wear it as a wedding band and never take it off 😀 Battery life is over 5 days and is robust and well built. Mine is a size 10 and I never notice I’m wearing it. The app is great and auto activity tracking is spot on.

Please don’t waste your money!
Don’t waste your money!! I have had mine 4 months and the battery is draining fast!! A very expensive piece of crap in my opinion. You also have to pay a subscription which is ridiculous!! If you want to track your health get a watch. I got conned into getting this to take my temperature, the way it is going it won’t even work in a months time and I’ll have to fork out more money! You also have to buy ring covers every month because it gets scratched very easily and it just looks like an eyesore the covers don’t last very long either!

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.

REVIEW OF OURAL RING 4
IT IS GOOD, BUT NOT AS THIN AND CONFORTABLE AS OURA RING 5. THE SUBSCRIPTION IS RATHER ANNOYING, PARTICULARLY IF YOU CONSIDER HOW MUCH YOU PAYED FOR THE RING. AT LEAST THE CHRGER IS INCLUDED IN THE PACKAGE, IN CONTRAST WITH THE OURA RING 5. IT IS THE BEST RING TO TRACK YOUR SLEEP, BUT NOT ACCURATE FOR WORKSHOPS AND IT IS DIFFICULT TO USE IT WHEN YOU LIFT WEIGHTS...SO IT IS COMFORT WHEN YOU SLEEP. BATTERY LIFE IS GOOD. BEST OF ALL IS THE APP....ALTHOUGH I AM EXPECTING TO BECOME BETTER SINCE YOU PAY FOR IT AND THE APP OF ALL THE OTHER RINGS IS FREE...

Don’t know where I’d be without my Oura
Don’t know where I would be without my oura ring! It’s so interesting to know all the data about sleep, heart health etc. If you’re thinking about getting one, let this be the review that gets you one! Very, very convenient. I don’t wear my Apple Watch anymore as I’m a nurse and can’t wear watches. Would say that this is more accurate and better. Its tracks fitness, steps, sleep, women’s health etc. It also helped me conceive which I’m very grateful for. It is ‘bulky’ but you do get used to it! I often speak very highly of this product and got atleast 5 people to get one. I don't know where I’d be without my Oura ring

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.

休むのが苦手な人に。体調の変化を事前に教えてくれる魔法の指輪
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。
