Oura Ring 4 - Stealth - Size 12 - Smart Ring - Size First with Oura Ring 4 Sizing Kit - Sleep Tracking Wearable - Heart Rate - Fitness Tracker - Up to 8 Days of Battery Life

I've been wearing the oura ring gen 4, stealth, size 9 for exactly one month now.First off, sizing.I was between sizes 9 and 10. I opted for the smaller size using this little test: Using the plastic ring sizes, if you cannot take off the ring in the morning when your fingers are puffiest, and the only way to do so is by wetting your finger to add some slippage, then that's the right size. With the bigger size, I was able to take off the ring in the morning without using water so I felt that size was too big. One month later, I am glad I went with the smaller size. No discomfort and still using water in the morning to take off the ring before I shower.ComfortI wear it on my right index finger. I did not like in between fingers, which is the reason I wear a silicone wedding band. But overall, it's not very intrusive. It's annoying to write with a pen or pencil but that's not often.AppearanceI love the stealth color. Already got a few scratches on my palm side, which is a little annoying. But I tell myself that at least the back of my hand, the ring looks like new. I use these silicone protectors when working out with weight and it does a great job. The scratches came from handling things where I should have taken off my ring. I wish there were some way to make the scratches less visible as these scratches you see a shiny silver metal which contrasts a lot!BatteryNo issues. I charge it every few days or so while I shower. I am manually trying to keep the battery at between 25% and 75% but most often I forget that I left it charging and it goes back to 100%.Sleep TrackingI'm not a power user. I enjoy checking in the morning my sleep score and compare it to how I thought my sleep went the night prior. Pretty accurate sleep tracking in my opinion.Fitness Tracking.So we all know that the step counter is way off so I don't really care about that. However, the ring really is good at spotting fitness "events" and I love that when opening the app, there's a backlog of events that you have to confirm the type of activity. My top three are: housework, walking, and HIIT. The app gets better at recognizing the events so most times I am just confirming instead of categorizing. Overall, this level of tracking is simply encouraging me to be more active, which has lead to a good impact on my health.Overall, pretty satisfied with the ring. Glad I got it.

I’ve been supporting Oura since it was a kickstarter. I had the version 3 and decided not to upgrade but since my spouse 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.

The Oura Ring has easily become one of my top purchases—not just of this year, but honestly, of all time. It’s an incredible device that gives me real insight into how I’m feeling, what’s going on with my body, and even why certain things might be happening. Sometimes it even picks up on things before I’m consciously aware of them, which helps me get ahead of potential issues or make adjustments to my activity, sleep, or habits. It’s made a real difference in how I approach my day-to-day life and helped me make better decisions for my health and well-being.One of the standout features for me is the battery life. It lasts several days—almost a week—which is impressive for how much data it’s tracking. I also love that it’s not pushy with recommendations like some other health apps or gadgets. It’s more like having a helpful guide that you can check in with as you choose, rather than something that’s constantly nagging you to change your routine.Comfort-wise, it’s spot on. It’s the exact same size as my old ring, so it doesn’t feel any different even though they recommend wearing it on your index or middle finger. I’ve been wearing it on my ring finger without any issues—my readings are great, and it’s held up perfectly. It’s durable, waterproof, and just feels like a natural part of my routine now.I’ve already recommended it to several people because it’s been that impactful. If you’re on the fence about it, just go for it—you won’t regret it!
