    • Wish I bought this sooner
Color: Stealth Size: 10
I’ve had my Oura ring for about 2 weeks now, and so far I love it. I bought a “random” cheaper ring first, because the price tag and subscription for Oura turned me off, but the other one didn’t work. I returned it and figured I’d try this. First off, get the sizing kit. If you try to guess based off of other rings, you’ll probably be disappointed. I sized it off of my pointer finger, with the intent to move it to smaller fingers as I start losing weight. (I have no interest in having to buy multiple rings if I can avoid it.) It can be worn on either hand, so I have lots of options to swap too as I hit my goals. The ring isn’t tiny, but it’s not obstructive. I’ve gotten used to it and it doesn’t bother me at all. I can shower with it on, wash my hands, go swimming…all the things. As for the tech and the app, super user friendly and easy to use. Everything is pretty intuitive and the data that doesn’t automatically make sense comes with explanations. You can see how everything ties together. Its predictive nature is also 2-for-2 for me. It’s reads your data in its entirety and tells you when things are a little off. I got a warning one morning when I woke up, and spiked a fever that evening. It’s also accurately predicted the timing of other things that women may find useful. One of the main reasons for me getting the Oura was to track sleep. In my opinion, it’s been pretty spot on. If I feel like I’ve laid in bed all night staring at the ceiling, my data matches that. If I feel like I passed out as soon as my head hit the pillow, the data matches it. When I wake up feeling super refreshed, and check the app, it says I slept well. When I wake up feeling like crap, surprise! The app says I slept horribly. From there, it sets your activity target for the day - based on how rested your body is. All in all, I am very happy with my purchase. Only regret is that I spent so long deciding if I really wanted it or not. But, I guess the good thing is that it seems like this model (Oura 4) has fixed a lot of problems some of the older models had. Definitely recommend! ... show more

    • I love it!!!
Color: Black Size: 11
I have a samsung watch but decided to try the Oura ring. I love it. The app seems to provide much more information, especially after you have worn in a few months because it detects trends and tells you about them. The worst thing about it is if you buy it because you want to lose weight, you can quickly start dropping ring sizes if you are starting out with a LOT of weight to lose. Definitely start with the sizing kit and keep an eye on your return window. If you drop a ring size, return it and buy the next lower size. Once you pass that window, you will have the option to move to the next biggest finger. I dropped two ring sizes in 60 days. I might have one more decrease left in my then I will move to index or middle finger most likely. The charge on size 11 will last five, maybe six days ith O2 sensor activated. I think it does better at recording accurate sleep than my watch does but i still wear them both and compare. It is supper easy to use and the quality and design of the ring are excellent. It has received some pretty big blows and it still looks brand new. I only wish they had a program to exchange it for weight loss. The ring doesn't get much of the credit for losing weight but i think it definitely helps. I"m also not a fan of paying for the app but i do think it is much better than samsung app. I did see Target lets you return them for 60 days if you purchased with Target Credit Card.

    • 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

    • Difficult fit for accuracy, relatively pricey monthly subscription
Color: Black Size: 7
I invested in this ring mainly for sleep tracking and it’s awesome! It does everything it should and more. Things I don’t understand it explains well and I like “Advisor” for questions and suggestions. My main issue is size, I’m definitely frustrated. Got the size 7 which was supposed to fit well, but my fingers get cold and the ring is too loose. I live in NH so it’s chilly then it’s hot and humid during our Summer months and my finger swells. So, after 2 months of wearing it it’s definitely too big, the return window has closed so I had to eat the money for a size 6, it just doesn’t fit any finger well. Ideally I am a size 6 1/2 but this does not come in half sizes. Fingers crossed the 6 works. Also, I got it in black and it does have a scratch already after 2 months which is super odd as I’m a Nanny, I do no crazy stuff that involves being hard on my ring, not sure how the scratch happened. I also feel the monthly subscription is a bit pricey for an already very expensive ring. The data is valuable but I wish the subscription was cheaper, so be prepared to pay that on top of the cost of the ring. ... show more
