Oura Smart Ring 4 - Stealth - Size 7 - | Non-Standard Fit – Measure with a Size Kit |Sleep, Heart Rate and Fitness Tracking Wearable | 8-Day Battery, iOS / Android Compatible

Love it. Would recommend to anyone. Particularly females. So much information, tracks multiple thing. Including workouts - slight downside is integration to Strava isn’t great but okay. Took while to get used to the feel but finding so much better than a watch.

Amazon で購入後、3ヶ月ほどでバッテリー周りの不具合に遭遇しました。症状としては充電台から離すとすぐにスマートフォンとのペアリングが解除されてしまうというものでした。 Oura Ring のヘルプセンターの右下にチャットボットがあり AI なのでありきたりな回答なのかと思えばそうではなく - 症状を入力 - 普段使用している Oura アプリのアカウントのメールアドレスを聞かれるので入力。該当メールアドレス宛に確認メールが来るので承認 - 交換対象製品を確認 & 交換品の送付先を入力 という、ほぼ 3 ステップで交換対応の申請が完了し、1時間程度で無料扱いの注文完了メールが届きました。 指輪タイプのデバイスはバッテリー周りの不具合遭遇率が高く懸念していましたが、スムーズに交換対応が行えたのでとても良かったですし、これぐらい交換対応がスムーズなのであれば月々払っている Oura の高額なサブスク代も半額分ぐらいは Apple Care みたいな保険代だと思えば割と納得感があるなと今回のトラブル発生から一連の手続きで思いました。

*It’s now been 1.5 years since I’ve had the ring. The charges are lasting about a day and a half. I charged this ring at 8 pm last night and at 4 pm today, I received a message that my ring only had 23 hours of battery left. I bought the ring because I didn’t want a health tracker that needed to be charged daily, like my Apple Watch. I’m not sure if I’ll be purchasing a new ring from Oura. I will be looking into the ringconn or ultrahuman. *I’ve had the ring for 6 months now and find myself charging it every four days. The palm side is slightly scratched. The is my third Oura ring 4. The first 2 I bought were the gold and rose gold. I returned the gold one almost immediately and ordered the rose gold. The gold looked cheap and brassy compared to my other gold jewelry. The rose gold was almost perfect. After a day of normal use, I could already see scratches. After a week of use, it was covered in scratches and had began to change color. I know the color change on the rose gold is normal, but I expected it maybe after 6 plus months of using it. I currently have the stealth. I wanted the black one, but I didn’t want to wait a few weeks for delivery. So I ordered the stealth and the color has grown on me. I’ve had it for 10 days now and I plan on keeping it. The charge is supposed to last up to 8 days, but I find that to not be true. The first charge lasted 5 days. (I still charge it less than my Apple Watch.) I’m on day 5 of the 2nd charge and I think I’ll have to charge it by tomorrow- day 6. I turned off the oxygen sensor because I heard that used up the battery and I’m only getting an extra day of charge. Also, I only let it go down to 18-20 percent. If it’s under 20 percent you won’t get accurate overnight readings. I feel like the stealth and the brushed silver are probably the best rings to purchase if you are worried about scratches and color changes. My ring currently has zero scratches after 10 days of usage. I’m leaving my rating at 4 stars because I really wanted the rose gold ring to work :/.

I ordered the Stealth color because of the reviews on scratches. I’m very active and have no marks after 2 weeks. I am having problems with it staying changed. I contacted the company and they said to allow it to fully charge. The charge does not last an entire day. It does give good information. I think I need the entire month to fully experience it. If the charging remains an issue I will return it. It’s suppose to last a week. Haven’t found that at all. It does track sleep and activity well. Everyone will need to decide what’s best for them on this one. Personal connections and information.

Oura is just what I’ve been looking for in a fitness device—and a lot more. Have been frustrated with previous fitness bands, not very accurate, tiny screens, and need to remove whenever around water. I wasn’t looking for a device that beeps, buzzes, notifies me of calls, emails, etc. Just wanted a reliable , easy to use accurate one. Oura provides tons of data, including basic vitals, steps, detailed sleep analysis , stress levels, and lots of suggestions on how to improve health. It’s waterproof, so I never have to take it off to shower or do dishes. It’s comfortable to wear, and all the data is only available to view on your cell phone, where it’s easy to read. I haven’t yet tried all the great features, including calorie counting. So much to see and learn. I have to charge it about every 4-5 days, not a week as advertised. Charging is fast and easy. Highly recommend!

I bought this ring to help me assess my health, my sleeping, my heart rate, and my o2 levels. Works just fine… Unfortunately, it thinks I am overweight. So I’ve started a diet. I mean, it didn’t tell me that… But it’s sort of confirmed it. I do think the app is cool and works well. I like the interface. Unlike a watch, you can wear this 24 seven. I only have to charge it a few hours every four or five days.
