OURARing 4 - Stealth - Size 10 - Smart Ring - Unique Sizing, Not Standard US Ring Sizes - Size First - Sleep Tracking Wearable - Heart Rate - Fitness Tracker - Up to 8 Days of Battery Life

I’ve been using my Oura Ring for a month now, and I’m genuinely impressed. It’s sleek, lightweight, and easy to forget you’re even wearing it which is exactly what I wanted in a wellness tracker.The sleep tracking is incredibly detailed and has helped me better understand my sleep patterns. I’ve started making small changes to my routine based on my readiness scores and have noticed a real difference in my energy levels.I also appreciate the insights on recovery, heart rate, and activity without the bulk of a smartwatch. The app is user-friendly and the daily reports feel like a personal check-in.The only thing to note is that sizing can be a bit tricky – I used the sizing kit before ordering and I’m glad I did. Battery life has also been solid; I only charge it every 3-4 days.Overall, this has been a great investment in my health and well-being. If you’re looking for something subtle, smart, and science-backed, I highly recommend it.

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!

The ring fits on my right pointer finger just fine. That finger, for whatever reason, is wider than my left finger but it still fits well. After sleeping through the night, it’s a bit more snug. The information the Öura Ring provides through the app is helpful as I’m an extremely light sleeper. It has helped me understand my sleeping patterns and has predicted my cycle perfectly twice now. It records exercise/activity better than my Gen 8 Apple Watch but I’m not really comparing the two too much. It does have some light scratches but that’s to be expected when wearing it all day. The battery is at 88% after a full days use and I typically charge it in the shower. I would recommend this to someone who is looking for health and wellness details for themselves as the Ring really does provide great detail.

