Looks great.
Love this ring. Have turned a couple of my friends to it. Subscription sucks… but meh.

Premium Price, Disposable Product
Complete failure after one year. Pathetic support. After roughly one year of use, my Oura Ring simply stopped working. It stopped connecting to my phone, stopped syncing, and effectively became an expensive piece of dead metal. The most frustrating part is not even the hardware failure. It is the after-sales experience, which is frankly unacceptable for a $400 product. The only way to contact Oura is through a poorly designed AI chatbot that goes in circles and solves absolutely nothing. No real support, no accountability, no effective resolution. If you are comfortable throwing away $400 after a year with zero meaningful customer service, this is the product for you. If not, I strongly recommend looking elsewhere. There are better alternatives with real support and companies that actually stand behind what they sell. This is not a premium product. And it is certainly not a premium company.

Make sure you read that it’s a size 12
Size before you buy is misleading. It came as a size 12.

Amazing
Having used the Apple Watch Ultra and being a long-time Fitbit fan, I can confidently say that this ring is the best health tracker I've ever tried. It is very accurate and it's easy to forget that you're wearing it, unlike the Apple Watch Ultra. I highly recommend this ring to anyone looking to lead a healthier lifestyle.

Battery life is very poor 3 days
Nice features, bummer you have to pay for using the app. Battery life is the bigger reason I will end up change to another brand.

Fits perfectly
Size was the same that my previous one.

I enjoy the insights it provides. It is bulkier but got used to it fairly quickly. I am happy I got the brushed one as it does get scratches and milage, especially due to its size. Nothing major though. Charing every 4 days or so i also nice. Works nicely alongside my Withings watch.

Quite an eye opener. Love gadgets, this one rates very much near the top. Do your research before buying. For lots of sporting activities apparently a wrist band is more accurate but for daily living the Oura ring is just great. Full heartedly recommend.

not really worth it. i chosed the matt(brushed) version so the scratches are not that noticeble. But you still see them same as a regular on. Do not chose this over the other if you only think about this fact. and also being useless without the subscription is not that great! don't get me wrong, is a good device, but not great!

Ring sehr schön verarbeitet. Akku hält 8 Tage. Messungen aus meiner Sicht sehr genau. Hatte Apple Watch und Ring 3 Tage parallel getragen, extrem ähnliche Ergebnisse. Komfort am Mittelfinger ist ok. Würde ihn wieder kaufen. Einziger Nachteil ist die kostenpflichtige App um die Daten voll zu nutzen. Diese dürfte gerne etwas günstiger sein.
