I love my Rose Gold Oura!
I know the Oura Ring comes at a steep price but I truly think it is worth it. I have had it since February and I only ever take it off to charge it. The biggest con is that the rose gold coating has a few chips on the outer edges and I have scratched it up pretty good. I have put this ring through a lot though so I’m not that surprised. You can buy clear silicone “cases” for it but it dulled out the brightness of the color itself. I still get compliments on how pretty it is even though I have been rough with it. The first week wearing it was an adjustment. At first it felt heavy and bulky but after the second week I stopped noticing it. I got a size 8 and it’s the perfect fit and feels comfortable. It doesn’t ever slip off but it’s easy to remove. My main reason for getting the Oura Ring was to help me keep track of my cycles and ovulation. I love the app and everything it has to offer. Overall the quality is great and I recommend this ring to all of my family and friends.

Phenomenal Sleep Tracking Tool
I got this Oura ring for my wife for Christmas this past year and she loves it as well as the rose gold color. It's a very good way to take control of your sleep and improve sleep quality. The ring tracks your sleep down to the minute, is crazy accurate, and works with an app that, once installed, works offline and connects to the ring through Bluetooth. Every morning you can get a full breakdown on the app of your sleep pattern for the night including sleep stages (light, REM, deep), heart rate, heart rate variability, body temperature, respiratory rate, total sleep vs time in bed, your sleep efficiency, your "body clock" and even "sleep debt" (which tracks how much sleep you're getting vs how much you need for your body type). It also tracks the menstrual cycle for women, which my wife uses and likes a lot. She's been able to figure out a pattern based on her heart rate that happens the day before her period actually starts, which works every time - super cool! Of course it does other things like tracks your steps, exercise, you can log your meals etc. Too many things for me to include in this review. The ring fits my wife's finger perfectly. Before you buy you have to purchase the ring sizing kit, which is cheap, and you can use it for friends if you refer people (which you can get awarded for monetarily). The sizing is pretty easy, wear one of the sizers for a day and make sure it's comfortable and then order your ring. I've also seen the ring sizing kits on display in places like Costco or Best Buy, so that's another option without having to buy the kit. The battery lasts about a week, which is pretty good. And it charges in less than an hour, sometimes half an hour if she's charging it more regularly than a week (which your supposed to do). My own Oura Ring 4 is over a year old and I have to charge it every 2-3 days. I admit, I did not follow their recommendations for maintaining the best battery life, so can't complain there. Overall, Oura Ring is fantastic and I'd highly recommend it to anyone. My wife and I have both been able to improve our overall sleep quality since using them. They are a very good tool for that if you want to prioritize sleep in relation to health (which anyone should).

Gimmick thus far
Not seeing the value in this product. I’m 100% a half size which they don’t offer so I’m not sure if it’s just because it’s either too small or too large. It detects I’m napping when I’m not, I sleep terribly but because I sleep terribly every night it gives ‘GREAT! You’re right within your typical sleep score!’ feedback as if it’s a good thing. It doesn’t detect activity. I regularly go on a 5K run or a 30+ minute peloton ride and it never detects activity. I’ll exchange it to see if perhaps I just got a defective ring but I’m not entirely optimistic about it. Also, the app is kinda useless and non intuitive. For each metric, when I tap on it, I’m taken to a definition of the metric but there is no actual measurement of my body function for whatever the metric is supposed to measure. Who cares how wonderful it is to know what body temperature is if it doesn’t measure mine? Also, unless you need help with knowing what your period is, the women’s health feature is useless. No menopausal support whatsoever. Finally, it scratches SUPER easily! The rose gold was beautiful for a few hours but after the first day of wearing it, it looks like a cheap piece of costume jewelry obtained from the doll@r store. And finally, you can’t upload health metrics from your own medical provider! In order to enter your health information, such as triglycerides, etc., they force you to go through OURA to Question Diagnostics and pay them to run bloodwork! I already have all my information via my doctor and pay $3000+ per month for health insurance! NO WAY am I going to go pay extra for that! What a RIP OFF!

Great health tracking!
Love the Oura ring is not true to normal ring sizes so definitely use a sizing kit! Becomes comfortable as you wear it an get used to it. I feel like it tracks the heart rate and sleep well but maybe a little less accurate on the activity. Super easy to set up and use the app but does come with a subscription charge. Waterproof I do dishes and shower and everything with it on! But does scratch very easy.

Limited Warranty - buy the optional insurance
I'm VERY disappointed that my ring lasted less than 10 months. I purchased it on 10/28/204 and contacted Oura Customer Service (CS) on 8/19/2025. They sent me a replacement ring with 2-day delivery. However, CS indicated the replacement will only have a warranty covering the remainder of the first ring's warranty or 90 days from delivery, whichever is longer. That means the new product will have less than a 1-year warranty even though I'll only have the new product a few months. Seriously? I hope I have better luck with the replacement. In hindsight, I should have purchased the optional Protection Plan. Lesson learned.

Love The Tracking
I have been using this ring now for almost 3 months and I love its performance. It truly does help me move more with its tracking and I feel it is pretty accurate. Battery life is good and usually last 5-6 days on one charge, and charges quick. I will say the ring does scratch easily which sucks since you have to wear it to get results. Ring seems waterproof, I wear it in the shower and have had no issues with it

Dependable and sturdy!
I chose this ring over cheaper options because of the reviews. I am NOT disappointed. I’ve had it a couple of months now, and it’s crazy how detailed the readings are. It’s light weight, durable, and has amazing features. Also- MAKE SURE YOU BUY THE SIZING KIT! These are not “typical” ring sizes. If you get the sizing kit and follow instructions, it will fit perfect and you’ll be fine.

Amazing results over time of so many markers called “Biometrics”
I have had my Oura ring for two months now. I like it even more than I ever imagnined. I ordered the Rose Gold, because the regular "gold" looks more like an orangey green yuck color. I use a clear silicone ring cover ordered here on Amazon to protect my Rose Gold Oura Ring from scratches. I am so impressed with the app results and love looking at them each morning. I take pics of my food, log activity and am most amazed at the sleep data, oxygen sensing, the levels of sleep (Deep, Light, REM etc) and the body temperature results are fascinating. The app sensed that I had an elevation in my body temperature and higher heart rate while sleeping- the day before I realized that I was sick. I would HIGHLY recommend getting the plastic ring sizers for ten dollars (they apply that towards purchase of your ring) for sleeping in and wear for a few days. Our fingers swell and it is great to try the sizers on to decide which finger to wear it on. They recommend the index finger is the best for the biometrics. (Think of when you are at the Dr or ER and how they put a pulse oximeter on your index finger.) It is more reliable place than a smart watch on your wrist according to data I’ve studied. Update: over five months later and I am still really enjoying the OURA ring and highly recommend it. I have learned several things about the quality of my sleep. My sleep is affected by how early or late I eat dinner. The app showed me that the supplement valerian affects my heart rate during sleep. I also am very encouraged by a sleep score from the night before that shows I had benefit even from light sleep. I will think that I got a terrible night sleep and then I look at the data that it really wasn’t that bad. It really helps give me a better perspective and outlook.