Amazon, despite complaints, views the Ōura Ring Sizing Kit as the same or a similar item as the Ōura Ring 4, itself... thus, two DIFFERENT reviews AND ratings for two COMPLETELY DIFFERENT products.--------------1) THE ŌURA RING SIZING KIT / 5-StarsŌura states that the Ring 4 sizes are NOT the same as traditional ring sizes.I did NOT break out my Ring Sizing Loops to determine the veracity of that statement because the cost, of the Ring 4 Sizer, on Amazon is applied as a credit towards the cost of an Ōura Ring 4 WHEN purchased via Amazon.I will say that there is perhaps a little difference, compared to traditional ring sizes, but I'm not sure that it's much because I ended up with the ring size that I thought would work.Interestingly enough, size 10 that I expected for the middle finger was a perfect fit for the Index finger, which is normally a traditional 9... so there is some difference in the sizing and I wholeheartedly recommend procuring the Ōura Ring 4 Sizer BEFORE purchasing the Ōura Ring 4.NOTE that the Ōura Ring 4 Sizer does not work for all Ōura Ring models, so anyone deciding to purchase a previous iteration of the Ōura Ring, due to cost decrease and/or a Sale, will need to utilize the correct Ōura Ring Sizer for the model ring chosen.If there is a question of Sale or Discount Pricing, due to the delay from checking ring sizes, then I suggest an online Chat with Amazon Customer Service representative to make sure that you can lock in any discounts to use after verifying the correct Ring size.FYI - Ōura recommends wearing the sizing ring on the finger that will bear the ring, in order to become accustomed to the ring size/feel and to see how well it fits throughout a normal day.I followed that advice and I believe that everyone should do the same.----------------2) Ōura Ring 4 / 1-StarFirst, even with the ring sizing kit and wearing the sizer non-stop until the Ring 4 arrived, the size of the Ring 4 in only whole sizes proved inadequate. My hands clearly fluctuate enough in size to be an issue, regardless of the finger or hand that is used.Next, the heart rate (HR) was always available and showing in the app, signifying that the Ring 4 was measuring the HR, HOWEVER, the app called to show the graph of the HR for over two (2) weeks, meaning there was no history nor any assessment available.Next, the Sleep function, even with learning curve, seemed to function out of the box, HOWEVER, after the first recharge of the Ring 4, there was an issue with accurately recording start and stop points of Sleep AND eventually the app would show No Sleep Data AFTER uploading/updating UNTIL THE NEXT day. There was no event showing for sleep ALTHOUGH the Ring 4 clearly annotated the Start of the Sleep period the previous night.Next, even after more than three (3) weeks of use, the app has failed to graph the Blood Oxygen Saturation, in spite of showing the data observed and available to see at any given moment. Again, I find this to be very odd and indisputably useless to the user.Next, the App is full of "flash" or substance but in terms of a quick overall view of all the numbers, like most Apps, no such uncluttered view can be found. While the plethora of information and links is appreciated, the search to locate immediate data numbers across all items is tedious, frustrating and unappreciated.To provide an analogy, it's like having to read an entire book to search for and locate the Synopsis of the book. For those who aren't into books, then it's like watching a TV and THEN SEEING the Preview for the show that you just watched.I and most users seem to prefer a Table of Contents approach where the Raw Data is shown and then you can click to go to the Analysis, Assessment and Suggestions for that particular Biometric.In short, the App's interface is beautifully flashy and showy but about as useful up front as a Show Pony on a crop farm.That makes it overwhelming, even to those who are focused readers and moreso to the vast majority who are not.Finally, many details and assessments are NOT available for anywhere from four (4) weeks to three (3) or more months.While understandable, it makes it impossible to fully assess the personal value and utility of the Ring 4 in the 30-day period for returns.That means that the $400+ ring and the annual subscription fee is only acceptable for those with money to burn, so to speak, because all of the shortcomings or issues, even if expandable and temporary, outweigh the cost of what is actually a pretty doggone accurate piece of tech wear, resulting in the clear choice to return the ring.AND... there is one other issue to consider which is that if your hands swell, perhaps from work, or shrink, perhaps from weight loss, then your $400+ ring AND subscription become useless... until you purchase another Ōura Ring that does fit.Based on my research and experience, there are equally accurate smart fitness watches with solid Apps and reasonable insights and suggestions based on the assessment of the biometrics.Also, there is another smart ring on the market that appears to rival the Ōura Ring in accuracy, provides an seemingly identical App for all appearances seen, comes as an adjustable ring using the same high-end materials and sensor setup AND which additionally boasts being approved and classified as a Medical Grade Device, instead of a Consumer Grade Device.All of that at a far, far lower cost AND the same updates, assessments, insights and suggestions BUT with NO subscription fee.That being said, I am a Go/No-Go tester of products meaning things are either 5-star or 1-star with enough details for people to decide that my 1-star item might be good enough to be their 3- or 4-star item.The Ring 4 failed to make the grade for my needs nor was it able to justify keeping the ring to see if things improved or the money was worth the extended wait for certain observations, but it was remarkably accurate when comparing data to manual results, such as HR, SpO2, etc.There is no blood pressure data, for those in search of BP function. I am not sure that BP could be accurately obtained below the wrist at this point in technology, but maybe in the future.REMEMBER that when returning an Ōura Ring, you MUST also CANCEL the Ōura App Subscription as it is a separate financial issue from the purchase.The subscription is free for the first 30-days and a part of setting up your account before you are able to use the App, so it's an easy thing to forget.3) Addendum -- there is a charging cable organizer with a carabineer that works GREAT for the Ōura Ring 4 charging station and cable that is available on Amazon AND IS HIGHLY RECOMMENDED.That is my next review and it will be 5-Stars.It was kind of a why-the-heck-not afterthought purchase that became an INSTANT 5-Star Should Have item as soon as I unpackaged it!!!!

I've had this for a few months now and it is definitely a high quality personal item! Lately it does update alot, but I see it as being a highly effective device reporting what represents what it is that I'm doing. It is totally worth all the feedback and analytics to buy a full years subscription and have it automatically setup to do that. I appreciate that their is alot to track on yourself and learning how to improve one's lifestyles and more! It does take some time to learn how the pages are setup in a layman terms, imho. I really like the bright gold color as it matches my watch and it's light, comfortable and stays fitted on my finger. I can easily find it when it's on it's' charger in the dark too.Like any ring, you have to remove it from your finger for cleaning and occasionally check the positioning throughout your day.
