    • Stylish, Insightful, and Surprisingly Comfortable — Love Everything About It
Color: Rose Gold Size: 11
I’ve been wearing the Oura Ring Gen 4 in rose gold for several weeks now, and I genuinely love everything about it. It’s rare to find a health and wellness device that looks good — but this ring really nails it. The design is sleek and minimal, and the rose gold finish adds just the right amount of style without being flashy. It is thicker than your average accessory ring - but, it goes with everything, and I love that I can wear it 24/7 without it looking like a fitness tracker. I don't like the bulkiness of other devices so this is perfect. Comfort-wise, I barely notice it’s on — even while sleeping, which is impressive. The data it provides is clear, comprehensive, and genuinely helpful. I’ve learned so much about my sleep patterns, stress, recovery, and overall activity. The Oura app does a great job of translating data into simple, actionable insights without overwhelming you. Battery life is solid (I charge it every few days), and the charging process is quick and easy. I also appreciate the emphasis on recovery and readiness — it’s a more balanced and holistic approach than many fitness trackers I’ve used in the past. If you want a stylish, low-profile device that delivers high-quality health and wellness tracking, the Oura Ring Gen 4 is absolutely worth it. ... show more

    • Oura is terrific!
Color: Stealth Size: 7
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! ... show more

    • 100% better sleep
Color: Black Size: 7
I’ve been supporting Oura since it was a kickstarter. I had the version 3 and decided not to upgrade but since my SO lost her ver 3 I gave her mine and ordered this. If you’ve never had an Oura ring: this product is amazing. So comfortable, more so than a watch. The app is great, I’ve learned so much about sleep habits, what to do and not to do for sleep. Lovers of science will like this, you can literally experiment and see the exact results for yourself. Accuracy: I would say this is 95% accurate. Again, I’ve been using this for about 5 years. So I’ve seen the accuracy improve IMMENSELY over the years. Version 4 is the best yet. Better than any other sleep tracker I’ve tried and I’ve tried a lot. The biggest inaccuracy is every now and then I’ll get up to pee in the middle of the night and it will think I woke up for the day. Sometimes it knows I just went to pee sometimes not. Since I noticed it, I take my ring off if I get up to go to the toilet and it fixes the issue—just don’t forget to put it back on! Key info for consumers: the fit is slightly larger than the version 3. To be exact I would say the version 4 is about half a size larger. So the new size 7 for example, would be a size 7.5 on the old version 3 and older models. The new size is great for me. My old ring was snug on my ring finger. So now I can wear the new one on my pointer finger and even middle finger depending on how hot it is. It all depends on the temperature outside due to our hands expanding/shrinking in heat/cold. Hot days I’ll wear on my ring finger, cold days I can wear on my index or middle finger. Conclusion: I love the Oura ring. It’s more comfortable than an Apple Watch or a woop in my experience. Way, WAY more comfortable. It’s also very accurate and the info is extremely useful. It’s increased my understanding of sleep, the importance of exercise for sleep, and dare I say, made me a better person. Getting better sleep takes effort, and this is merely a tool to help you do that. Getting better sleep can 100% make you a better person and I speak from my own experience. ... show more
